Prize Draw Research Incentives: Free Entry Routes, Registration Rules, and the Sample You Actually Buy

Answer first: A prize draw incentive is a lawful promotion only when one of three elements is missing: a prize, an element of chance, or a requirement to pay in order to enter. Research teams almost never remove the prize and almost never remove the chance, so the entire compliance burden falls on the third element. In the UK that means satisfying the four cumulative conditions of the free entry route in Schedule 2 of the Gambling Act 2005. In the US there is no single federal statute at all; you inherit a state-by-state patchwork in which Florida alone requires you to file your rules seven days before launch and bond the full prize value once announced prizes exceed $5,000. And before you take any of that on, check the arithmetic: a draw does not buy you a cheaper sample, it buys you a different one.

This guide is written for research and insights teams, not for lawyers, and it is not legal advice. It is a map of where the tripwires are so you know when to get advice and what to ask for.

Why research teams reach for prize draws

The appeal is entirely budgetary and it is easy to see. Two hundred completed interviews at a $25 guaranteed incentive costs $5,000 in incentive spend alone. One $500 prize draw across the same two hundred people costs $500. On a spreadsheet that is a ninety percent saving, and it arrives at exactly the moment a research plan is being cut for budget.

The second attraction is operational. Guaranteed incentives mean two hundred payout events: two hundred email addresses, two hundred gift card redemptions, two hundred reconciliation lines, and in the US a tax reporting question once anyone crosses the annual threshold. A single draw is one payout. Teams without dedicated research operations support reach for the draw because it is the version they can actually administer.

Both of those advantages are real. What follows is what they cost.

The three elements: prize, chance, payment

Almost every jurisdiction that regulates promotional draws works from the same three-part structure. A scheme is a lottery, and therefore heavily restricted or unlawful for a commercial operator, when all three of the following are present at once:

Every compliant promotional draw in the world is built on removing the third element. That is what the phrase no purchase necessary is doing on the back of a cereal packet, and it is what a free entry route is for. Once you understand that the whole architecture exists to break the payment link, the specific rules stop looking arbitrary.

The UK position: Gambling Act 2005

The UK gives you unusually precise statutory text to work from, which makes it a good place to learn the shape of the problem even if you never field a study in Britain.

Section 14 of the Gambling Act 2005 defines a simple lottery as an arrangement where persons are required to pay in order to participate, one or more prizes are allocated to members of a class, and the prizes are allocated by a process which relies wholly on chance. A complex lottery is the same thing where prizes are allocated by a series of processes and the first of those relies wholly on chance. Section 14(4) makes clear that prize includes any money, articles or services whether or not described as a prize.

The definition of paying is where research teams get caught, and it is deliberately wide. Schedule 2 paragraph 2 says a reference to paying includes paying money, transferring money's worth, and paying for goods or services at a price or rate which reflects the opportunity to participate in an arrangement. That last limb is the one that catches a draw restricted to paying customers or bundled into a subscription.

Three further paragraphs remove the obvious workarounds. Paragraph 3 says it is immaterial to whom a payment is made and who receives benefit from it, so routing entries through an agency does not help. Paragraph 4 says it is immaterial whether a person knows when he makes a payment that he thereby participates in an arrangement, which means an unadvertised draw attached to a purchase is still a draw. Paragraph 6 treats a requirement to pay in order to discover whether a prize has been won as a requirement to pay to participate, and paragraph 7 does the same for a requirement to pay in order to take possession of a prize. You cannot make entry free and then charge for the envelope.

Paragraph 5 carves out the ordinary cost of communicating: sending a letter by ordinary post, making a telephone call, or using any other method of communication, provided the rate is a normal rate, defined as a rate which does not reflect the opportunity to enter a lottery. A premium rate line is payment. A standard email is not.

The free entry route. Schedule 2 paragraph 8 is the provision that makes research prize draws workable, and it imposes four conditions that must all hold together. Each individual who is eligible to participate must have a choice whether to participate by paying or by sending a communication. That communication must be either a letter by ordinary post or another method which is neither more expensive nor less convenient than entering by paying. The choice must be publicised in such a way as to be likely to come to the attention of each individual who proposes to participate. And the system for allocating prizes must not differentiate between those who participate by paying and those who participate by sending a communication.

The third and fourth conditions are the ones that fail in practice. Burying the free entry route in clause 14 of a terms page is not publicising it in a way likely to reach everyone who proposes to participate. And giving paid entrants one ticket and free entrants one ticket only if they also complete a form does differentiate.

The skill escape rarely works. Section 14(5) says a process requiring persons to exercise skill or judgment or to display knowledge is still treated as relying wholly on chance if the requirement cannot reasonably be expected to prevent a significant proportion of participants from receiving a prize, and cannot reasonably be expected to prevent a significant proportion of those who wish to participate from doing so. Both limbs have to be satisfied. A tiebreaker question that ninety-five percent of people answer correctly fails the first limb, and a question hard enough to pass it will usually fail the second by deterring entrants. Do not build your compliance position on a tiebreaker.

The US position: no federal statute, fifty state answers

There is no single federal sweepstakes law. What exists federally is postal and mail fraud regulation plus the Federal Trade Commission's general authority over unfair and deceptive practices. The operative rules are at state level, and they are not uniform.

Florida is the clearest published example and worth reading in full because it shows the shape of the obligation. Section 849.094 of the Florida Statutes defines a game promotion as a contest, game of chance, sweepstakes, or gift enterprise conducted in connection with and incidental to the sale of consumer products or services, in which the elements of chance and prize are present. Note what is absent from that definition: consideration. Florida regulates exactly the promotions where the payment element has been removed.

Under section 849.094(2) it is unlawful for an operator to rig or predetermine outcomes, to arbitrarily remove, disqualify, disallow, or reject any entry, to fail to award prizes offered, to circulate advertising material which is false, deceptive, or misleading, or to require an entry fee, payment, or proof of purchase as a condition of entering a game promotion.

The registration trigger is a dollar threshold. Where the total announced value of prizes offered is greater than $5,000, the operator must file a copy of the rules and a list of all prizes and prize categories with the Department of Agriculture and Consumer Services at least seven days before the promotion commences, accompanied by a $100 nonrefundable filing fee. The statute then says those rules may not thereafter be changed, modified, or altered. Above the same $5,000 threshold the operator must also establish a trust account with a balance sufficient to pay the total value of all prizes, or obtain a surety bond for the equivalent amount, filed at least seven days in advance.

Three operational consequences follow for research teams. First, the threshold is on announced prize value, not on spend, so five $1,200 prizes crosses it. Second, the seven-day advance filing is incompatible with the way most research studies get scheduled, which means the incentive design has to be locked before the recruitment brief. Third, the no-changes rule means you cannot quietly extend a draw because recruitment ran slow.

Other states impose their own registration, bonding, or disclosure regimes with different thresholds, and some have historically read consideration more broadly than the UK does, treating substantial time or effort as sufficient. That last point matters enormously for research: an interview is time and effort by definition. If you accept entries from multiple states, design to the strictest standard you are exposed to rather than the friendliest.

Banned outright, no harm required

Some prize practices are prohibited without any need to show that a consumer was actually misled. Schedule 20 of the UK Digital Markets, Competition and Consumers Act 2024, in force from 6 April 2025, lists commercial practices that are unfair in all circumstances. Four are directly relevant:

Paragraph 21 is the one research teams breach by accident. A study is cancelled, the recruitment stops, and nobody runs the draw. The prize was described in the recruitment email. That is the banned practice, and it does not matter that the study never happened.

The five research-specific traps

Customers-only draws. Restricting entry to paying customers ties the entry opportunity to a purchase. It is also the fastest way to guarantee a selection-biased sample. Open the draw and use screening to control who qualifies for the study.

Complete-to-enter. Wording an incentive as complete the interview to be entered into the draw makes completion a condition of entry. In the UK this is not payment under Schedule 2 on its face, but in several US states substantial time and effort has been treated as consideration. It also creates an incentive to finish fast rather than to answer well.

Employee and partner entries. If your own staff can enter, you have a fairness problem, an internal-control problem under provisions like Florida's prohibition on rigging, and a data quality problem. Exclude them explicitly in the rules.

Cross-border panels. A single global recruitment link routes entrants from jurisdictions with incompatible rules into one draw. Either geofence the draw or run separate, jurisdiction-specific promotions.

The unclaimed prize. Every rules document needs a claim window, a notification method, and a stated consequence of non-claim. Without one you are holding a prize you have promised to award and cannot lawfully keep quiet about.

The cost nobody prices: a draw changes who answers

This is the part that never appears in the budget conversation, and it is usually larger than the money saved.

Start with expected value. A $500 prize across 200 participants is worth $2.50 per person. A guaranteed $25 is worth $25. You are offering ten percent of the value, and you are asking each participant to price a one-in-two-hundred outcome in their head. People are famously bad at that, and they are bad at it in a way that is not random: sensitivity to low-probability, high-magnitude payoffs varies systematically between individuals. A draw therefore does not reduce your response rate evenly across the population. It shifts the composition of who says yes toward people who find lotteries attractive, and away from people who evaluate the offer as $2.50 of their time.

Then look at what the draw rewards. A guaranteed incentive pays for effort: everyone who completes gets the same amount, and the amount is visibly tied to the length of the session. A draw pays the same expected amount to a participant who gives you a considered thirty minutes and a participant who clicks through in ninety seconds. Effort and reward are fully decoupled. That is the exact incentive structure that produces satisficing, straightlining, and the low-effort response patterns covered in our guide to survey data quality.

So the honest comparison is not $500 against $5,000. It is $500 for a sample of unknown composition with a weakened effort incentive, against $5,000 for a sample whose selection you can reason about. If the research is going to inform a pricing decision or a roadmap commitment, the $4,500 is cheap.

What to run instead

Guaranteed micro-incentives. Lower the per-person amount rather than converting to a draw. A guaranteed $10 preserves the effort-reward link and the selection profile in a way a $500 draw does not.

Charity donation per completion. A fixed donation per completed interview removes the prize and chance elements entirely, which takes you out of promotional draw law altogether. It also works well with B2B participants whose employers prohibit accepting personal gifts.

Findings-sharing. Offering an anonymised summary of the results costs nothing and works unusually well for professional and B2B audiences. It is not a prize, so no draw rules apply.

Tiered guaranteed incentives. Pay more for harder-to-reach segments rather than paying everyone the same and topping up with a draw. This targets the budget where the incidence rate is actually hurting you.

If you do decide the draw is right, run it as a genuinely open promotion with a clearly publicised free entry route, and do not attach it to study completion at all. Enter everyone who was invited.

Writing the rules document

Whatever you run, write the rules before recruitment opens, because in Florida and similar regimes you cannot change them afterwards. A defensible rules document states: who is eligible and who is excluded; the exact geographic scope; the opening and closing dates and times with a time zone; the number, description and announced value of every prize; the free entry route and how to use it; the selection method and date; how winners will be notified; the claim window and what happens to unclaimed prizes; whether any tax liability falls on the winner; the promoter's full legal name and address; and how entrant personal data will be handled and deleted. Publish it at a stable URL and link it from every recruitment touchpoint, not just the final confirmation screen.

Running incentive-light research with Koji

The reason prize draws became standard in research operations is that traditional moderated research is expensive per participant in labour, not just in incentives. When a researcher has to schedule, moderate, transcribe and analyse each session, twenty interviews is a fortnight of work, and the incentive budget is the only line anyone can cut.

Koji removes that labour cost, which changes the whole calculation. The AI interviewer runs conversational voice or text interviews with every participant simultaneously, asks its own follow-up questions when an answer is thin, and produces the analysis automatically. Teams routinely field one hundred or two hundred conversational interviews in the time a traditional study would spend on scheduling. When the marginal cost of an additional interview collapses, guaranteed incentives fit the budget that previously forced a draw, and you keep the sample composition you wanted in the first place.

Three specifics matter for incentive design. First, structured questions let you screen cleanly at the top of the interview rather than screening by incentive eligibility. Koji supports six types: open_ended, scale, single_choice, multiple_choice, ranking, and yes_no. Use single_choice or yes_no for hard qualification criteria and let the AI move straight into open_ended probing for people who qualify, so nobody is paid for a session they were never eligible for. Second, because every interview is transcribed and quality-scored, you can see whether the incentive structure is producing thoughtful answers or ninety-second run-throughs, which is the feedback loop a prize draw denies you. Third, guaranteed incentives at a lower per-person value combined with a much larger sample generally produce better decisions than a small sample and a large prize.

Traditional survey tools such as SurveyMonkey, Typeform and Qualtrics leave the incentive problem entirely to you, because they capture answers and stop. The reason to look at an AI-native platform is that lowering the cost of the conversation is what makes the compliant incentive affordable.

Frequently asked questions

Is a prize draw for survey respondents legal?

Usually yes, provided nobody has to pay, purchase, or already be a paying customer in order to enter. A prize draw becomes an unlawful lottery when prize, chance and payment to enter are all present. Removing the payment element is what keeps the promotion lawful, which is why the free entry route and the no purchase necessary rule exist. Registration and bonding may still apply above certain prize values in some US states, and per se prohibitions such as failing to award an advertised prize apply regardless.

Does spending 30 minutes on an interview count as payment to enter?

Under UK law the definition of paying in Schedule 2 of the Gambling Act 2005 covers money, money's worth, and paying for goods or services at a price or rate which reflects the entry opportunity. Time and effort alone are not listed. Several US states take a broader view of consideration and have historically treated substantial time or effort as sufficient. If you run cross-border research, design to the stricter standard rather than the friendliest one, and avoid making study completion a condition of entry.

What are the four conditions of the UK free entry route?

Schedule 2 paragraph 8 requires all four together: every eligible individual has a genuine choice between paying and sending a communication; that communication route is neither more expensive nor less convenient than the paid route; the choice is publicised so it is likely to come to the attention of each individual who proposes to participate; and the prize allocation system does not differentiate between paid and free entrants. Failing any one of them collapses the exemption.

When do I have to register a prize draw in the United States?

There is no single federal registration. Florida requires operators of a game promotion with announced prizes over $5,000 to file the rules and prize list with the Department of Agriculture and Consumer Services at least seven days before launch, pay a $100 nonrefundable fee, and establish a trust account or surety bond covering the full prize value. Rules may not be changed after filing. Other states impose their own registration, bonding or disclosure regimes, so check every state from which you will accept entries.

Can I limit a research prize draw to existing customers?

You can, but it changes the analysis in two ways. Legally, tying the entry opportunity to being a paying customer is close to the link that the payment element is designed to capture. Methodologically, it guarantees a sample of people who already bought and did not churn, which cannot answer questions about non-adoption or loss. A cleaner design is to open the draw and use screener questions to control who qualifies for the study itself.

Are guaranteed incentives really better than a prize draw?

For most research, yes. A $500 draw across 200 participants is worth $2.50 per person in expected value against a $25 guaranteed payment, so you are offering ten percent of the value while asking participants to price a low-probability outcome. The draw also pays the same to a thoughtful thirty-minute respondent and a ninety-second speed-runner, which is the incentive structure that produces satisficing. AI-moderated platforms cut the per-interview labour cost enough that guaranteed micro-incentives usually fit the budget that previously forced the draw.
