Instant win games are sweepstakes where participants find out immediately whether they've won — a scratch card reveal, a spin-to-win wheel, a virtual prize drop. The immediate result gives people a reason to play, and daily play limits give them a reason to come back.
Instant win promotions take more planning than a single drawing. You need to decide how winners are determined, set up and document the prize pool and odds, manage prize inventory across the promotion period, and comply with the same sweepstakes laws that govern any chance promotion.
This guide covers the mechanics, math, and compliance behind running a successful instant win game.
How Instant Win Games Work
Instant wins reveal an outcome after a participant plays. Revup supports random odds, generated winning times, and winning codes. Choose the mechanism before configuring prizes and publishing the rules.
Example: Winning-Time Mechanics
Pre-seed winning moments
Before launch, the system randomly distributes winning moments across the entire promotion period. Each winning moment is associated with a specific prize from the prize pool.
Participant plays the game
A user interacts with the game mechanic — spinning a wheel, scratching a card, opening a digital envelope. The visual is for engagement; the outcome was determined by whether that moment is a winning moment.
System checks the clock
In a winning-times promotion, an eligible play can claim an available winning time once it has been reached. It does not need to match that timestamp exactly.
Result delivered instantly
Winner sees a winning reveal and receives instructions for claiming their prize. Non-winners see a 'try again' message and are encouraged to return.
The game visual doesn't determine the outcome
In a compliant instant win game, the spinning wheel or scratch card animation is purely visual. The server determines the outcome using the configured odds, winning times, or winning codes; the animation reveals that outcome. This is an important legal distinction — the visual entertainment element must never misrepresent the actual probability of winning.
Popular Instant Win Game Formats
Revup supports spin wheels (and spin the bottle), scratch cards, mystery boxes, and winning codes. Other formats need a custom build.
| Format | Best For | In Revup | Complexity |
|---|---|---|---|
| Spin-to-win wheel | Retail, ecommerce, event booths | Yes | Moderate |
| Digital scratch card | Mobile campaigns, email promotions | Yes | Low |
| Mystery box | Product drops, gift-style reveals | Yes | Low |
| Winning codes | Product packaging, in-store displays | Yes | Moderate |
| Prize drop / claw machine | Gamified brand experiences | No (custom build) | High |
| Match-to-win | Loyalty programs, repeat engagement | No (custom build) | Moderate |
Calculating Odds for Instant Win Games
Odds calculation for instant win games is more nuanced than for standard sweepstakes. In a single-prize drawing, each entry's odds are 1 divided by the total number of eligible entries. In an instant win game, odds depend on how many prizes there are at each level, how they're distributed, and how many plays occur.
The Basic Odds Formula
For a simple instant win game with a fixed number of prizes distributed evenly across the promotion:
- Odds per play = Total prizes ÷ Expected total plays
- Example: 100 prizes across an expected 50,000 plays = odds of about 1 in 500 per play
- Calculate this for each prize level; your rules should state the odds of winning each prize.
Time-Seeded, Random-Per-Play, and Winning Codes
There are three common approaches to determining instant win outcomes, and Revup supports all three:
- Time-seeded (pre-determined): Winning moments are randomly assigned to specific timestamps before the promotion starts. The first eligible person to play at or after each winning moment wins. This is common because the prize pool is fixed and the schedule can be documented before launch.
- Random-per-play: Each play triggers a random number generation with fixed probability. This approach is simpler to implement but harder to guarantee exact prize distribution — you might award all prizes early or have prizes left at the end.
- Winning codes: A set of codes is designated as winners in advance, for example codes printed on packaging. Entering a code reveals whether it wins.
Odds must be disclosed in your official rules
Disclose the odds of winning each prize in your official rules. When prizes are seeded in advance, odds depend on the number of plays, so state the number of prizes at each level and how they're distributed over the promotion period. Every play, whether it comes with a purchase or is free, must have the same odds.
Prize Pool Design and Distribution
A well-designed prize pool balances high-value anchor prizes with frequent smaller wins to keep players engaged.
Tiered Prize Structure
- Grand prize (1-3): High-value items that drive initial interest and promotion sharing. Examples: electronics, travel, large gift cards.
- Mid-tier prizes (10-50): Moderate-value items that keep excitement high. Examples: product bundles, branded merchandise, $50-$100 gift cards.
- Frequent wins (100-1,000+): Low-value prizes that create a high win rate. Examples: discount codes, free products, small gift cards, digital content.
Frequent small wins encourage repeat play
A higher overall win rate makes winning feel achievable. Many brands combine frequent small wins (discount codes, free items) with a few larger prizes that drive sharing. Count every prize's retail value when checking state filing thresholds.
Time Distribution Strategy
You don't have to distribute prizes evenly. Many schedules account for traffic patterns. Whatever you choose, set it before launch and describe it in your rules:
- Launch day surge: Allocate more prizes to the first 24-48 hours when traffic is highest. Early winners generate social proof.
- Mid-promotion maintenance: Steady prize distribution to maintain engagement during the middle period.
- End-of-promotion push: Reserve prizes for the final days to create urgency and a second traffic spike.
- Daily caps: Limit daily prize awards to prevent all prizes from being claimed on high-traffic days.
Legal Requirements for Instant Win Games
Instant win games are sweepstakes: winners are determined by chance, so consideration must be removed. If plays come with purchases, offer a free way to play with the same odds per play. All standard sweepstakes laws apply, plus disclosures specific to instant win formats.

Setting Up Your Instant Win Game
Instant Win Game Launch Process
Define prize pool and budget
Determine total prize value, number of tiers, and prize mix. Calculate expected play volume to set odds. Check New York and Florida filing thresholds.
Choose game mechanic
Select the visual format (wheel, scratch card, etc.) that fits your brand and campaign. Remember: the visual is entertainment — the algorithm determines outcomes.
Configure odds and time-seeding
Set winning moments across the promotion period. Distribute based on expected traffic patterns. Document the algorithm and seed data before launch.
Draft official rules
Include all standard sweepstakes requirements plus instant win-specific elements: mechanics, per-play odds, total prizes, and claim process.
Build and QA
Test all game states: winning reveal, losing reveal, prize claimed, promotion expired, ineligible player. Test the AMOE path. Verify rules link.
Launch and monitor
Track plays, wins, prize inventory, and claim rates in real time. Monitor for fraud patterns (rapid-fire plays, bot behavior, location spoofing).

Frequently Asked Questions
Can I limit the number of plays per person per day?
Yes. Many instant win promotions limit plays to one or a few per person per day. State this clearly in your official rules. Implement technical controls (cookies, account-based limits, IP monitoring) to enforce the limit, but don't rely solely on technical measures — document the rule.
What if prizes run out before the promotion ends?
Your official rules should address this scenario. Common approaches: end the instant win element early (announce that all instant win prizes have been claimed), or continue the game with a second-chance drawing for remaining participants.
Do I need to award all prizes?
Your rules should say what happens to prizes that aren't won or claimed, such as seeded prizes still available at the end or winners who don't complete the claim. Common approaches are leaving them unawarded or holding a second-chance drawing. Florida's game promotion law prohibits failing to award prizes offered, so have this clause reviewed.
Can an instant win game require a purchase?
Not without a free way to play. Requiring a purchase adds consideration and makes the game an illegal lottery. Plays can come with purchases if anyone can also play free, with the same odds per play for the same prizes. Selling plays directly, or a product that's a pretext for buying plays, can be illegal gambling even with a free method (People ex rel. Green v. Grewal, Cal. 2015). See our purchase sweepstakes guide for how free entry works alongside purchases.
