How do you budget prizes for a promotion or in-store game?

To budget prizes for a promotion, estimate how many plays you expect, list each prize with its unit cost and chance of winning, and calculate the expected prize cost per play as the sum of chance × unit cost. Multiply by expected plays to get the monthly budget, then add daily caps on expensive prizes and make most prizes valid on the next visit so they also generate sales.

Why do prize promotions go over budget?

Most promotions that lose money were planned from the prize list instead of the numbers. An owner picks attractive prizes, guesses the odds and discovers at the end of the month that far more people played, or won, than expected. Others set odds so low that nobody wins, and the game dies after a week.

A prize budget fixes both problems. It tells you what each play costs on average, how many plays you can afford, and which prizes to cap. It also lets you compare a game with other marketing spend, such as an ad campaign or a discount, on the same basis.

What is the formula for expected prize cost?

The expected prize cost per play is the sum, for every prize, of its chance of winning multiplied by its unit cost. A losing outcome (“try again next time”) costs nothing, so it lowers the average without adding any prize cost.

• Expected cost per play = (chance of prize A × cost of A) + (chance of B × cost of B) + …
• Monthly prize budget = expected cost per play × expected plays per month.
• Cost per visit = monthly prize budget ÷ visits in the month (useful when not every visitor plays).
• Unit cost means what the prize costs you: food cost for a dessert, purchase cost for a product, the discount actually used for a voucher.

Estimate plays honestly

Plays depend on how many customers see the QR and how well staff mention it. Start with a cautious estimate, for example a fraction of your daily transactions, and correct it after the first week with real numbers.

What does a worked prize budget look like?

Here is an illustrative example for a café expecting 1,500 plays a month. The numbers are placeholders to show the method, not a recommended mix. Run your own version in the free prize budget planner, which calculates cost per play and per visit and lets you download the plan.

How do caps and limits protect the budget?

Odds describe the average; caps protect you from bad luck. Without caps, three gift boxes could be won on the first morning. With caps, the game automatically falls back to smaller prizes once the limit is reached.

1. Set a daily cap on every prize above a small cost, and a monthly cap on the most expensive one.
2. Limit plays per customer, for example one per day per phone number, to stop abuse.
3. Add an expiry date to every prize, such as 14 or 30 days, so liabilities do not pile up.
4. Protect wins with a unique code that staff validate once at the counter.
5. Review the numbers weekly and adjust odds rather than stopping the game abruptly.

Why are next-visit prizes the smartest choice?

A prize valid on the next visit does two jobs. It rewards the player, and it brings them back, when they usually buy something else. In the example above, a customer who returns for a free pastry often orders a drink with it. Part of the prize cost is paid back by that sale, and some winners never redeem, which lowers the real cost further.

Instant discounts on today’s bill do the opposite: they reduce the margin of a sale that was already happening. For the trade-offs between reward types, read discount versus free gift: which reward works better.

Which game for which budget?

A spin wheel shows every prize and suits a mix of many small and a few big prizes; the spin-the-wheel marketing guide covers wheel design. A scratch card hides the result and works well with simple odds; see scratch card marketing ideas.

What rules should you check before launching?

• Some promotions or prize draws may need a permit or written rules from the local authority; check before launching, especially for large prizes.
• Publish clear terms: validity, one prize per customer per day, no cash alternative.
• Never link prizes to Google reviews. Give the game to every customer for the visit, then invite everyone, optionally, to leave an honest review.
• Keep a record of winners and redemptions in case of questions.

How does Dawwerni handle prize budgets?

On this platform you set each prize, its odds and its quantity, so the budget you planned is the budget the game follows. Customers scan a QR and play a short game such as a spin wheel, scratch card or mystery doors with no app to download. Each win receives a unique code verified at the counter, play limits reduce abuse, and prizes are usually valid on the next visit. The dashboard shows plays, wins and redemptions so you can compare real cost with your plan. You can browse the games catalogue or watch the 3-minute overview.
