A prize table is a commercial instrument disguised as a spreadsheet. Move the top prize up and the low-tier win frequency down, and the same payout percentage produces a game that feels dead in the hand. Players stop returning long before the sales report shows it.
Most operators inherit prize structures from a template or a vendor library and never model what the shape of the ladder is doing to repeat purchase.
Prize structures are built from the player experience backwards. Target payout ratio and margin set the envelope, then win frequency at the low tiers, the mid-tier worth-going-back-for band and the headline prize are tuned inside it. Every variant is modelled so you can see the trade explicitly rather than argue about it, and the working is handed over in a form a regulator or auditor can re-run.
- Full prize structure and odds table per game, with the modelling workbook
- Win-pattern and play-mechanic design for instant games
- Draw game matrix design, including rollover and jackpot cap behaviour
- Payout, margin and break-even sensitivity across sell-through scenarios
- A mathematics summary written for regulator and audit review
There is no single right answer. It depends on price point, competing gambling products in your market, retailer commission and what your good-causes obligation requires. What matters is that the number is chosen deliberately and the ladder shape designed around it, rather than inherited.
The workbook is built to be re-run independently, with assumptions stated on the face of it. Where your jurisdiction requires third-party certification, the output is structured for a testing laboratory to pick up directly.
Part of our lottery consulting services.
Every lottery game is a promise expressed in mathematics: this is how often you win, this is what you can win, this is what it costs. Get the matrix and the prize structure right and a game can carry a portfolio for a decade; get them wrong and even heavy marketing cannot save it. Lotto Edge Consulting designs and reviews the game mechanics and odds beneath draw and instant games, balancing player appeal, jackpot behaviour and operator margin.
What game mechanics and odds covers
- Matrix design — the number field and draw format that shapes jackpot frequency, roll behaviour and headline odds.
- Prize structure and payout — the tiers, win frequency and payout ratio that make a game feel rewarding while protecting margin.
- Jackpot dynamics — roll rates, caps, guarantees and the behaviour that drives excitement and sales spikes.
- Instant-win mechanics — play styles, reveal mechanics and the odds tables behind them.
- Modelling and validation — simulating the game before it launches so there are no surprises in the field.
How we approach it
We model the game before it ever reaches a player. That means simulating jackpot frequency and roll behaviour, stress-testing the prize table against sales scenarios, and checking that the headline odds and the felt experience of playing actually match. A game that looks generous on paper but rarely pays a meaningful mid-tier prize will disappoint; a game that pays too freely will not sustain its jackpot or its margin. The craft is in the balance, and the balance is in the numbers.
Typical deliverables
- Game matrix and format design
- Prize structure and odds tables
- Jackpot and roll modelling
- Simulation results and scenario analysis
- Game design documentation ready for your platform or print partner
Who this is for
Operators launching a new draw or instant game, refreshing an underperforming one, or seeking an independent review of a design a vendor has proposed.
Common questions
Can you review a game a vendor has already designed?
Yes. An independent review of a vendor’s proposed matrix and prize structure often surfaces margin or player-experience issues before you commit.
Do you provide the odds tables and documentation?
Yes — full matrix, prize tiers, odds tables and simulation results, documented so your platform or print partner can implement them directly.
How is this different from the scratch operations service?
Game mechanics and odds is the design of the game itself; scratch lottery operations is the operational programme around it. Most engagements touch both.
