Design the game
Define the player decision, risk structure, feature cadence and distinctive reason for the cabinet to exist.
All case studies
Game mathematics & interactive systems
Twenty-one cabinets. Not twenty-one coats of paint.
Koraaver Bookmakers includes a complete internal arcade of mechanically distinct cabinet games. Each begins with rules and probability, then becomes a persistent, animated and testable playable system.

The design problem
Variety has to survive beneath the artwork.
A cabinet portfolio can look broad while repeating one game underneath. This work takes the opposite approach: reel games, tracks, ladders, sealed picks, cluster grids, excavation, racing and push-your-luck structures are authored as separate rule systems.
Common infrastructure handles wallet state, persistence, committed outcomes and presentation conventions. The decision model and mathematics remain machine-specific.
From idea to playable evidence
Model the mathematics
Express symbol weighting, win evaluation, paytables, feature probabilities and payout behaviour as reproducible rules.
Simulate and challenge
Run large-spin calibration, deterministic acceptance cases and persistence tests before presentation can disguise a fault.
Realise the cabinet
Join the rules to state, animation, artwork, sound, wallet behaviour and refresh-safe committed outcomes.
Two different demonstrations
One compact risk game. One feature-led reel game.
The public routes deliberately expose only the selected cabinets. They do not open the wider campaign, wallet or arcade lobby.
Cabinet 01
Track the Cash
A 42-space press-your-luck loop. Blanks grow the pot, multipliers settle it and crosses destroy it. The interesting choice arrives after a successful build: collect now, or pay to risk the pot again.
- Fixed £100 demonstration stake
- Locally persistent £100,000 demo wallet
- Code-driven track movement and responsive audio
Cabinet 02
Shootout Super Spins
A five-reel, ten-line game with two persistent builders. Footballs strengthen the Shoot Out; rattles strengthen Super Spins; reducers can move either ladder backwards before Scatters hand the decision to reel five.
- Fixed, illuminated £10 demonstration stake
- Shoot Out and Super Spins feature modes
- Existing cabinet artwork and three-state music system
Probability modelling
Weighted symbols, fixed paths, win evaluation and feature distributions are explicit data rather than animation-driven outcomes.
Simulation & tests
Calibration scripts and deterministic acceptance cases challenge game behaviour separately from the visual cabinet.
Shared architecture
Common wallet, persistence and presentation principles support many game types without forcing them into one mechanic.
Demonstration boundary
Playable product-design evidence—not real-money gambling.
The live cabinets use resettable demonstration credits. They accept no deposits, permit no withdrawals, award no prizes and have no monetary value. They demonstrate systems design, mathematical implementation and interactive realisation; they do not claim regulatory certification.
