Engine validation
Compliance and bet tiers
Engine validates every title before release: the base mode must pass seven compliance checks, then each bet tier tests the game against risk limits.
- Cross-mode RTP consistency0.17%
RTP across all modes stays within the allowed variance. Expected ≤ 0.50%.
- Base mode cost1.00x
The cheapest mode is the 1.0x base game. Expected = 1.00x.
- Base mode standard deviation15.52x
Base-game standard deviation stays within limits. Expected ≥ 0.60x.
- Bet level validator500max_1cent
A valid three-star bet-level template exists. Expected: valid template.
- RTP range96.70%
Return to player sits inside the allowed band. Expected 90.0% to 96.70%.
- Cost multiplier1x
A mode’s cost multiplier stays under the cap. Expected ≤ 50,000x.
- Max payout multiplier25,000x
The largest win stays under the cap. Expected ≤ 1,000,000x.
Bet template 100max_1cent
Every constraint within limits.
Bet template 500max_1cent
Every constraint within limits.
When a mode exceeds a tier’s limit, Engine lowers that tier’s caps instead of blocking the game. Values over a limit come from high-cost modes, noted in the table below.
