Calculators
Five small calculators for the numbers people argue about in chat: Mines and Plinko odds, dice multipliers, what an RTP version costs, and where a bonus hunt breaks even. Each page shows the formula and a worked example under the calculator.
- Bonus hunt calculatorBonus hunt calculator: start cost and bet sizes give the break-even average, and each win you type updates the live average and what the rest must pay.
- Dice calculatorDice calculator: turn a win chance into the multiplier it pays at a given RTP, or a multiplier into its win chance, with roll-under and roll-over targets.
- Mines calculatorMines calculator for a 5x5 board: pick the mines and the safe picks to see your odds of getting through and the fair and RTP multipliers. Formula on the page.
- Plinko calculatorPlinko calculator for boards of 8 up to 16 rows: the chance of every bucket, and with the board multipliers typed in, the return per dollar and the house edge.
- RTP calculatorRTP calculator: bet size times spins gives the total wagered, and each RTP version shows its expected loss next to the others, in dollars.
Everything runs on your device. Nothing you type gets sent anywhere, so you can paste in a real board or a real hunt. None of them predict a result. They show odds and averages, and a single round or session can land anywhere.
