Crypto Dice is the purest provably-fair game ever built — a single roll from 0.00 to 99.99 against a target you choose. Set your number, pick Roll Under or Roll Over, and the multiplier auto-calculates from win probability. It is the same game powering high-volume Bitcoin dice sites and the favorite tool of bankroll-management strategists.

• Pick a target (2–98): Lower win chance = higher multiplier. A 2% chance pays roughly 49.5×; a 95% chance pays about 1.04×.
• Roll Under or Over: Bet the result lands below or above your target — both modes share the same 99% RTP.
• Martingale-friendly: Use our free Dice to safely test Martingale, Paroli, D'Alembert and Fibonacci strategies before staking real crypto.

Multiplier formula: 99 ÷ win-chance%. Every roll is independent — no streaks, no memory, no patterns. Just clean math, the way provably-fair Bitcoin dice should be.

Limbo is the high-multiplier sibling of Crash — except instead of cashing out before a rocket explodes, you pre-set the multiplier you want to beat. Enter a target like 2×, 10× or 1,000×, hit Take Off, and watch the crash point reveal in seconds. Beat it and you win your stake × target; fall short and you lose the round.

• Set any target: From 1.01× up to 1,000,000× — the higher you aim, the rarer the win.
• Instant rounds: Limbo is the fastest casino game on the market. Perfect for auto-betting and high-volume strategy testing.
• Hunt the moonshot: Chase 100×, 500× or four-figure multipliers — the same way high-volume players hunt their famous big-win clips.

Win probability = 99 ÷ target multiplier. A 2× target wins ~49.5% of rounds; a 100× target wins ~0.99%. House edge stays constant at 1% regardless of target.

Mines is the crypto casino take on Minesweeper — a 5×5 grid hides mines and gems. Choose how many mines to seed (1 to 24), then reveal tiles one at a time. Every safe gem multiplies your bet; hit a mine and you lose the round. Cash out any time to lock in your multiplier.

• Pick your mine count: 1 mine = long, low-variance runs. 24 mines = single-tile lottery with eye-watering multipliers on a lucky pick.
• Cash out smart: The multiplier curve steepens with every safe tile — knowing when to lock in is the entire game.
• Skill meets math: Unlike pure RNG games, Mines rewards disciplined cashout strategy — making it a favorite for bankroll-grinding crypto players.

Multiplier formula: 0.99 × C(25, picks) ÷ C(25 − mines, picks). Each pick is conditional on the remaining safe tiles, so the multiplier accelerates as the board thins out.
