Crypto casino tools and calculators

Bonus value calculator

Turn a headline offer into a number. Enter the deposit, match, wagering multiple, and house edge, and see what the bonus is actually worth once you have cleared it.

Open tool

Mines calculator

Exact combinatorial odds: the probability of surviving each safe tile, the mathematically fair multiplier, and what the operator actually pays after its edge.

Open tool

Limbo calculator

Convert any target multiplier into its true win chance, then compare the fair payout against the house-edge payout so you can see exactly what the margin costs.

Open tool

Crash session simulator

Play the same crash session 2,000 times at your stake, cash-out point, and house edge. See the expected cost, how often a session finishes ahead, and how often the balance runs out.

Open tool

Provably fair verifier

Reproduce the HMAC-SHA256 result from a revealed server seed, client seed, nonce, and cursor. Runs entirely in your browser — nothing is transmitted.

Two coin-specific calculators live with their rankings: the USDT withdrawal-fee calculator in our USDT casino comparison, and the Ethereum gas calculator alongside the best Ethereum casinos. For the fees casinos actually publish, see our withdrawal fee comparison by casino and network.

What these tools cannot do.They describe the mathematics of the games accurately. They do not predict outcomes, cannot identify a winning strategy, and cannot change the house edge — which applies to every bet regardless of what any calculator says. 18+ only.
