Bitcoin dice is the original provably fair crypto casino game — a simple number prediction mechanic where players bet that a randomly generated number will be above or below a chosen threshold. The player selects a target number (e.g., "roll over 50.01"), and the result is determined by a cryptographic random number generator that can be verified by the player after each roll. The house edge in Bitcoin dice is set by the operator — typically 1% (resulting in a win probability and payout that multiply to 0.99). Example: roll over 50 (49.5% win probability) pays 1.9802× on a 1% house edge site. Players can adjust the threshold — lower win probability, higher payout (up to 98× or beyond on very low-probability rolls). Bitcoin dice was the first provably fair game category — predating live dealer crypto casinos — and remains the simplest way to play verifiably fair crypto gambling. BC.Game pioneered the genre before it became an industry standard. This guide covers how Bitcoin dice works, the house edge mathematics, adjustable strategies, and which Bitcoin casino sites offer the best dice experience.

Bitcoin dice is a provably fair crypto casino game where players predict whether a randomly generated number will be above or below a chosen threshold. The result is cryptographically verifiable by the player. It is the original provably fair game category.
Typically 1% — set by the operator. Payout for any target: (0.99) ÷ WinProbability. The house edge is identical regardless of which threshold you choose — adjusting the target changes payout and probability but not the house edge.
Before play: the server seed is hashed and displayed. Player generates or enters a client seed. The roll result is determined by combining both seeds with a nonce. After play: the server seed is revealed. Player can independently verify: Hash(ServerSeed) = the hash shown before play, and the result matches the published algorithm. This proves the casino could not have manipulated the outcome.
Not in terms of house edge — Bitcoin dice is typically 1% vs European roulette's 2.70%, but dice IS better in that regard. Bitcoin dice offers provably fair verification that live dealer roulette cannot. Choose dice for verifiability; choose live dealer for lower house edge (in the case of blackjack at 0.44%).
BC.Game has the most developed provably fair originals library including Bitcoin dice, crash, and limbo. It also offers a full Evolution live casino alongside the provably fair games.
