Game rules
Last updated: September 2026
Trondice is a range-based dice game settled with a 1% house edge. These are the exact rules.
How a roll works
- Pick a range on the 0.00–100.00 line, for example 50.00 – 70.00.
- The server produces a roll using a committed seed and your client seed (see below).
- You win if the roll lands inside your range: low ≤ roll < high.
- Win chance (%) = high − low.
- Payout multiplier = 99 ÷ (high − low), i.e. stake × 99 ÷ win chance.
Example: a 20% range pays 4.95× (99 ÷ 20). Win chances range from 0.01% to 95%, and the minimum and maximum stake are shown in the bet panel.
Provably fair seeds
- At the start of a round the house generates a random 32-byte server seed and publishes only its SHA-256 hash (the commitment).
- You choose a client seed. Each roll uses an increasing nonce (0, 1, 2, …).
- The roll is HMAC_SHA256(serverSeed, “clientSeed:nonce:trondice”); the first 8 hex characters are read as an integer and taken modulo 10,000.
- The raw server seed is revealed when the round ends (after 500 rolls, or when you change your client seed), so every roll can be recomputed.
