Fair Play and Provably Fair Dice

1. Provably fair dice

• Dice are rolled on our server, never on your phone, using algorithm hmac-sha256-v1.
• When a match is created the server picks a secret seed and shows you its SHA-256 fingerprint before the first roll, so the dice are locked in and cannot be changed mid-game.
• Your own client seed (random, or one you choose) and the match id are mixed in, so we cannot know the dice before players sit down.
• After the match the secret seed is revealed. Anyone can check that it matches the fingerprint and recompute every roll, bots' rolls included.
• There is no admin tool that sets dice or outcomes. Matches created before the provably fair system went live (13 October 2026) cannot be verified this way.

The exact algorithm is published on the verifier page.

2. Where bots play

• Bots always carry a BOT label and a bot name.
• Practice games are against bots only and use tokens, never money.
• In a free 4-player private room the host may fill empty seats with bots. Never in a cash room.
• At House tables you play against Arena House (Bot), our clearly labelled House bot, for a published multiplier (currently 1.7x at a 2-seat table; multiplier = (1 - house edge) x seats in play, house edge 15 %). The bot uses the same fair dice and plays honestly at its stated difficulty.
• Bots never play in real-money matches between players: cash quick matches, cash private rooms and cash tournaments are humans only.
• Auto mode, if you choose it, lets a fair bot play your own turns for you; it never sees hidden information and uses the same dice.

3. Our revenue is disclosed

In player-versus-player cash matches we earn only the platform fee shown before you join; we never play against you and outcomes are never adjusted. At House tables the house edge is built into the published multiplier. See the Terms of Service for every fee.

4. What is not allowed

• collusion: teaming up, sharing information, signalling in chat, passing chips or deliberately losing;
• multi-accounting, account sharing, or playing on someone else's account;
• bots, scripts, auto-clickers, modified apps or exploiting bugs;
• sharing links or phone numbers in match chat to arrange deals off the platform;
• abusing bonuses, referrals, gifts or the token conversion.

5. How we check

Every roll, move and timing is logged. Cash-match chat is kept (also when deleted) and attempts to share links or numbers are recorded. We flag accounts sharing devices, ID or payout numbers, players who meet repeatedly with one-sided results, and unusual money movements. Flags are reviewed by people, not decided by a machine alone.

6. Sanctions

Depending on how serious it is: a warning, chat restrictions, voided matches, removal of winnings, bonus or tokens gained unfairly, suspension, or closure of all linked accounts. Illegal activity may be reported to the authorities. You can challenge a decision through Complaints and Disputes.

7. Report cheating

Use the report button in a match or Support, with the match id if you have it, or email [email protected]. Reports are confidential.
