FAIRMines
Same contract and ~90% return — but its own prize table: mid-size prizes from ×3 to ×2,500. The round payout is decided by the blockchain the moment you bet, and the 5×5 board reveals it: the further the cells go, the bigger the tier.
The contract determines the round payout the moment you bet — just like the wheel: the board only reveals it. Each game has its own prize table (see below), while the average ~90% return is the same in every game. Details: odds · how it works.
How a round works
Press “Start round” — the contract takes the bet and has already decided the payout. Then you open cells: in a winning round there are exactly enough safe cells to reach its amount, and the win is credited automatically; in a losing round one of the first cells is a mine. Which cells you tap doesn't matter: it's a picture, not a choice, so the odds are the same as at the wheel.
This game's prize table
Each game has its own table: here a prize lands in roughly 1.49% of spins. On top of the table, every game also plays the shared mini jackpot, jackpot and super jackpot, and “Again” grants a free repeat. The table is baked into the contract — the page merely displays it.
| Multiplier | Tokens | Chance per spin |
|---|---|---|
| ×3 | 30,000 | 1 in 112 |
| ×6 | 60,000 | 1 in 268 |
| ×15 | 150,000 | 1 in 669 |
| ×50 | 500,000 | 1 in 1,673 |
| ×400 | 4,000,000 | 1 in 7,435 |
| ×2,500 | 25,000,000 | 1 in 66,912 |
Stakes, the free spin and the jackpots
A round's stake is 10,000 FAIRDRUM per spin; the ×10 and ×100 buttons gather a batch of spins into one bet and one signature, and the batch's payout is shown as one total. The weekly free spin works here too: until it is spent, the first round runs without a stake. Every paid spin tops up the shared pots: part goes to the prize fund, part to the jackpot and the super jackpot — the very same ones the wheel plays out.
Winnings are credited to the game balance immediately, and you can withdraw them in your account at any time — no documents or checks. If a spin stalls, for example the connection dropped, the "Finish the spin" button settles it without a new stake: the result is already written on the blockchain and cannot be lost. The history of rounds on this device is collected in the player account.
