FAIRHi-Lo
Same contract and ~90% return — but its own prize table: frequent ×2–×4, and a long streak pays up to ×1,500. Guess whether the next card is higher or lower, but the streak length and the round payout were decided by the blockchain the moment you bet.
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 “New streak” — the contract takes the bet and computes the payout. Then you guess cards: in a winning round the streak runs exactly to its amount and the win is credited automatically; in a losing round one of the first cards goes against you. Your taps change only the picture of the streak, not the payout — 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 2.90% 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 |
|---|---|---|
| ×2 | 20,000 | 1 in 53 |
| ×4 | 40,000 | 1 in 157 |
| ×8 | 80,000 | 1 in 383 |
| ×30 | 300,000 | 1 in 1,150 |
| ×150 | 1,500,000 | 1 in 3,832 |
| ×1,500 | 15,000,000 | 1 in 34,492 |
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.
