FAIRBlackjack
Same contract and ~90% return — but its own prize table: wins here are frequent and small, almost every one pays ×2. The round payout is decided by the blockchain the moment you bet; the table reveals it with cards: score more than the dealer without going over 21.
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.
Rules at this table
A round is one contract spin (or a ×10/×100 batch in one bet). First the contract takes the bet and computes the payout, then the table deals cards to arrive at it: a winning round — your hand beats the dealer; blackjack — a big payout; a loss — a bust or a stronger dealer hand. “Hit” and “stand” change only the picture of the hand, not the payout — so the odds here are the same as at the wheel and the slots.
This game's prize table
Each game has its own table: here a prize lands in roughly 7.28% 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 17 |
| ×2.5 | 25,000 | 1 in 92 |
| ×5 | 50,000 | 1 in 344 |
| ×25 | 250,000 | 1 in 1,527 |
| ×250 | 2,500,000 | 1 in 13,745 |
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.
