Diamonds
The return is about 90%, as in all FAIRDRUM games. This game has its own prize table: prizes are frequent and small, from ×1.5 for a pair to ×50 for five matching gems. A prize in roughly every third round; the contract computes the combination from the oracle's random number.
FAIRDRUMPowered by SolanaRound: bet 0.1 SOL + network and oracle fee 0.005 SOL (5% of the bet). The fee is charged once per round, so a larger round is cheaper.
The round's payout is determined by the contract at the moment of settlement, from the oracle's random number: the field only reveals it. A round is several 0.01 SOL stakes at once (ten in a 0.1 SOL round): the field shows the best of them, and the total for the whole round is on the line under the field. Each game has its own prize table (see below), and the average return is the same in all games. If something goes wrong, a message with a code appears under the field: errors and solutions. Details: how it works · fees.
How a round works
You press “Reveal gems” — the contract accepts the bet, gets a random number from the oracle and computes the payout from the table below. Five gems show it as a combination: a pair — ×1.5, two pairs — ×2, three of a kind — ×3, three and a pair — ×5, four — ×10, five of a kind — ×50. If all the gems are different, the round has no prize.
This game's prize table
Every game has its own table: here a prize lands in about 33.55% of spins. On top of the table, every game plays for the shared mini jackpot, jackpot and super jackpot, and "Again" gives a repeat spin paid by the prize bank. The table is written in the contract — the page only displays it. A single prize cannot exceed a quarter of the prize bank.
| Multiplier | Prize, SOL | Chance per spin |
|---|---|---|
| ×1.5 | 0.015 | 1 in 6 |
| ×2 | 0.02 | 1 in 10 |
| ×3 | 0.03 | 1 in 23 |
| ×5 | 0.05 | 1 in 60 |
| ×10 | 0.1 | 1 in 175 |
| ×50 | 0.5 | 1 in 994 |
Bets, the round fee and jackpots
A round is 0.1 to 1 SOL: that is 10 to 100 stakes of 0.01 SOL in one signature; the round's payout is shown as one total. For every round the network and the oracle charge a fixed 0.005 SOL, so a larger round is better value. Every bet tops up the shared pots: the prize bank, the jackpot, the mini jackpot and the super jackpot — the same ones the wheel plays for.
Winnings are credited to your game balance at once. Withdrawal has no project fee, documents or checks; it opens 12 hours after the last deposit. If a round gets stuck, for example the connection dropped, the "Finish the spin" button settles it without a new bet: the result is recorded on the blockchain and is not lost.
