Diamonds by Stakester Originals

How to play

Set a stake and deal. Five gems appear, each one of seven types, and the game reads them as a hand: pair, two pair, three of a kind, full house, four of a kind or five of a kind. Only the counts matter, never the colours or the order. The hand's multiplier times your stake is the payout.

Rules at a glance

• Five gems, seven types, drawn with replacement.
• Five of a kind pays 50×, four of a kind 4.8×, a full house 4×, three of a kind 3×, two pair 2×, a pair 0.1×, and no hand pays nothing.
• One stake, decided at once; the most one bet can pay is 25,000 SC at the default limit.

Odds and payouts

There are 16,807 equally likely results. Half of all deals are a pair (49.98 percent), which pays a tenth of the stake back; two pair comes 18.7 percent of the time, three of a kind 12.5 percent, a full house 2.5 percent, four of a kind 1.25 percent and five of a kind 0.04 percent, once in 2,401 deals. The default pay list returns 98.0 percent.

Provably fair

Five draws from the server seed, your client seed and nonces 0 to 4 give the five gems. The server seed is committed by its hash before you stake and revealed when the round closes, so you can recompute the result and check that the hash matches. The Fairness panel inside the game shows the seeds and the formula. In the free demo the server seed is generated in your own browser, so the check is a demonstration rather than independent proof; at a casino the game service holds the seed.

Playing it well

Diamonds has no decisions after the stake, so bankroll is everything. Expect long runs of pairs and no-hands between the two-pair and three-of-a-kind wins that carry the return, and size the stake for that.
