How to play

Pick between one and ten numbers on the 40-number board, choose a risk level (Classic, Low, Medium or High), set your stake and play. Ten numbers are drawn. Your payout depends on how many of your picks were drawn, read off the pay table for your pick count and risk level.

Rules at a glance

• 40 numbers, 10 drawn, 1 to 10 picks.
• Four pay tables per pick count: Classic, Low, Medium and High.
• A 1× cell returns the stake; cells below 1× pay part of it back; an empty cell pays nothing.
• The most one bet can pay is 25,000 SC at the default limit.

Odds and payouts

With p picks the chance of exactly h hits is C(10, h) times C(30, p − h) divided by C(40, p): one pick hits a quarter of the time, three of three about 1.2 percent, and all ten of ten about once in 848 million draws. The default tables average 98.0 percent across every pick count and risk level, with the top cells reaching 1,000×.

Provably fair

Ten draws from the server seed, your client seed and nonces 0 to 9 pick the drawn numbers one by one from those not yet drawn, so every set of ten is equally likely. 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

Fewer picks on the Classic or Low tables pay small and often; ten picks on High is a jackpot hunt with many blanks. The edge is nearly the same on every table, so choose the one that fits the session you want.
