How to play

Choose the number of rows, from 8 to 16, and a risk level: Low, Medium or High. Set your stake and drop a ball. At every row it bounces left or right until it lands in one of the bins along the bottom, and the bin's multiplier is your payout. The centre bins are hit most often and pay the least; the edges are rare and pay the most.

Rules at a glance

• 8 to 16 rows (12 by default) and three risk levels (Medium by default).
• Each ball is its own stake, decided the moment it lands.
• A 1× bin returns the stake; bins below 1× pay part of it back.
• No per-round cap: the 1,000× bin on the 16-row High table pays 1,000 times the stake.

Odds and payouts

A ball that bounces right k times out of n rows lands in bin k, with a probability of C(n, k) divided by 2 to the power n. The default set of 27 tables averages a 99.0 percent return; High tables move the money from the middle to the edges, Low tables keep it flat.

Provably fair

Every row is one draw from the server seed, your client seed and the row's nonce: an even draw sends the ball left, an odd one right. The path is fixed before the animation starts. 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

Rows and risk mainly change the shape of the ride. Low risk on 8 rows is a gentle grind; High risk on 16 rows is a lottery with a 1,000× jackpot and a lot of small bins in between.
