Place your bet, pick a board of 8 to 16 rows and a risk level — Low, Medium, High or Degen — 36 boards in all, and drop the ball. The ball bounces down the pegs into a bin; each bin pays the multiple of your bet shown on it, from 0.15× on the centre bins of the calmest boards up to 1,000× on the edge of the 16-row High board. On Degen boards only the outer three bins on each side pay — up to 7,464.04× on the 16-row board — and every inner bin is a 0× bomb that pays nothing.
Total RTP is 98.98% to 99.00% on every board, the jar included. The maximum win is 10,000× your bet.
Every bet you place is poured into the glass jar beside the board too: the jar fills by the money staked and bursts once it has gathered 250× the first drop that started it (the reference). The drop that fills the jar also draws its award, which is added to that drop's normal board win.
The jar's awards are drawn when it bursts: 1× the reference (77.40% of bursts), 2× (10.05%), 3× (7.50%), 10× (4.00%), 25× (0.80%), 100× (0.20%) and 500× (0.05%). On average a burst pays 2.25× the reference. What is left of a drop after a burst starts the next jar at the same reference, so no staked money is wasted.
Every drop is decided on the server before it is shown and can be checked on the fairness page; the jar's fill and its award when it bursts are decided on the server too, and shown on the drop.
