Plinko

The ball takes 12 independent left/right bounces, each one a crypto.randomInt(2) draw, so the bucket it lands in follows a Binomial(12, ½) distribution — the middle buckets are genuinely far more likely than the edges, exactly like a real peg board. The board on screen isn't decoration either: every peg the ball is drawn passing sits at the exact row and column its path implies.

The payout table is fixed, but the RTP is not assumed to be 99% — it is computed exactly by weighting every bucket's multiplier by its true binomial probability, and that computed figure is what gets published.

Dropping more than one ball fires that many independent bets at once — each is staked, settled and paid the instant it is placed, the same as a single drop. The board just holds the reveal back until that ball's own fall finishes, so a burst of fifty is fifty ordinary bets that happen to land at a glance rather than one bet split fifty ways.

This board: 98.99% RTP.
