Drop the ball through 12 rows of pegs. Where it lands pays the multiplier. Edges = jackpot. Middle = tax.
| Slot 1 (edge) | 110× your bet |
| Slot 2 (edge) | 41× your bet |
| Slot 3 (mid) | 10× your bet |
| Slot 4 (mid) | 5× your bet |
| Slot 5 (middle) | 3× your bet |
| Slot 6 (middle) | 1.5× your bet |
| Slot 7 (middle) | 1× your bet |
| Slot 8 (middle) | 0.5× your bet |
| Slot 9 (middle) | 1× your bet |
| Slot 10 (mid) | 1.5× your bet |
| Slot 11 (mid) | 3× your bet |
| Slot 12 (edge) | 5× your bet |
| Slot 13 (edge) | 10× your bet |
| Edges are rarer (probability ~0.02%) but pay 110× — middle slots hit ~25% of the time but pay back less than your bet. House edge ~3% over millions of drops. | |
Plinko drops a ball through a pegboard; the ball ricochets randomly and lands in one of several payout buckets at the bottom. Center buckets pay small multipliers; edge buckets pay large multipliers. The ball's distribution is a discrete binomial — bell-curve shaped — so center hits dominate. House edge of ~1% in well-calibrated implementations.
Choose a row count (8-16 typical) and "risk" level (low/medium/high). Higher risk levels widen the multiplier range (edge buckets pay more, center buckets pay less). Drop the ball; it bounces left or right at each peg with ~50% probability; it lands in a bucket and pays your bet × that bucket's multiplier.
Like other variance-shifting games, every risk + row combination has the same expected loss (~1%). Choose row count and risk to match desired variance: 8 rows / low risk for frequent small wins; 16 rows / high risk for occasional 1000x hits with mostly losses. No play strategy exists beyond stake size and quitting discipline.
With N rows, the ball follows a binomial(N, 0.5) distribution. The probability of landing in bucket k (counting from one edge) is C(N, k) / 2^N. For 16 rows, edge buckets have probability 1/65536 each, while the center bucket has probability C(16,8)/2^16 ≈ 19.6%. Multipliers are tuned so that sum(probability × multiplier) ≈ 0.99 across all buckets. Edge buckets in 16-row high-risk mode pay 1000x, but you'd need to play 65,536 rounds to expect one hit.
Plinko comes from the U.S. game show "The Price Is Right" (1983), where contestants drop chips down a vertical pegboard. Crypto casinos adapted it to a multi-bet, multi-bucket version in the late 2010s.
| Bet | Payout | Notes |
|---|---|---|
| 16 rows, low risk, center | 0.5x | Most common |
| 16 rows, low risk, edge | 16x | Rare |
| 16 rows, high risk, center | 0.2x | Most common, you lose 80% |
| 16 rows, high risk, edge | 1000x | Once per 65,536 drops |
