Plinko is the simplest game in any crypto casino's Originals lobby, and that simplicity is why it is worth understanding properly. There are no paylines, no bonus rounds and no decisions mid-round. You choose a bet, a number of rows and a risk level; a ball drops from the top of a triangular peg board; every peg sends it left or right; and the bucket it lands in at the bottom pays a fixed multiple of your bet. That is the whole game.
The board
A Plinko board with n rows has n+1 buckets. The top row has three pegs, each row below has one more, and the ball starts centred above the top row. At each row it hits a peg and deflects half a bucket-width left or right with equal probability. After n deflections it has moved a net distance equal to the number of "rights" minus the number of "lefts", which puts it in bucket k where k is the count of rights. Casinos offer every row count from 8 to 16.
Risk levels
Risk does not change the physics; it changes the paytable. Low risk keeps every bucket between 0.5× and 16×. Medium drops the centre as far as 0.2× and lifts the corners to 110×. High pays 0.2× on most of the middle and 1000× on the 16-row corners. All three return about 99% of stakes over time.
| Risk (16 rows) | Top | Lowest | Drops ≥1× | Std dev / bet | RTP |
|---|---|---|---|---|---|
| Low | 16× | 0.5× | 80.4% | 0.33 | 99.00% |
| Medium | 110× | 0.3× | 45.4% | 1.47 | 98.99% |
| High | 1000× | 0.2× | 21.0% | 6.57 | 98.98% |
Betting and settlement
You enter a stake – usually from $0.01 equivalent in any supported crypto – and press Bet. The ball animates down and your balance updates the moment it lands; at most brands you can drop several balls at once and let them overlap. Auto-bet drops a set number of balls at a set stake and can stop automatically on a profit or loss limit, which is the one genuinely useful control the game offers.
Provably fair
At Stake, Shuffle, Rainbet and the other brands we list, the path of every ball is derived from a server seed (hashed and shown to you before the bet), a client seed you can change, and a nonce that increments with each bet. After the fact you can reveal the server seed and verify that the published hash matches and that the path was computed honestly. The casino cannot alter a result after seeing your bet, and you can audit any drop you like.
What the rules do not include
There is no skill element, no timing, no way to influence where the ball goes, and no "hot" or "cold" board. Each drop is independent. The only choices with real consequences are bet size relative to bankroll, risk level, and how long you play – which is why our strategy guide is mostly about those three things.
