Plinko Probability and Multiplier Calculator
This Plinko multiplier calculator is simple to use: choose the rows, the risk level and your stake, and it shows how likely each slot is and what it would pay. It uses the same left-or-right probability as the real board, so the numbers match how the ball actually falls.
How the Calculator Works
The idea behind Plinko probability is simple counting. For a board with n rows, the calculator counts how many different paths lead to each slot, then divides that number by the total number of possible paths, which is 2 to the power n, because the ball makes a left-or-right choice at every row. A slot reached by many paths is hit often, and a slot reached by one path is hit rarely. This pattern has a name: the binomial distribution. Finally, multiplying each slot's probability by its multiplier and adding all the results together gives the RTP.
Probability of Each Slot at 8 Rows
These Plinko odds show how often the ball lands in each of the 9 slots on an 8-row board, out of 256 equally likely paths.
| Slot | Paths | Probability |
|---|---|---|
| 1 | 1 | 0.39% |
| 2 | 8 | 3.13% |
| 3 | 28 | 10.94% |
| 4 | 56 | 21.88% |
| 5 | 70 | 27.34% |
| 6 | 56 | 21.88% |
| 7 | 28 | 10.94% |
| 8 | 8 | 3.13% |
| 9 | 1 | 0.39% |
Multipliers depend on the risk level and the version; see our rows and risk levels guide.
Frequently Asked Questions
What are the odds of hitting the edge slot at 16 rows?
The odds are 1 in 65,536 for each edge slot. A 16-row board has 65,536 equally likely paths, and only one of them goes the same way at every row to reach each edge. That is why the biggest multipliers are so rare.
Can the calculator predict my next drop?
No, it shows probabilities only. Each drop is random and independent of the ones before it, so the calculator can tell you how often a slot is hit over many drops, but it cannot say where the next ball will land.
