Plinko calculator
Pick the number of rows and see the exact chance of every slot. Lock a title with a captured paytable to add its multipliers and the RTP they produce.
Optional. Pick a casino and a title, and the calculator uses the RTP in our data for it. Only titles with an RTP figure are listed.
Multipliers belong to each title. Lock a title above to see its table where we have one.

How plinko chances are counted
The ball meets one peg on each row and goes left or right with equal chance. A slot is reached by every path with the right number of right turns, so the chance of a slot is the number of such paths divided by all paths. The multipliers are chosen by the game maker and do not follow from a formula.
Worked example
With 8 rows there are 9 slots and 256 paths. The middle slot is reached by 70 of them, a chance of 27.34%. Each outer slot is reached by one path, a chance of 0.39%.
The far slots hold the top prize, and how rare the top plinko prize is can be worked out separately. To see which plinko title keeps the least, open the edge comparison by game type. Another game where a table of multipliers decides the return is covered by the keno calculator.
What this plinko page cannot show
- It has multipliers only for titles whose table we read from the game. For other titles it shows the chances and says that the table is missing.
- It cannot tell where the next ball lands. Each drop is independent.
- A table can change when a provider updates a game. The date of capture is shown next to the table.
Questions about plinko odds
How rare is the top slot on 16 rows?
One outer slot or the other is hit about 1 in 32,768 drops. In the Plinko XY table we captured, that slot pays 1,000x at high risk.
Does the risk level change where the ball lands?
No. The chances depend only on the number of rows. Risk changes the multipliers: high risk pays more at the edges and less in the middle.
Why is the RTP from the table different from the lobby figure?
For Plinko XY with 8 rows at low risk the table gives 97.03%, while the lobby lists 99.0%. The multipliers on screen are rounded, and the lobby figure may describe a different setting. We show both numbers and do not guess.
Do more rows give a better return?
Not by themselves. More rows spread the ball over more slots and make the outer slots rarer. The return depends on the multipliers the game attaches to those slots.
