Bet × drops × edge
The expected cost of any Plinko session is three numbers multiplied together: your bet, the number of drops and the house edge. At $1 a drop, 20 drops a minute and a 1% edge, an hour costs $12 on average. Auto-play at maximum speed can exceed 60 drops a minute, which triples the figure. Nothing about rows or risk changes this – they only change the swing around it.
The swing
The one-sigma band is the range in which about 68% of sessions finish. On low risk it is tight: an hour at $1 might finish anywhere from −$40 to +$16. On 16 rows high risk the same hour has a one-sigma band of roughly ±$190, and the distribution is skewed – most sessions finish well below the mean and a few finish far above it. If the lower bound of the band is more than you are willing to lose, lower the bet or the risk.
Rakeback changes the net
Enter your rakeback rate and the calculator shows how much of the expected cost comes back. At 20% it turns a $12 hour into a $9.60 hour. See our rakeback calculator for the full comparison across brands.
