At each peg the ball goes left or right with a 50/50 chance, so the slot odds follow a binomial curve. The multipliers are our own, set to return about 99% on average. Play money only.
The Plinko simulator drops a ball through rows of pegs into a row of slots, each with its own multiplier. Every slot’s chance and pay is shown next to the board, along with the overall return. With 12 rows on medium risk, the centre slot catches the ball 22.56% of the time and pays 0.21×, and each edge slot is 1 in 4,096 for 8.8×. It’s free, and the money is play money.
How Plinko works
At every peg the ball goes left or right with a 50/50 chance. With 12 rows, it makes 12 of those choices, and the slot it lands in depends only on how many times it went right. That gives a binomial spread: most balls land near the middle, very few reach the edges.
Exactly 12 rights, or 12 lefts, is (1/2)¹² = 1 in 4,096. With 16 rows the edges drop to 1 in 65,536, which is why the multipliers there are so much bigger.
Plinko risk levels
- Low risk: the middle slots pay close to your stake back and the edges only a few times it. A calm ride.
- Medium: the centre pays well under your stake, the edges up to about 10×.
- High: the centre and its neighbours pay a fraction of the stake, and the edges pay up to 72× on 16 rows. Most balls lose, a few win big.
The multipliers on this board are our own, set so every combination returns about 99%. Real Plinko games publish their own tables and RTP, which vary by site. The maths behind the slot odds is identical everywhere.
Plinko strategy: what you can and can’t change
No. Each drop is independent, and the house edge is built into every slot’s multiplier, so no choice of rows or risk changes the average return much. What you choose is the ride: low risk loses slowly and steadily, high risk loses most drops and occasionally pays a lot. Drop 100 balls at once and compare “Returned” with the table return to see how much a short session can wander.
The “strategies” you’ll see online fall into three groups. Picking more rows or higher risk changes how often you hit the big edge slots, not what you get back on average. Doubling after losses is Martingale, and it fails here for the same reason it fails at roulette: a long run of small multipliers is normal on high risk. And patterns in recent drops mean nothing, because each ball is random and independent.
What does work is choosing a stake you can afford for the number of drops you want, and setting a stop point. Low risk on 16 rows gives the longest session for the money; high risk on 16 rows gives the rare 1,000× and the fastest losses.
