Quick answer: Plinko is a casino game where you drop a ball through rows of pins and it lands in a slot at the bottom that pays a multiplier. Middle slots are most likely and pay little; edge slots are rare and pay big. You choose the number of rows and a risk level before each drop. Popular versions like Spribe’s Plinko have a 97% RTP and are provably fair, so no strategy or app can steer the ball.

How to play Plinko
- Set your stake.
- Choose the number of rows. More rows spread the results wider and raise the edge multipliers.
- Pick a risk level. Higher risk lowers the middle payouts and raises the edge payouts.
- Drop the ball and watch where it lands. The slot’s multiplier is your payout.
- Use auto play to drop many balls with stop-loss and stop-profit limits.
Plinko odds explained
At each pin, the ball goes left or right with equal chance. That makes the landing spot follow a bell curve: most balls end up near the middle, and very few reach the edges.
| Rows | Chance of landing in the centre slot | Chance of reaching an edge slot |
|---|---|---|
| 12 rows | About 22.6% | About 0.05% (either edge) |
| 16 rows | About 19.6% | About 0.003% (either edge) |
On 16 rows, an edge slot is hit roughly once in every 33,000 drops. That’s why the biggest Plinko multipliers are so rare. In the main versions, the RTP stays the same or very close to it whatever rows or risk you pick.
How likely is each Plinko slot to be hit?
A ball that falls through n rows of pins makes n left-or-right bounces. To land in slot k, counting from the left edge and starting at 0, it must bounce right exactly k times. C(n, k) of the 2n possible paths do that, so:
P(k) = C(n, k) ÷ 2n
Worked example on 12 rows: there are 212 = 4,096 paths. The centre slot (k = 6) has C(12, 6) = 924 of them, so its chance is 924 ÷ 4,096 = 22.6%. Each edge slot has only 1 path, so its chance is 1 ÷ 4,096 = 0.024%.
| Slot, counted from the edge | 8 rows | 12 rows | 16 rows |
|---|---|---|---|
| Edge (k = 0) | 0.39% | 0.024% | 0.0015% |
| k = 1 | 3.13% | 0.29% | 0.024% |
| k = 2 | 10.94% | 1.61% | 0.18% |
| k = 3 | 21.88% | 5.37% | 0.85% |
| k = 4 | 27.34% (centre) | 12.08% | 2.78% |
| k = 5 | 19.34% | 6.67% | |
| k = 6 | 22.56% (centre) | 12.22% | |
| k = 7 | 17.46% | ||
| k = 8 | 19.64% (centre) |
The other half of the board mirrors these numbers. Taking both edges together, a ball reaches an outer slot about once in 128 drops on 8 rows, once in 2,048 drops on 12 rows and once in 32,768 drops on 16 rows. That is why the top multipliers, which sit in those outer slots, are so rare.
The RTP sets the long-run cost. 1,000 drops at €1 cost about €30 on average at 97% (Spribe) and about €10 at 99% (BGaming). Rows and risk change how bumpy the ride is, not that average.
Does any Plinko strategy help?
- Low risk gives steadier, smaller results; high risk loses more often but can hit a big multiplier. Neither beats the house edge.
- Set a budget and stop limits, especially with auto play, which can burn through money quickly.
- Try the demo to see how each risk level behaves.
- Ignore “Plinko strategies” and apps: every drop is random and set by cryptographic seeds.
Is Plinko rigged?
Licensed Plinko games are provably fair. Each drop’s path comes from a server seed, your client seed and a counter, which you can verify after the round. The casino’s edge comes from the payout table, not from moving the ball. Learn more in our provably fair games guide. Be wary of Plinko apps that promise easy real-money withdrawals. Only play at licensed casinos.
