Plinko odds
In Plinko each ball has a 50/50 bounce at every peg, so most balls land in the middle slots and the edges are very rare: on 16 rows, the two outer slots together hit about 1 in 32,768 drops. The RTP, about 97% to 99%, is the same whatever risk level you pick; risk only changes how spread out the wins are.

Plinko looks like pure chance, and it is, but it’s chance with a very particular shape. The ball almost always lands near the middle, the big multipliers on the edges are extraordinarily rare, and the settings you choose decide how bumpy your session will be. This guide shows the real odds, row by row, and what they mean in Rands.
How Plinko works
You choose a stake, a number of rows (often 8 to 16) and a risk level (low, medium or high). A ball drops from the top of a triangle of pegs. At each row it bounces left or right with equal probability, and it lands in one of the slots along the bottom, each with a multiplier. Your stake is multiplied by that slot’s value.
The multipliers are lowest in the middle, often below 1x, and highest at the edges.
Why the middle wins almost every time
To land on the far left edge of a 16-row board, the ball has to bounce left at all 16 pegs. The chance of that is ½ multiplied by itself 16 times: 1 in 65,536. To land in the centre, it needs eight lefts and eight rights in any order, and there are 12,870 different ways to do that.
That’s the whole game in one sentence: there are many paths to the middle and only one path to each edge.
The odds on 16 rows
| Slot (from the edge) | Chance per drop | Roughly 1 in |
|---|---|---|
| Edge (each side) | 0.0015% | 65,536 |
| 2nd | 0.024% | 4,096 |
| 3rd | 0.18% | 546 |
| 4th | 0.85% | 117 |
| 5th | 2.8% | 36 |
| 6th | 6.7% | 15 |
| 7th | 12.2% | 8 |
| 8th | 17.5% | 6 |
| Centre | 19.6% | 5 |
Both edges together: about 1 in 32,768 drops.
Fewer rows, less extreme
On 8 rows there are only 256 possible paths. Each edge slot hits 1 in 256, so both edges together hit about 1 in 128, and the centre slot catches about 27% of balls. Edge multipliers on 8 rows are therefore much smaller.
What the risk level does
The risk level changes the multipliers, not the bounces. The ball falls the same way at any risk level.
- Low risk: middle slots pay close to 1x (say 0.5x to 1.1x), edges pay modestly. You lose slowly and steadily.
- High risk: middle slots pay very little (often 0.2x), edges pay hundreds or even 1,000x. Most drops lose most of their stake.
Take an illustrative 16-row, high-risk board in the style of common crypto Plinko games, where the five centre slots pay 0.2x and each edge pays 1,000x. Roughly 79% of drops land in those centre slots, meaning you lose 80% of the stake on four drops out of five. The two 1,000x edges together account for only about 3% of the game’s total return, because they come up so rarely.
That’s worth sitting with. The 1,000x slot is the reason people play high-risk Plinko, and it contributes almost nothing to what you get back on an ordinary day.
RTP stays the same
In most Plinko games the multipliers are tuned so that the RTP is roughly equal at every row count and risk level. From our games data:
An RTP of 97% means a 3% house edge: on average you lose R3 of every R100 you drop, whichever settings you choose. Changing rows and risk changes the spread, not the cost.
A worked example in Rands
Say you have R1,000 and drop balls at R10 each, 100 drops, on a game with a 97% RTP. That’s R1,000 in total bets and an expected loss of R30.
Low risk, 8 rows. Most drops return R5 to R11. You’ll rarely lose fast. A typical session ends somewhere around R850 to R1,050. You almost never see a big win.
High risk, 16 rows. About 79 of your 100 drops return R2. That’s R158 back from R790. To break even you need a handful of mid-board hits (9x, 26x) or a rare big one. Many sessions end at R300 to R600; a few end well ahead. The chance of seeing a 1,000x edge in 100 drops is about 0.3%.
Same expected cost, completely different session. If you want your R1,000 to last, choose low risk. If you play high risk, expect long runs of losing drops and size your stake for them.
Plinko “strategies” that don’t work
- Switching risk levels after a loss. Each drop is independent. The board doesn’t owe you an edge hit.
- Auto-drop at speed. Faster drops don’t change the odds; they just get you to the expected loss sooner. At one drop a second, R10 drops mean R36,000 of bets an hour.
- Martingale on Plinko. Doubling stakes after a loss runs into your budget or the max bet quickly, especially on high risk.
- Watching for “hot” slots. Results are random every time.
The only real choices are your stake, the number of drops and which game you play (higher RTP is cheaper).
Provably fair Plinko
Many Plinko games are provably fair: before you play you get a hashed server seed, and you supply a client seed. After each drop you can check that the path was produced by those seeds and wasn’t altered. Our provably fair verifier explains how to check a result.
Provably fair proves the result wasn’t tampered with. It doesn’t change the multipliers, which is where the house edge lives.

Plinko and bonuses
Plinko and other instant games often count less towards wagering, or are excluded. Because the house edge is low, some casinos ban them from bonus play entirely. Check the game weighting in the bonus terms before you use bonus money on Plinko.
The bottom line
Plinko’s odds are completely transparent: a bell curve with a fixed house edge of a few percent. Low risk makes your balance last; high risk gives you a tiny chance of a big win in exchange for losing most drops. Neither turns Plinko into a way to make money. Set a budget, choose a stake that gives you enough drops, avoid auto-drop marathons, and stop when the budget is spent. Free help is available on 0800 006 008.

Frequently asked questions
What are the odds in Plinko?
Every peg sends the ball left or right with equal chance, so landing slots follow a bell curve. On 16 rows, the centre slot catches about 19.6% of balls, while each outer slot catches 1 in 65,536.
Can you win real money on Plinko in South Africa?
Yes, at casinos that offer Plinko games for real money, but the game has a built-in house edge of about 1% to 3%. Over many drops you'll get back less than you put in.
What is the best Plinko strategy?
There's no strategy that beats the RTP. You can choose how the risk feels: low risk and fewer rows give steady small results; high risk and 16 rows give long losing runs with rare big hits. Pick a stake that suits your budget.
Is Plinko rigged?
Provably fair Plinko versions let you verify every drop using the published seeds and hash. That proves the result wasn't changed after your bet, but it doesn't remove the house edge built into the multipliers.
Does the number of rows change the RTP in Plinko?
In most Plinko games, no. The multipliers are set for each row count and risk level so the RTP stays roughly the same. More rows push the extremes further out and make them rarer.
