Plinko drops a ball through rows of pegs into a multiplier bucket at the bottom. Rows and risk level are yours to choose. The ball's path is a chain of left/right bounces, so the bucket odds follow the binomial distribution and every setting can be priced exactly.
Multiplier tables
Buckets are listed left to right; the middle bucket is the most likely.
| Rows | LOW | MEDIUM | HIGH |
|---|---|---|---|
| 8 | 5.6 · 2.1 · 1.1 · 1 · 0.5 · 1 · 1.1 · 2.1 · 5.6 | 13 · 3 · 1.3 · 0.7 · 0.4 · 0.7 · 1.3 · 3 · 13 | 29 · 4 · 1.5 · 0.3 · 0.2 · 0.3 · 1.5 · 4 · 29 |
| 12 | 10 · 3 · 1.6 · 1.4 · 1.1 · 1 · 0.5 · 1 · 1.1 · 1.4 · 1.6 · 3 · 10 | 33 · 11 · 4 · 2 · 1.1 · 0.6 · 0.3 · 0.6 · 1.1 · 2 · 4 · 11 · 33 | 170 · 24 · 8.1 · 2 · 0.7 · 0.2 · 0.2 · 0.2 · 0.7 · 2 · 8.1 · 24 · 170 |
| 16 | 16 · 9 · 2 · 1.4 · 1.4 · 1.2 · 1.1 · 1 · 0.5 · 1 · 1.1 · 1.2 · 1.4 · 1.4 · 2 · 9 · 16 | 110 · 41 · 10 · 5 · 3 · 1.5 · 1 · 0.5 · 0.3 · 0.5 · 1 · 1.5 · 3 · 5 · 10 · 41 · 110 | 1000 · 130 · 26 · 9 · 4 · 2 · 0.2 · 0.2 · 0.2 · 0.2 · 0.2 · 2 · 4 · 9 · 26 · 130 · 1000 |
Bucket odds
With n rows there are n+1 buckets and the chance of bucket k is C(n, k) ÷ 2ⁿ. The outer buckets are the rare ones:
- 8 rows: edge bucket 1 in 256, middle bucket 27.3%.
- 12 rows: edge bucket 1 in 4,096, middle bucket 22.6%.
- 16 rows: edge bucket 1 in 65,536, middle bucket 19.6%.
The 1000× bucket on 16 rows HIGH sits at either end, so the chance per drop is 2 ÷ 65,536, which is 1 in 32,768 (0.00305%). The 130× buckets next to it are 32 ÷ 65,536, 1 in 2,048. Most drops on 16 rows HIGH land in the 0.2× band in the middle, which is why the setting feels brutal between hits.
RTP by setting
Multiply each bucket's multiplier by its probability and sum:
| Rows | LOW | MEDIUM | HIGH |
|---|---|---|---|
| 8 | 98.98% | 98.91% | 99.06% |
| 12 | 98.98% | 98.99% | 99.12% |
| 16 | 99.00% | 98.99% | 98.98% |
All nine settings return about 99%. Risk level and row count change the shape of the results, not the long-run return.
Picking a setting
- LOW is a slow grind: most drops return between 0.5× and 1.6×. Good for autobet sessions with a stop-loss.
- MEDIUM adds a real chance of 10× to 41× hits at the cost of more 0.3× to 0.6× drops.
- HIGH is a lottery: a 16-row session of 1,000 drops has about a 3% chance of seeing the 1000× bucket once. Stake accordingly.
Autobet through the concierge supports fixed patterns and limits; for HIGH, set the stop-loss first.
Limits and verification
Bet limits and the maximum profit cap are per coin and shown after login. Zero-amount drops are allowed. Every drop's path comes from the server seed, your client seed and the nonce, with the hash shown inline, so a drop can be recomputed bounce by bounce.
