Plinko, Dice and Limbo: tables, odds and RTP
Plinko, Dice and Limbo are single-round instant games, all with a 97% base RTP: in Plinko a ball drops into a slot with a fixed multiplier; in Dice you choose the chance and the payout is 97 ÷ chance; in Limbo you choose the target and the chance of reaching it is 97% ÷ target.

Plinko
The ball crosses 8 to 16 rows of pins; at each pin it goes left or right with a 50% chance. That is why the centre slots are the most likely and the edges the rarest (with 16 rows, each edge comes up once in 65,536). The chosen risk changes the shape of the table, not the RTP.
| Rows | Low risk | Medium risk | High risk | Chance of each edge |
|---|---|---|---|---|
| 8 | ×4.1 | ×8.3 | ×17 | 0.3906% |
| 10 | ×5.7 | ×13 | ×33 | 0.0977% |
| 12 | ×7.7 | ×20 | ×60 | 0.0244% |
| 14 | ×9.9 | ×30 | ×110 | 0.0061% |
| 16 | ×13 | ×46 | ×195 | 0.0015% |
All 15 combinations of rows and risk were simulated with 10 million balls each; all fell inside the 99.9% interval around 97%.
Dice (over or under)
The round’s result is a number from 0.00 to 99.99. You pick over or under a value and, with it, your chance. Payout = 100 × RTP ÷ chance%.
| Chance | Payout | RTP |
|---|---|---|
| 1% | ×97 | 97% |
| 5% | ×19.4 | 97% |
| 10% | ×9.7 | 97% |
| 25% | ×3.88 | 97% |
| 49.5% | ×1.9596 | 97% |
| 50% | ×1.94 | 97% |
| 75% | ×1.2933 | 97% |
| 95% | ×1.0211 | 97% |
Limbo
You set a target multiplier from ×1.01. The result is RTP ÷ (1 − r); if it is equal to or above the target, you get the target. The chance of reaching target x is 0.97 ÷ x: ×2 comes up 48.5% of the time, ×10 9.7%, ×1,000 0.097%. The maximum target is ×1,000,000. It is the individual, instant version of a crash game.
What about the scratch card?
The Scratch card (Raspadinha) is instant too, but with fixed prizes: 3 matching values among 9 cells pay that value. Each prize has a fixed, published probability, set for a 96% base RTP.
