Both are instant games with simple rules and adjustable risk. They differ in one respect that matters: whether a decision happens during the round.
In a crash game a multiplier rises until it stops at a moment fixed before the round began, and you choose when to take it. The decision sits inside the round. In Plinko every choice is made before the ball is released; once it falls there is nothing to do but watch.
This makes Plinko the simpler of the two to play well, in the narrow sense that there is no in-round decision to get wrong.
| Plinko | Crash games | |
|---|---|---|
| Decision during round | none | when to exit |
| Round length | seconds | seconds to a minute |
| Typical RTP | 97%–99% | 96%–99% |
| Variance control | rows and risk level | chosen exit multiplier |
| Provably fair | commonly | commonly |
Both have a fixed house edge, both fix the outcome before the visible part of the round begins, and in both the published return is delivered over numbers of rounds no player reaches. Neither rewards skill, and no system changes either.
