Check any Rainbet Plinko drop against its seed pair and confirm the bucket and multiplier the ball was always going to hit. A free, provably fair Plinko verifier and multiplier checker that replays the path from your server seed, client seed and nonce.
Runs entirely in your browser - your seeds never leave this device.
Provably fair verification lets anyone independently recompute a game's result from its server seed, client seed and nonce - confirming the casino could not have altered the outcome after the bet. Browse all casinos & games
A Rainbet Plinko ball bounces through a triangle of pins - 8 to 16 rows depending on your setting. At each row it goes left or right, and that decision is not random in real time: the casino generates one HMAC-SHA256 float per row from your server seed, client seed and nonce. A float at or above 0.5 sends the ball right; below 0.5 sends it left.
Add up the right-moves and you get the landing bucket, which maps to a multiplier from the low, medium or high risk table for that row count. Because every row's float is fixed by the seed pair, the drop is fully reproducible from the same three inputs.
Edge buckets pay the big multipliers - up to 1,000x on 16-row high risk - but are the least likely landing spots, because reaching them needs almost every bounce to go the same way. The center pays under 1x and is where most balls land, following a binomial distribution. Higher risk widens the extremes while thinning the center. Across settings the Plinko house edge is about 1%, giving an RTP near 99%.
| Landing bucket | Multiplier |
| Far edge | 1,000x |
| Near edge | ~130x |
| Mid-outer | ~26x |
| Inner | ~0.2x |
| Center | 0.2x (most common) |
| House edge | ~1% |
Plinko's landing spot is a sum of independent 50/50 bounces, so the center is overwhelmingly the most likely outcome and the jackpot edges are rare by mathematical necessity - no release timing or pattern changes that. Lower risk and fewer rows tighten results around small, frequent multipliers; high risk with 16 rows dangles the 1,000x edges but lands there a fraction of a percent of the time.
If you play, pick a risk and row count that match your tolerance, set a budget, and remember that the most common result on high risk is a sub-1x bucket. The verifier's value is confirming a past drop was fair - it cannot influence or predict where the next ball lands.
No. Each row's left/right float comes from the hidden server seed, so the bucket is unknowable until the seed is revealed. This tool verifies past drops; it cannot predict the next one.
Lower risk and fewer rows keep results near the center with small, frequent multipliers; high risk with 16 rows offers the 1,000x edges but lands there very rarely. The house edge is about 1% across settings.
Rotate your seeds to reveal the server seed, then paste it with your client seed and the bet's nonce above. The tool replays the per-row path and shows the bucket - matching it proves the drop was fair.
The bucket is the sum of independent left/right bounces, which follows a binomial distribution peaking at the center. Edge buckets need a near-unbroken run one way, so they are rare.
More rows add more buckets and bigger edge multipliers, but also make the edges harder to reach. It raises variance rather than expected value.
No. Every row's direction is fixed by the seed pair and nonce before release; the animation just plays out a predetermined path.
The house edge is about 1% across risk levels, so the Plinko RTP is roughly 99%. Risk and row count change the variance and the multiplier table, not the underlying edge.
