Plinko with USDT
Plinko is a game where a ball bounces off pegs row by row and lands in one of the buckets at the bottom. Each bucket multiplies your stake: the outer ones are rare and pay the most, the middle ones are common and pay less. You choose the risk and the number of rows; every board returns 95.5% to the player.
How to play Plinko
- Enter your stake, from 0.10 USDT.
- Choose the risk (low, medium or high) and the number of rows: 8, 12 or 16.
- Press Drop ball. The multiplier of the bucket it lands in is applied to your stake.
Plinko boards: risk, rows and payouts
Every board returns the same on average; only the spread changes. Low risk pays small amounts often; on high risk most drops pay 0.2x, but the outer buckets pay up to 1000x.

Where the odds come from
At every row the ball bounces left or right with equal odds. The bucket is the number of bounces to the right, so on an n-row board the ball lands in bucket k with probability C(n, k) / 2n. On 16 rows each outer bucket catches one ball in 65,536: high risk’s 1000x comes up with a probability of 0.0031%.
How to verify a drop
The ball’s path is fixed by the seeds: for row i it takes byte 4 + i of HMAC-SHA256, keyed with the secret seed, of “your seed:round number”; an even byte bounces left, an odd one right. How to check it yourself is on the provably fair page.
Frequently asked questions
What is the RTP of Plinko?
95.5% on each of the 9 boards: the multiplier tables are set so the average payout is the same at every risk and row count.
Which board should I pick?
Low risk gives frequent small payouts, topping out at 5.5x to 16x. High risk pays 0.2x more often, but its outer buckets pay up to 1000x. The average payout is the same, so pick the spread you like.
Can I predict where the ball lands?
No. The path is computed from the secret seed, which is only revealed after its rounds, and from your seed. It can’t be predicted before the drop, but it can be checked afterwards.
