How it works

Every drop sends one ball down a triangle of pegs. At each row it bounces left or right, and the bucket it lands in sets your multiplier. Edge buckets are rare and pay the most; the middle is where most balls land. More rows and higher risk spread the payouts further apart.

Try the demo right away with 1,000 local chips, or sign in with your wallet (a text signature, never a transaction).

Claim your daily chips. Holders of the project's coin get more chips, a bonus on wins and the holders' table.

Choose a stake, a risk level and 8 to 16 rows, then drop. Every bounce can be re-checked below.

Bucket multipliers

Multiples of your stake, left edge to right edge (the board is symmetric). Payout = floor(stake × multiplier) in whole chips. Holders get their tier's win bonus on top of the profit of a winning drop.

Fairness mapping and RTP

Each drop uses one nonce of your seed pair. The bytes are HMAC_SHA256(serverSeed, clientSeed:nonce) (then :1, :2 … if more are needed), read 4 bytes per float: b0/2^8 + b1/2^16 + b2/2^24 + b3/2^32.
A board with n rows uses floats 0 … n−1, one per row. Float i < 0.5 sends the ball left at row i; ≥ 0.5 sends it right.
The bucket is the number of right bounces, 0 … n from the left edge. Its multiplier comes from the table above for your rows and risk, and the payout is floor(stake × multiplier). The same code runs on the server and in the verifier on this page.

So the chance of bucket k is exactly C(n, k) / 2^n, and the RTP of a board is Σ C(n, k) · multiplier_k / 2^n. Every value below is computed from the live table on this page, not typed in by hand.

The RTP is before rounding each payout down to whole chips. At stakes that are a multiple of 10 nothing is ever rounded; at other stakes rounding costs less than 1 chip per drop.

Holder perks

Sign in with your wallet to keep chips, claim daily chips and appear on the leaderboard. Holding the project's coin unlocks bigger daily chips, a small bonus on wins and the holders' table.

Daily chips reset at 00:00 UTC. Claiming on consecutive days adds a streak bonus (+10% per day, up to +50%). The holder tier is read from your wallet's token balance on Solana at sign-in and every 10 minutes. Perks are bonus play only: chips have no cash value.

Provably fair

Every result is decided on the server from seeds you can check. Before you play you see the SHA-256 hash of the server seed. Each play uses HMAC-SHA256(serverSeed, clientSeed:nonce), and the game's mapping below turns those bytes into the result. When you rotate, the old server seed is revealed, so you can re-run every past result yourself.
