Game Mechanic
Ball-drop arcade game with adjustable risk levels and row counts
Step-by-Step Guide
- 1
Choose your risk level (Low, Medium, or High) which changes the multiplier values at the bottom bins.
- 2
Select the number of rows (8–16) — more rows means more pegs and a wider spread of possible outcomes.
- 3
Set your bet amount and click Drop to release the ball from the top of the board.
- 4
The ball bounces left or right at each peg with equal probability, following a path determined by the provably fair system.
- 5
When the ball lands in a bin at the bottom, your bet is multiplied by that bin's value and added to your balance.
Provably Fair System
Each peg bounce is determined by a single bit derived from HMAC-SHA256(server_seed, client_seed:nonce:cursor). For a 16-row game, 16 random bits are extracted from the hash output. Bit = 0 means bounce left, bit = 1 means bounce right. The server seed hash is shown before you drop — after rotating seeds, you can recompute every bounce independently.
Visit the Fairness Verification page to verify any past round with your seeds.
