The crash game, played on grass

Pass the ball, watch the multiplier climb, and bank before the tackle. One shared live match, a provably-fair outcome every round, and a seamless wallet built for casino integration.

Demo mode uses play-money — no account, no sign-up. Just click and play.

A real match, live

Every player joins the same round and sees the same passes, the same tackle, the same crash — driven by one authoritative server.

🔒

Provably fair

Each round's outcome is committed before betting opens and revealed after, linked in a hash chain anyone can verify independently.

💸

Seamless wallet

Casinos hold the money; we never do. Every bet and win is a signed, idempotent callback to the operator's wallet API.

🛡️

Built to certify

Configurable RTP, responsible-gambling controls, a double-entry ledger and an immutable audit trail — ready for the lab.

How a round works

1

Place your bet

During the betting window, stake on one or both slots. Set an auto-cash multiplier if you like.

2

The ball moves

Your team passes forward and the multiplier climbs with every pass. The longer it survives, the higher it goes.

3

Bank before the tackle

Cash out any time to lock in stake × current multiplier. Wait too long and a tackle ends the run — the bet is lost.

4

Or chase the goal

Survive all the way and the team scores — the round pays the capped jackpot multiplier.

For operators

PassKeeper integrates like any modern crash provider: a signed game-launch URL and a seamless wallet API (balance / bet / win / rollback) with idempotent transactions and reconciliation. You keep the player and the funds; we provide the game, the fairness, and a provider-side audit ledger.
