Six steps, in this order, every time.

Six games, playable right here.
Each is a complete template: play it, then open it in the studio and change everything.
Fees land in a vault. The most played maps take it.
No jury, no curation: the last 24 hours of play decide, and every round is settled on chain.
- 1. Every $SANDBOX trade pays a feeThe creator share goes into the contract vault, not into a pocket.
- 2. The vault fills upNobody can drain it: the owner has no withdraw function.
- 3. Every 24 hours, it splitsThe most played maps of the last 24 hours share the vault, pro rata.
- 4. With no room for farmingA wallet is required to play, and a wallet counts at most ten plays per map.
