Play

Six games, playable right here.

Each is a complete template: play it, then open it in the studio and change everything.

All games
$SANDBOX

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. 1. Every $SANDBOX trade pays a feeThe creator share goes into the contract vault, not into a pocket.
  2. 2. The vault fills upNobody can drain it: the owner has no withdraw function.
  3. 3. Every 24 hours, it splitsThe most played maps of the last 24 hours share the vault, pro rata.
  4. 4. With no room for farmingA wallet is required to play, and a wallet counts at most ten plays per map.

One set, five moods

Click. A preset combines sky, lights, fog and post-processing.
