the manifest

Every machine holds exactly 500 capsules: 1 gold, 4 silver, 20 bronze, 475 plain. The contract keeps the count, and the page shows it live.

a turn

500 $GACHA: 70% into the pot, 30% burned. Up to 10 at once.

the drop

Your capsule drops one block after your turn, drawn from exactly the capsules still in the machine, using that block's hash. Anyone can drop waiting capsules, and every new turn drops a few.

what's inside

Every capsule is a toy: an NFT drawn on chain, one of twelve kinds. Bronze pays 1.5% of the pot, silver 8%, gold 30%, the moment it drops.

the odds move

Draws are without replacement. Every plain toy that comes out makes the metal ones likelier, and the page shows the odds for the very next turn.

refills

When the last capsule drops, the machine refills with the same 500. Whatever is left in the pot carries into the next machine.

left too long

A turn nobody drops within about 240 blocks still comes out, as the lowest capsule left.

what the contract cannot do

Hold ETH, change the manifest or the price, pay the pot to anyone but a metal capsule, pause, or be upgraded. The owner key names the token once and can do nothing after.

the risk

Unaudited. Most turns are a plain toy and nothing else. The randomness comes from a block hash, which the chain's sequencer could in principle influence.
