3,600 cells. A buy of 0.005 ETH or more destroys one cell per 0.004 ETH, chosen by your transaction hash, never by you. At 1,800 gone — exactly half — it stops and whatever survived is kept forever.
Live stateEvery holeStatusThe picture is 3,600 cells drawn from one seed. Anybody can redraw the identical starting image and check it against whatever is left.
A buy of 0.005 ETH or more destroys one cell per 0.004 ETH — at least one, never more than forty. Which cells is not yours to choose. They fall out of your transaction hash, sha256(tx + counter) % 3600, skipping anything already gone. Nobody can aim.
Nothing is ever repaired. At 1,800 gone, exactly half, it stops — and what is still standing is standing for good.
Remnant pays nothing. It only keeps what you could not take.
