🎲 A 1% Drop Rate

63% after 100 tries, a median wait of 69, and why pity timers exist. Counting only: nothing spins or opens.

From our friends at Fold Commons

The same wait, in a cell. In OneLetterLottery, three of the 64 codons stop a gene, so a random string meets a stop about once every 21 calls: a 3-in-64 drop rate, and the same arithmetic as this page.
