Mine a block by hand
A block hash decides every draw, and it is only fair because it is so hard to find. Feel it: your browser mines the next block's header, nonce by nonce, the way the first miners did in 2009.
He strikes at 12 zero bits, cheers at 20, rains sats at 24, dances at 32.

Best finds, checked by the server
Every entry was mined on a real tip in someone's browser, then hashed again by the server before it went up.
Reading the board…
How lucky the last 48 blocks were
Each bar is a real block: how many more zero bits its hash had than it needed. The luckiest was block 973,720: 85 zero bits where 78 would do.

Check block 973,755 yourself
Block 973,755's 80-byte header, exactly as its miner broadcast it. The draw is keyed on its hash, so the hash has to be real work.
