One room. One block.
Bitcoin creates a new block roughly every ten minutes. NextBlock opens a live room for the one that has not arrived yet.
Make the call
Choose when you think the next block will land. Your call locks for that round.
Wait together
Talk with everyone watching the same live event. Links are blocked to reduce scams.
Seal the room
When the block arrives, scoring runs and the room moves into the archive.
Start again
The next room opens immediately. No money, custody, trading, or wagering is involved.
