Tap to stack the next block on the chain. Every 21 blocks the reward halves and the chain speeds up · how high can you build?
Tap to drop the sliding block on the chain. Clean drops keep their width · overhang gets sliced off. Every 21 blocks the reward halves and the chain speeds up.

Reading the board…
The chain narrows
Each block keeps only what overlaps the one below it · the overhang is sliced away. A perfect drop snaps flush and keeps the full width. Miss entirely and the chain is orphaned.
The halving is the clock
Blocks start paying ₿50. Every 21 blocks the reward halves · 50, 25, 12.5 · and the chain slides faster. Being early pays more. That is not a game mechanic we invented.
Sats are the score
Every block banks its reward, scaled by how cleanly you dropped it. Perfect streaks build a combo up to 3x. Your best posts to the public board under an anonymous arcade handle · no accounts, nothing typed.
