The Arcade · One tap

Timechain

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?

Timechain

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.

The real chain is at block 958,216 · yours starts at zero

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.
