Stack numbered balls. Build descending chains 8-7-6, 5-4-3-2-1 and touch one to start the count down: it detonates from the highest number down to the lowest, branching into every neighbour that continues the sequence.

But every chain you build lights its own fuse. Leave a detonable chain alone for nine seconds and it counts itself down without you.

How to play

1. Stack — Balls drop into six columns. Fill a column to the top and it's game over.
2. Build a Countdown — Put neighbouring balls in descending order: 5-4-3, or 8-7-6-5. Three or more different numbers, touching orthogonally (diagonals don't connect).
3. Count down — Tap any ball in the chain. It detonates from the highest number down to the lowest, branching into every neighbour that continues the sequence. Longer runs pay more. The chain can split in diferent branches, also add more numbers on the fly.

The catch: a chain with 3 or more consecutive numbers has a auto-detonate countdown. After about 7 seconds it blows on its own terms, not yours. The board never pauses while a countdown is running, so collapsing stacks chain into fresh runs and cascade.
