Play to set a score, then submit it to the board.
How to play
- Every tile shows a number that is both its point value AND its fuse.
- Each tick, every tile’s number drops by one.
- Tap a tile to harvest it for its current value before it reaches zero and cracks.
- Three cracks end the run. A fresh tile drops in to replace each one you harvest.
Strategy & tips
- Triage constantly: a 9 is worth more but lives longer, while a 2 is about to detonate.
- Harvest strictly-descending values in quick succession to build a combo multiplier up to x8.
- Do not hoard high tiles too long — the whole board ticks down together.
- Sweep up low, short-fuse tiles before they crack, even for a few points.
- Balance greed (chasing combos) against survival (avoiding cracks) every second.
FAQ
What is the twist in Zero Hour?
A tile’s number is both its score and its countdown — value and time are the same thing, so you constantly trade worth against survival.
How does a run end?
When three tiles crack (reach zero before you harvest them), the game is over.
