Zero Zones

Negatives · 30 levels

Pair hot and cold numbers into zones that add to zero.

How to play

1. Drag across touching tiles to fence them into a zone. Tap a zone to undo it, or drag out of it to grow it.
2. Every zone must add up to exactly 0: hot (red) numbers cancel cold (blue) ones, so 3 + 2 + −5 = 0.
3. Put every tile in a zone, keeping to the zone size shown (and the zone count, when there is one).

Look for lonely tiles in corners first: they only have a couple of neighbours to cancel with.
