How to play Fluxgrid
Two minutes to learn, a while to master.
1
Tap any node. It pulses — its own charge and its neighbours' each rise by one.
2
Charge counts up and then rolls over: on a 3-level board, 2 becomes 0 again.
3
Most nodes reach their four edge neighbours. Dashed ✕ nodes reach their four diagonal neighbours instead — they're the interesting ones.
4
Win by returning every node to zero. Tapping the same node enough times undoes it, so nothing is ever a dead end.
