About Fluxgrid
Fluxgrid is a logic puzzle on a square grid of charged cells. Tapping a cell pulses it: its own charge and the charge of its neighbours each go up by one, wrapping back to zero at the top. Clear the board by bringing every cell back to zero.
How to play
Plus cells pulse themselves and the four cells beside them. Cross cells, the round ones with a dashed ring, pulse their four diagonals instead. On Easy levels a cell is simply on or off; from Medium upwards a cell can hold two or three levels of charge, so you count rather than just toggle. At Expert the edges of the grid wrap around.
Tips
- The order of your taps never matters — only how many times each cell is tapped. Plan, then tap.
- Tapping a cell as many times as there are charge levels undoes it completely, so you can never get stuck.
- Cross cells are the key to corners and to any cell nothing else seems to reach.
- Par is the length of the reference solution. Beating it is rare and worth extra points.
