Instructions:

Place batteries such that each row and column gets the correct total of green and red tiles. Not every tile will be filled!

Green tiles must not touch green tiles, and red tiles must not touch red tiles. Diagonal touching is fine.

If you want to mark a battery as definitely empty, press and hold it.
