Decent puzzle game. 50 levels.
Activate and deactivate addition and multiplication fields in columns and rows and areas according to target sums and counts.

I 100%-ted the 50 levels in 3.8 hours.

I can recommend it if you enjoy this type of game.
If you haven't played Hexcells yet, prefer that over this one. It feels better, I assume due to polish with visuals, animation, etc. When you have exhausted Hexcells, this is a decent filler/extension/alternative.
