About this game
The developer's description, from the game's Steam store page.
Blackout is an indie puzzle game inspired by old-school handheld games from the 80s and 90s.
The game offers 50 levels ranging in difficulty from 1 to 50.
This puzzle is solvedby using a 5x5 grid as a map and your objective is to turn off the whole grid using a 3x3 cross/plus sign.
In the menu you will also find a practice menu to play to train and keep your cognitive health and to keep the game competitive even after completing it.
Achievements will be completed through finishing levels, with a secret whiteout achievement to be completed.
