GlowGrid is a relaxing and addictive puzzle game.
The gameplay is very easy to understand, but the challenge will definitely increase as you go on. Every level is filled with different shapes that need to be removed to make space for new ones. It's a good idea to remove the same color tiles as they will start disappearing, leaving you with less space to play.
There are tons of different shapes to remove and new ones to discover as you play. It's a good idea to remove the big tiles first as they will take up the most space on the screen.
You will need to think carefully about how to fill up the power bar. It's a good idea to remove the tiles one by one, starting from the top left corner of the screen.
