Chromoblox comes from Dan Bravender. This game is very similar to the card game SET. The object is to clear the board by selecting 3 tiles that are all different or are all the same.

Important: the selected pieces can only come from the bottom of the columns.

Look at the first image. Legal move: the green heart from bottom of column 1, then the blue triangle from column 1, then the red circle from column 5.
I don't know how many levels there are.  I'm guessing I've done about 25.https://apps.apple.com/us/app/chromoblox/id1480608922
