Color Binder is a Color Puzzle that is terribly difficult to win. It is played on a 4x4 grid and starts with 2 purple blocks in the corner. Taping on one and then the other makes a indigo block. two of those makes a magenta block and so forth. the order goes like this:
purple
indigo
magenta
blue
cyan
green
yellow
orange
red
bronze
silver
gold
platinum
tapping a block and then empty spot moves the block. If you do that too much you will lose.

Combine 2 platinum blocks to win and see how high your score can get!
