The goal of each puzzle is to make every big circle on the board the same color as the target color. You have a limited amount of red, yellow, and blue in the three small circles above the target color bar that you can mix into the big circles to change their colors. Once every circle on the board is the target color, you move on to the next puzzle.
Tealday generates endless variation through 12 levels of difficulty. There are 10 target colors in each level. Every time you play a puzzle it is totally new.
The first level of Tealday is free, and you can replay it as much as you want. You can unlock the other 11 levels for an in-app purchase of $1.99.
