Kitty Kat Pop

There are many kitty cats to be rescued in this game. They are up for adoption and they need a home. Your job is to try and rescue as many as you can.
They are inside colored boxes and they need to be rescue at least three at a time. You will need to match boxes of the same color and tap on one of them to rescue the kitties. The bigger the chain of saree color boxes you pick, the more points you will get. Try to rescue as many as you can in one tap.
The goal of the game is to leave as few boxes as possible at the end. Preferably leave no boxes at all so all kitties can be rescued.
