Three of 3's

You have to join three buttons with the same value, to get higher valued buttons. Triple them up and get an even higher valued button. The ultimate goal is to get a 6561 gold button, and for the hardcore gamer there is the nearly impossible mission: a 19683 black button.
To get there you need to make a lot of smart decisions to avoid unnecessary clutter. Think strategically and maneuver. You can challenge friends and they can challenge you.
This game is inspired by the classical 2048 game, but it is more complicated and you have more choices in every single step. Relaxing and challenging.
