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
stubborn genius 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.
Keep it clean and try to keep equal buttons together and join them as soon as possible.
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.
