By connecting as many same numbered dots as you can. The longer the line, the more points you get and the longer you'll survive.

How to play:
• Connect same numbers on a horizontal or vertical line, cross line.
• Connect-3 or more same numbers to merge them.
• The result of connected value being a multiple of 2: 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048...
• This "2 To 2 - Match 3" will end when you can't connect any more.
