21 is an addictive puzzle game, just add up and achieve the goal.
How it works:
Adding up the numbers, you must meet or exceed the number on the smallest box. This is your goal.
The units can be add up between them. 2 + 5 = 7, but can not be add up to the tens. 2 + 17 = Null
Hundreds can be add up between them. 101 + 120 = 221
The Star (wildcard) can be add up to any number.
The tens can only be add up between them, if start with the same number. 12 + 13 = 25 but 12 + 23 = Null
For new game, press box points (upper box).
