Addions is a numbers puzzle where numbers move freely around.
In Addions you create groups of one, two or three numbers and match other groups with similar value to create a greater number.
Join equal values to create a bigger number.
(1)=(1) => (2)
Join different values to create a group, then match the group with another group of equal value.
(2+3) = 5
(2+3)=(5) => (10)
You can also do a partial match (if the value of one of the groups is contained within the other group)
(20+8+2) = 30 and (9+1) = 10
(8+2) = (9+1) => 10 = 10 => (20)
20 = 20 => 40
The free-moving numbers puzzle!
