Addition Elimination

iPhone / Style de vie

Each challenge system will randomly generate a target number, and at the same time, a set of numbers will be generated in the middle. You need to select numbers pairwise in the set of numbers, so that the sum of the selected numbers is equal to the target number. When the sum of the two selected numbers equals the target number, these two numbers will disappear. When all the numbers in the number set are eliminated, the challenge is successful.
