It's so simple... get to the target number using the supplied set of numbers on the right in combination with the mathematical operators on the left. The only requirement is that you must use all of the numbers in your answer.
There are five different levels, the first four of which it is guaranteed that you can reach the target number... the fifth level... well, it is for you to work out if it is possible! Number splits provide an extra twist to the game!
A special times table feature helps you practice your mental arithmetic from the 2 times table up to the 12 times table, with achievements unlocked if you beat a target time.
Leaderboards help you measure your progress and compete with others in your social circles or with everyone else playing around the world - discover how you rank globally!
The initial installed app is a trial version with the only difference to the full version being that for some levels (medium, hard and solvable, and certain times tables) you are limited to the number of games you can play before a timeout period. A simple, one time in app purchase removes this limitation forever.
