Sums Stacker iPhone/iPod Touch
Sums Stacker is a "Math Doodles" activity that provides plenty of addition and subtraction practice, within a recreational math setting. The mathematical puzzle allows users to play with different representations of numbers, while developing their number sense to create strategies to help them solve problems.
The Challenge Blocks with values are piled into three stacks. Each stack is randomly assigned a target sum. Drag values from stack to stack until the sums of each stack equal the target sums.
Solve Mode Strategically solve five random sets in the fewest number of moves. Receive a smiley face for each puzzle solved.
Race Mode Rack up as many points as you can solving puzzles, before time runs out. The timer is represented by a tab of paper that works its way around the edge of the screen.
Easy Mode All three target sums are shown.
Hard Mode To make things a little bit harder, one of the target sums is left as an unknown.
