iStack is the official Speed Stacks sport stacking game for iPhone and iPod Touch. Approved by the World Sport Stacking Association (WSSA), iStack lets you stack anywhere.

Test your finger stacking skills with one of the three WSSA competition stacks; the 3-3-3, 3-6-3, or the challenging Cycle Stack. iStack’s built-in StackMat works just like the real thing by timing your stacking and storing your 10 fastest times for each of the 3 stacks. The iStack timer can even be used to time yourself when stacking with real Speed Stacks cups.

So that your best stacking times can be compared with others, iStack only allows you to stack using the official WSSA sequences but once you have finished the stack, the game goes into free stack mode, which allows you to play around and practice your moves.

iStack has fun sound effects, cool graphics, and lets you choose your cup color and StackMat design. The on screen prompts guide you along the way but if your not sure how to do any of the 3 official stacks, just select one of the six Speed Stacks stacker training sessions from the help screen (Wi-Fi required for training sessions).
