Great Turtle Race app for iPhone and iPad

To race with friends or family, players start on a given signal, either on the same game or different games to compensate for age or ability differences.
The task is to drag cards into their holders and set the allowed operator (+,-,×,÷) so that the total made matches one of the red targets above. Click the tick to check if youre right. A correct answer moves turtle forwards one step.
Once all the targets have floated away a new set is generated. The first player to get their turtle over the finish line wins the race. If youre playing alone then you can try for your best time.
There are nine games to choose from. Just click on the drop-down box to see them all.
