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 you're 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 you're playing alone then you can try for your best time.
