Instructions: Three doors are shown. All the doors are marked with an x or a y. Doors with the same letter have the same number of shapes behind them. The goal is to figure out how many shapes there are altogether. If help is needed, you can click on a door to take a peek. When you click the correct answer, the word "Correct!" will be displayed and all the doors will open.
Press the reset button, or the RETURN or ENTER key to reset the doors.
