Reveal the Rectangle!

Enter your guess coordinates in x,y format. The rectangle you are looking for is at least 4 units wide.

• = rectangle corner
• = rectangle border
• = inside of rectangle
• = outside of rectangle

This game is based on an idea from an old teacher book I had. It promotes critical thinking (logic) as well as giving students opportunities to practice graphing on coordinate planes.

When entering coordinates, spaces do not matter. Also, you can just push "ENTER" on the keyboard instead of pushing the "Guess" button.
