Tetrobot and Co.

Maya is the youngest person to ever graduate from college in Sweden. She’s an engineer, and people from around the world are sending her their Tetrobots (tiny robots that look like washing machines) for repair. Maya has created a microscopic robot called a Psychobot that she injects inside the Tetrobots. Then, she can control the Psychobot remotely, moving it through the Tetrobot to fix all of its microscopic problems.

As she works, Maya discovers strange photographs of herself stored in the memories of the Tetrobots she’s repairing. She also receives occasional cryptic letters from her friends, Alexey and Markus, about a new project on which they’ve been working.

The story plays a relatively small role in the game. Mostly, players will be spending their time solving tricky puzzles.

Tetrobot and Co. saves after each level is completed. If you leave partway through a level, you'll have to start over from the beginning.

The puzzles of Tetrobot and Co. can be extremely challenging, but most of them are optional.

• How did you solve that puzzle?
• Why do you think there are more boy scientists than girl scientists?
• What uses might robots serve in the real world?
