Get through an underwater maze by solving equations using the binary system.

In the game, you must get to the end of a water-filled maze. Put on your wetsuit and head into the maze. To orient yourself, you must solve the sums in binary code. Record your answers on the dashboard and find the corresponding colour to determine which direction to take.

In the game, you must get to the end of a water-filled maze. You will need help to get out, so here’s a hint. You probably know that computers speak in binary. For them, 1 means the current flows and 0 means it doesn’t. In binary, a 0 or a 1 is called a “bit.” A group of four bits can express the numbers 0 to 15. Larger numbers require groups of 8, 16 or 32 bits (or more).

To count in binary, you use a carry digit, just like in the decimal system. Record your answer on the dashboard. The correct answer will indicate which direction to take.
