THE MAZE (see drawing page E)
WHO WILL FIND HIS WAY OUT FIRST?
To decide who starts playing first, each player should press *
(the tables key), then I, and note the base number that appears.
Whoever gets the greatest base number goes first.
The base number also indicates each player's departure point in
the maze.
Look for your departure point and place your marker on it.
The first player moves his marker along the maze until he comes
across an obstacle.
He can only cross this obstacle by correctly answering a question
based on the operation sign shown in the obstacle.
You have only one chance to get the right answer.
If your answer is wrong, stay where you are.
It is your opponent's turn to move.
