ONE CLEAR WAY TO PLAY

A fraction is part of one whole.

  1. Read the mission. Start to finish is one whole river stretch. The bottom number tells you how many equal parts it has.
  2. Make the pieces match. On Medium and Hard, press the gold button to see the same distances split into smaller, equal parts.
  3. Move your otter. Use the slider or Back / Forward buttons. The top number counts how many parts you travel.
  4. Check your destination. Take your time. A wrong stop comes with an explanation and another try.
