Leg 1a - Allergic Cliffs Difficulty: Not So Easy Puzzle type -- Logic, Set theory. There are two bridges hanging over a cliff supported by six wooden pegs. The Zoombinis can only cross one of the bridges, and the bridge they are allowed to cross is determined by their characteristics. If the wrong bridge is selected, the face embedded in the cliff will have an allergic reaction and the Zoombini will be sent tumbling or flying back to the other side. As a result, a peg will spring loose and drop down the cliff. If all six pegs come loose, the bridges will collapse onto the faces and the Zoombinis who did not make it to the other side will be stranded, unable to cross between the cliffs. Assuming the player actually moves the same Zoombini to each of the two bridges (where the first bridge was wrong and the second bridge is the correct one), the player is guaranteed five Zoombinis to the other side.
