But they can only 16 at a time, and they must cross many obstacles that require logic to get past. When the Zoombinis home, Zoombini Isle, is taken over by creatures called Bloats, they decide to escape to a new home. For example, in the puzzle ‘Allergic Cliffs’, the player is given a choice of 2 bridges, each of which will allow Zoombinis to pass only if they have certain combinations of features. Most of the puzzles involve the physical features of the Zoombinis as part of the solution. The game depicts the Zoombinis’ search for a new home, featuring a variety of logical puzzles which the player must solve to get the Zoombinis to their new home. However, they are tricked and enslaved by their neighbors, the Bloats. The Zoombinis are a race of small blue creatures depicted with varying facial features, initially living in prosperous peace on a small island called Zoombini Isle.

Logical Journey of the Zoombinis (also known as Zoombinis Logical Journey in the remake) is an educational puzzle computer game developed and published by Brøderbund Software for the original and The Learning Company for the remake.
