Caterpillar Logic is a free puzzle game developed by Fuks Michael for Android devices. The game is similar to Zendo and requires players to guess the rule that describes a subset of sequences of multicolored segments or caterpillars.

The game is designed with multiple levels of increasing difficulty, and each level presents a new set of caterpillars that follow a specific rule. Players have to use deductive reasoning to determine the pattern that the caterpillars follow and then apply it to new sets of caterpillars to solve the puzzle. Caterpillar Logic was originally written for the Kivy Programming Contest 2014 and was nominated for the "best app idea" award.
