The puzzles of Tau Heximus introduce Power Gems, and a brief tutorial regarding this type of Special Gem is given upon accessing the planet for the first time. All the puzzles are arranged in various formations and patterns. The first, fourth, and fifth puzzles contain a Power Gem.
Completing any four of Tau Heximus' five puzzles unlocks Ceti Alpha V, the next planet in Puzzle mode.
- The tutorial that is given upon accessing Tau Heximus for the first time strangely features three blue gems arranged in a column, something that is not possible in normal gameplay.
