About Lexatetrahedra
Lexatetrahedra is a word and logic puzzle in which you rotate 3D tetrahedra, each with three letters, to reveal everyday English words with patterns that don't fit other word games. Each puzzle has one solution and no word ever repeats. It has 30 handcrafted levels and a quick Word of the Day challenge, with a 1980s look and sound. It is free and supported by ads, and it uses the same concept as Lexiblox, Brian Krause's harder paid game, with entirely different puzzles.
Version 1.05 (3 November) made it ready for iPhone Duo, its release notes say. Adducive hasn't shown the Duo layout, so the picture here is its iPad layout.
