CubeSensei
Learn the Rubik's Cube with a patient mentor and bite-sized practice.
Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, praises, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.
#FFA726 CubeSensei is an app that teaches you how to solve a Rubik's Cube — and **27 other puzzles** too! You'll start with the basics and work your way up to speedcubing, magic tricks, adventure games, and even the math behind it all.
