Most cube solvers just spit out a list of moves. This one teaches you. Enter the colors of YOUR scrambled cube, and an animated 3D cube shows exactly how to hold it, which face to turn and why. For every situation, you see the formula and a before/after picture. Learn Layer by Layer (classic or retro textbook style), CFOP 2-look and 1-look, or solve in ~20 moves. Picture cheat sheets, 8 languages, works in any browser on phone, tablet or PC.
This is a game for fun among friends: guess the match outcome (1-X-2) and try to build the longest streak of correct predictions in a row. No real money — just virtual coins and a chance to compete for the title. Whoever is the first to reach 10 wins in a row gets a crown. You can invite friends and earn bonuses for it. On first launch, you'll need to grant a Google permission. Built as a hobby project on Google Apps Script, still in beta.
