Got a Rubik's cube that's been sitting scrambled in a drawer for months? We'll show you how to solve it, step by step, on your very own cube. And once you've done it, the real fun starts, because every day you'll get a little bit faster. Best of all, everything in CubersDen is free. There's no subscription, no ads and no paid levels, and every feature you read about below is there for everyone. FIRST, SOLVE IT FOR THE FIRST TIME Show your cube to the camera or paint the colours in with your finger, and CubersDen walks you home from exactly where your cube is right now. We split the beginner method into eight steps. Each one is explained in plain words first, then shown on a 3D cube you can spin around, and then you practise it on the cube on screen or on your real one. Stuck? We'll tell you where to look. It all works offline too. THEN A LITTLE FASTER EVERY DAY The timer has WCA-style inspection, +2 and DNF penalties and scrambles for eleven events, and your stats show how you're improving: averages of 5, 12 and 100, personal bests and charts. The new daily streak keeps a cube in your hands every day. Your flame grows with each day, a week in a row earns you a rest day that saves your streak on its own, and when today is still empty, your phone gives you a nudge. SMART CUBES, A COACH AND ALGORITHMS Got a GAN, MoYu or QiYi smart cube? Connect it over Bluetooth and the timer starts with your first turn and stops the moment the cube is solved. Every one of those solves goes to the coach on cubersden.com, which looks through your recent solves and tells you straight what costs you the most time: a long cross, pauses between F2L pairs, or a PLL you still do in two steps. It also tells you which algorithm to learn next to win back the most seconds. The algorithm trainer in the app has all 57 OLL cases, all 21 PLLs and the F2L cases, and it schedules your reviews so each algorithm comes back just as it starts slipping from memory. EVEN BETTER WITH OTHERS Every week there's a competition with the same scrambles for everyone. You can play a 1v1 battle, open a room for your friends, or race the ghost of your own best solve. And when you fancy something completely different, fire up Rush, a game of quick moves against the clock. THE SAME CUBE EVERYWHERE Your solves, streaks and progress are the same on iPhone, iPad, Apple Watch, Apple TV and cubersden.com. The app speaks English and eight other languages, and it's free with no ads. Start as a guest and make an account later if you like. You can delete your account and everything in it from inside the app: You → Settings → Delete Account.
