Cube Master puts 76 magic cubes and twisty puzzles on your phone: a twisty puzzle simulator, drawn in 3D and turned with a swipe. It began as a way to try a puzzle before buying it. Now it is also a place to practise, time your solves, and see how 49 of these puzzles are solved, one move at a time. THE PUZZLES • Cubes from 2x2 all the way to 20x20, the classic 3x3 magic cube included • Pyraminx from 2x2 to 10x10, the 4x4 Master Pyraminx among them • Megaminx, Kilominx, Gigaminx and Teraminx • Skewb, Skewb Ultimate, Dino cubes, Redi cube and Fadi cube • Mirror cubes from 2x2 to 7x7, a Mirror Skewb and a Mirror Pyraminx • The Square-1 family: Square-0, Square-1, Square-2, Super Square-1 and Mirror Square-1 • Cuboids: 1x3x3, 2x2x3, 2x3x3 and 3x3x4 • The clock puzzle, with nine clocks on each side • Snake puzzles from 24 to 72 pieces, and a gallery of shapes other players have built and shared • 13 picture cubes, including Sudoku, Earth, Maze, Dice, Food, Number and Arrow cubes STUCK? A GUIDE FOR 49 PUZZLES (NEW IN 2.0) Scramble a puzzle, or turn it any way you like, then ask for the solution. Cube Master draws each move as an arrow on the puzzle itself. • Follow along by hand: turn the face the arrow points to, and the next arrow appears • Turned the wrong way? An orange arrow shows you how to turn back • Or press play and watch the puzzle solve itself, move by move • On cubes, the move notation follows your view of the cube, so the letters match what you see • It solves the puzzle you have on screen, and works it out on your phone, even offline The solver covers cubes from 2x2 to 6x6, Megaminx and Kilominx, Pyraminx up to 6x6 (the Master Pyraminx too), Skewb, Square-1, the mirror cubes up to 5x5, the clock, the picture cubes and more. The giants (7x7 and up, Gigaminx, Teraminx, Pyraminx 7x7 and up) are left for you to solve on your own. PRACTICE AND COMPETE • A solve timer that keeps your fastest time and your average of 5 • World leaderboards for each puzzle, so you can see where your times stand • Undo for the turn you did not mean to make • Scramble any puzzle with one tap • Lock the view while you solve, or turn the whole puzzle around to look at every side If you are a speedcuber, it is a handy cube timer and a way to warm up on a puzzle you left at home. If you are just curious what a Megaminx or a Square-1 feels like, it is a cheap way to find out before you buy one. PREMIUM Cube Master is supported by ads. You can watch a short ad to see a solution. Premium removes the ads, opens the picture cubes and the longer snakes, and gives you as many solutions as you want. • Premium Weekly: an auto-renewing subscription, billed every week • Premium Lifetime: a one-time purchase Payment is charged to your Apple ID at confirmation of purchase. The weekly subscription renews automatically unless it is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within the 24 hours before it ends.

Verdict

The call

The clearest difference is rating: Cube Master at 4.4 against eX's 3.0. Cube Master also leads on ratings volume (434 vs 7). eX's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Cube Master holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Cube Master has 434 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 49% of Cube Master's written reviews are positive against 50% of eX's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cube Master ships an update weekly, eX every 10 days. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
