Turn a layer. Connect equal numbers.
-
Turn a layer
Swipe on the cube to turn a whole layer, the way you would on a puzzle cube.
-
Merge at the edge
Matching numbers across the edge of the layer you turned merge into a larger one: two 2s make a 4, two 4s make an 8.
-
Look around
Rotate your view to explore all six faces of the cube and plan your next move.
-
Use a boost
Clear a tile, double a number, swap numbers or reshuffle the cube. Which boosts you get depends on the mode.
A hands-on course guides you through turning, merging and using boosts, right on the cube. You can revisit the lessons any time in How to Play.
