3927

Instead of a flat grid you slide a 3x3x3 cube in any of six directions, up, down, left, right, in or out. When three tiles of the same value line up they fuse into the next power of three: three 3s become a 9, three 9s become a 27, and on up. Cascades can chain across axes. Rotate the cube to see through it and plan your merges.

• Shifts move every tile in the chosen direction across all layers.
• Three equal tiles in a line merge into the next power of three.
• Rotate the view to read the back faces before committing a slide.

• Desktop: Arrow keys and WASD to shift; drag or hold to rotate the cube; Space to act.
• Phone & tablet: swipe to shift and drag to rotate the cube.

• Daily seeded cube shared by everyone.
• Practice with fresh cubes.

• Keep your biggest tiles clustered in one corner of the cube so triples can form near them.
• Use rotation to scout hidden tiles before a shift buries a near-complete triple.

3927 takes the sliding number-merge puzzle into three dimensions with triple-fusion and multi-axis cascades. An original, free browser game made in-house at PlayPendium.

1. Is 3927 harder than 2048?

   A state-space showdown between a flat grid of twos and a cube built entirely out of threes.
2. Luck, Skill, and the Clock

   Every shift that changes the cube drops a new random 3 into it. So every run is part craft, part weather, and the leaderboard settles ties by who finished fastest.
3. A Perfect Strategy?

   Two merge games, one question: can either be played flawlessly? The answer runs through the corner of a board, an opponent who never arrives, and a number seventeen exponents tall.
4. Reading a 3-D Number Stack

   3927's hardest problem was never its rules. It was letting a human read twenty-seven numbers arranged in depth, including the one they can't see.
5. Why Threes

   The hidden efficiency of base three, and whether a game built on it is quietly the more elegant machine.
