Sudomathania

Sudoku and arithmetic, in three dimensions.

  1. The cube is 4 × 4 × 4. Every row, every column and every pillar of four cells must contain 1, 2, 3 and 4 — each exactly once. Three directions, not two.
  2. Cells are grouped into outlined cages. A cage shows a target and an operation: 12× means its values multiply to 12, 3− means they differ by 3.
  3. Drag to rotate the cube. Click a cell, then press 1–4. Arrow keys move, Q/E change layer, Backspace erases.
  4. Every puzzle has exactly one solution, and it is always reachable by reasoning alone. No guessing is ever required.
