Rhombic 3 Maze Generator — Free Online Tool
The geometry
Rhombic 3 is the most intricate of the diamond-grid mazes, packing in the maximum diagonal branching so that corridors fork, double back, and dead-end far more often. The angled geometry already disorients the eye; this variant compounds it into a genuinely demanding solve.
How it works
By increasing how densely the diamond cells interconnect, Variant 3 raises the number of choices at each junction and, with it, the difficulty — all without needing a larger grid, so it stays compact on the printed page. The compiled C/C++ engine carves it in milliseconds and renders every angled wall sharply at 300 DPI. Full control over size, colour, and stroke weight keeps even this complex maze readable in print, whether it appears as a small inset or a full-page brain-teaser.
Who it's for
Rhombic 3 is ideal for the hardest tier of a KDP maze book, where buyers specifically want puzzles that resist quick solving and reward persistence. Educators deploy it to push advanced students beyond ordinary grids and into genuinely demanding spatial reasoning. Game designers mine its dense diagonal branching for striking, maze-like level art that photographs well in promotional shots. Sample it free, or upgrade for all 30 styles plus 300 DPI PDF and batch export.
Rhombic 3 vs. a classic orthogonal maze
| Attribute | Rhombic 3 | Orthogonal (square grid) |
