Grid Maker

A prototype of a logic-grid puzzle editor.

Creating puzzles

The tool loads with a random grid of item names but with no clues. Check the Edit Puzzle checkbox in the toolbox at the top right to edit the item names or add clues. The Categories and Items/Category numbers let you change the size of the grid.

Solving puzzles

Click a cell to toggle through O/X/question/blank, shift+click to cycle in reverse order. For convenience of pivoting elements over, you can Alt+click to freeze/unfreeze the highlight. Control+click an O to auto-pivot elements between those two categories.

Click clues to toggle them being struck through and moved below active clues.
