How to play Glyphs
Glyphs is a wordless logic puzzle. Six symbols, one grid: place each symbol so that no row, column or diagonal ever holds the same symbol twice. There is nothing to read and nothing to translate — logic is the whole game.
The rules
Place each symbol exactly once in every row and every column. Some symbols are given at the start and cannot be changed.
A symbol may never appear twice along the same diagonal. Diagonals run straight through black squares, so two cells can conflict even with a block between them.
Black squares stay empty, and some open cells stay blank too — when no symbol fits a cell without a conflict, blank is the correct answer.
Controls
Select a symbol in the palette, then tap a cell to place it. Tap a filled cell to cycle through the symbols, or use the erase tool to clear your own entries — the given symbols always stay. The grid marks conflicts as you play, so you see a mistake the moment you make it.
An example
Suppose a row already shows Alpha and Beta, and the open cell you are looking at shares a diagonal with a Gamma. Alpha and Beta are out by the row rule, Gamma is out by the diagonal rule — so the cell takes one of the remaining symbols, or stays blank if each of them conflicts somewhere else.
Tips
Start where the given symbols are densest. A row or column that already holds several symbols leaves few choices for its empty cells.
Check both diagonals before you commit a symbol — the row and column may allow it while a distant diagonal forbids it.
