# Stained Glass

Fractions of area · 30 levels

Glaze each pane so every colour fills its fraction.

## How to play

- Pick a glass colour, then tap panes to glaze them. Tap a pane in the same colour again to clear it.
- Panes that share a lead line must be different colours. (Touching at a corner is fine.)
- Each colour must cover exactly its fraction of the whole window. A triangle is half its box.

Turn each fraction into squares first: ¼ of a 16-square window is 4 squares. From level 20 the pane sizes are hidden, so count the faint grid.
