How BoltGlyph works (60 seconds)
A nut sort puzzle. Move nuts from bolt to bolt until every bolt holds one colour, and every nut carries a glyph so you can play by shape as well as colour.
1) The rules
Tap a bolt to lift the nuts on top of it, then tap another bolt to thread them on. A nut can only go onto an empty bolt or onto a nut of the same colour, and a bolt holds four. Matching nuts on top travel together.
2) Every level is solvable
All 300 levels were solved by a computer before they shipped, and each solution was replayed move by move under the game's own rules. If you get stuck, it is the board, not the level: undo a few moves or use your hint. The hint even tells you how far back to undo when a board has painted itself into a corner.
3) Winning moves
Keep at least one bolt empty for as long as you can: it is your workbench. Finish a colour before starting the next, and look for nuts buried under a single other colour; one move frees them. Beat par for three stars.
