What kinds of mazes are there?

In "The mazes" card, "Kind of maze":

• Square: the classic.
• Round: rings around a centre; the way in is on the edge, the goal in the middle.
• Hexagonal: a honeycomb, six ways out of every cell.
• Triangular: zigzag corridors that never run straight for long.
• Organic (irregular cells): cells of different shapes, different in every maze.
• Octagons and squares: big octagons with small squares between them.
• Pentagons (Cairo tiling): every cell a five-sided stone.
• Weave (bridges and tunnels): paths cross over and under each other.
• Shaped (silhouettes): every maze inside a picture.
• Letters (an alphabet or a name): every maze inside a letter.
• Hidden picture (the way draws it): color the way through and a picture appears.
• Mixed (a different grid each page).
