Tracing a path with a pencil through a printed maze of walls and passages, from a marked entrance to a marked exit, without crossing any walls or backtracking through dead ends.
A picture puzzle where a combination of images, letters, and symbols stands for the sounds or words of a hidden phrase — for example an eye, a heart, and the letter U together spelling "I love you".
A grid-division puzzle where you split the whole grid into regions (polyominoes) so that every cell's number equals the size of the region it belongs to — and no two same-sized regions touch edge-to-edge.
