Snake (also known as "Tunnel") is a kind of logic puzzles. It is played on a rectangular or square grid, where two cells are marked. The task is to draw a single line ("snake") between marked cells; this line never touches itself, not even diagonally. Numbers outside the grid show how many cells must be blackened in the corresponding row or column. ============ KEYWORDS/TAGS: logic games - logic game puzzle - logic puzzles - logic puzzle books for adults - logic puzzle books for teens - logic puzzle for adults - logic puzzles riddles - brainteasers for adults - brainteaser puzzles for adults - brainteaser books for adults - brainteaser adults - brainteaser for adults - brainteaser games for adults - brainteaser jigsaw puzzles - logic puzzle large print
