Masyu (also known as "Shiroshinju Kuroshinju," "White pearls and black pearls") is a type of logic puzzle. It is played on a rectangular grid of squares, some of which contain circles; each circle is either "white" (empty) or "black" (filled). The goal is to draw a single continuous non-intersecting loop that properly passes through all circled cells.

Tents ("Tents and Trees") is a logic puzzle invented by Léon Balmaekers (Netherlands). The task is a grid of squares, some of them contain trees. The goal is to place tents in some of the remaining squares, in such a way that the following conditions are met: - There are exactly as many tents as trees. - The tents and trees can be matched up in such a way that each tent is directly adjacent (horizontally or vertically, but not diagonally) to its own tree. However, a tent may be adjacent to other trees as well as its own. - No two tents are adjacent horizontally, vertically or diagonally. - The number of tents in each row, and in each column, matches the numbers given round the sides of the grid. math brain teasers for kids - brain teaser games for kids - mind puzzles for kids - brain puzzles for kids - brain teasers for kids with answers - maths riddles and puzzles - simple brain teasers - brain games for kids - brain twister puzzle - riddles and brain teasers with answers - best brain teaser games - logic puzzles with answers - challenging puzzle games - brain teasers for children
