Kids Logic Puzzles: Masyu Puzzles

(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. The loop must "enter" each cell it passes through from the center of one of its four sides and "exit" from a different side; all turns are therefore 90 degrees.The two varieties of circle have differing requirements for how the loop must pass through them:• White circles must be travelled straight through, but the loop must turn in the previous and/or next cell in its path; • Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path. ============KEYWORDS/TAGS: logic puzzle books for kids - easy logic puzzles - logic puzzle 12 year old - brain teasers for kids ages 10-12 - brain teasers for teens - brain teasers for kids - brain teaser for teens - brain teaser games for teens - brain teaser games for kids - brain teaser kids - brain teaser puzzles for teens - brain teaser puzzles for kids - brain teaser 12 year old - logic puzzle books for teens
