The puzzle consists of a rectangular grid of any size divided into regions. The goal is to draw a single continuous non-intersecting loop that connects the centres of the grid cells. The loop must visit each region exactly once. The number in a region indicates how many cells of this region are visited by the loop. In regions without a number the loop may visit any number of cells. If the loop does not visit any two neighbouring cells, these cells must be in the same region. math puzzles for kids - math puzzles and brainteasers grades 6-8 - math puzzles and brainteasers grades 3-5 - math puzzle books for kids age 9 12 - math puzzle books for kids 5-8 yrs - math puzzle books for kids - math puzzle for kids - logic puzzles for kids age 10 to 13 - logic puzzles for kids ages 8-10 - logic puzzle books for kids age 9 12 - logic puzzle book for kids - logic puzzle for kids - logic puzzle for teens - logic puzzle kids
