Logic Puzzles For Teens : Tetroid Puzzles

Tetroid is a logic puzzle invented by Naoki Inaba (Japan). A rectangular or square grid contains black cells. The aim is to divide the grid into regions of exactly four cells, to form an L, I, T, S or O tetromino. Black cells do not belong to any tetromino. The tetrominoes may be rotated or mirrored. When two tetrominoes in adjacent regions share an edge, they must not be of the same type. ============ 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
