They're the Logic Link Puzzles kids love but a more game-like form! This set includes 166 puzzles at various levels and 32 small plastic, colored game chips. Each puzzle is presented on a 5" x 5" puzzle card and uses a series of clues to instruct a player where to place chips to solve the puzzle, requiring deductive reasoning and determination. The cards are double-sided, with a puzzle on both sides, and while outlines show where to place the game chips, instructions tell where to put specific colors (i.e. the green chip is adjacent to the yellow chip, the red chip touches only yellow chips, the topmost chip touches the blue chip, etc.). Beginner puzzles form a single row of chips and usually have two clues; intermediate puzzles form a rectangle and require 4-6 clues; advanced puzzles form a square of three rows and usually have 7-8 clues; and expert puzzles form a circle of chips, with 5-8 clues. Cards are color-coded by difficulty and the game is stored in a cardboard box.
