Tantrix Discovery Puzzle

The hexagon shaped tiles are numbered on the back and have bands of color on the front. Tiles 1, 2 and 3 are numbered in yellow which mean you must form a yellow loop using those three tiles. Tile number 4 is marked in red, so you must rearrange the four tiles in play to create a red loop. The challenge increases the more tiles are added. Includes 1 wooden or metal holder, 10 Tantrix tiles in either black or green (chosen at random), and instructions. For ages 8+
