Each new tile you add gives you a different and more challenging puzzle.
You may not find the first loop hard...but only the best can solve all ten!
This puzzle keeps on going no matter how many additional packs of 10 tiles are added into play.
Available in black tiles w/metal case or green tiles w/wood case (either/or may be shipped with each order).
Tantrix Discovery Solitaire includes 10 bakelite tiles, wood or wood & metal storage platform, and instructions.
