Hard As Nails - 5 in 1 Nail Puzzle Box Set

 Difficulty Level 1 to 5

Professor Puzzle's 5-in-1 Nail Puzzle Box Set contains five nail-based brain-teasers. Not for the faint hearted these devilish devices are more difficult than herding cats. Much more fun than any nail based DIY you can imagine, this infuriatingly difficult puzzle pack includes:

• The Nail Biter: This puzzle is based on the centuries old classic bent nails puzzle. Nobody is sure where the puzzle was invented, but it has been amazing puzzlers ever since with its hair-tearing mix of difficulty and simplicity. This version has an added twist to make it doubly difficult to solve.
• Nail Jail: Slightly more difficult than the Nail Biter. The simplicity of this puzzle is well hidden, so it takes longer for even the most seasoned puzzler to get to grips with the mechanics of it.
• S-Nail: If you manage to separate these two nails reasonably quickly don't be too quick to congratulate yourself. The fun really starts when you have to find a way to get them back together again. This puzzle is cunningly tricky to get to grips with.
• The Last Nail in the Coffin: The most difficult of the four disentanglement puzzles. Two operations are required to separate and then reattach these nails. Only suitable for the more gifted puzzler.
• The Bed of Nails: The Bed of Nails is the ultimate nail puzzle. Only when this puzzle has been solved without opening the clues booklet or the solutions booklet can you claim to be a true master of Professor Puzzle nail puzzles.

This box set would make a great gift for someone or just as a challenge for yourself.
