As any builder will tell you, 6 inch nails are too big for any practical purpose - that is of course unless you want to build one of the greatest puzzle compendiums ever invented.

With 5 different levels of difficulty, the first 4 follow the same rule - just take them apart. Sounds simple? Maybe, but these cunningly designed metallic marvels are more challenging then rubbing your stomach whilst patting your head and being fed a sticky donut...and not being able to lick your lips - very challenging indeed!

The fifth level is a totally different idea with a twist that, if you crack it, will make you very smug indeed. A sealed clues booklet and a sealed solutions booklet are enclosed for when you have conceded defeat - almost inevitable.

Diehards will no doubt endeavour to solve all 5 and be a true nail puzzle master, but be warned - it could take less time to straighten all the nails and use them to build a shed!
