Think you are too smart? The Rubik cube and Sudoku seem to small a challenge? Well get ready to crack the code with the Isis Ball. A mind puzzle that you solve by opening an alloy ball that is constructed in layers and covered in hieroglyphics. Promising that each Isis ball is unique and requires a different combination to open it, it seems quite challenging. If and when you crack the combination and you'll reveal a special key inside, that has a number stamped on it. The key will open one of the ISIS golden pyramids, which are hidden in secret locations throughout the UK. Each pyramid contains a gold coin worth £500 and a number of silver coins worth £20 each!

An adventure that is a race against time, you can get clues from the games' website to help them in their quest to unlock the mystery and find the hidden treasure. This is the first in a series of 5 ISIS puzzles to be launched, each presenting more advanced and challenging stages than the previous one. The Isis ball costs £99.95 ($191)
