I am taking you that little island which you can see right in the middle of the sea. I have just been informed by a reliable source that there are 20 very precious diamonds on that island. The same person also told me that you are a very intelligent explorer and you have been to some treasure hunting trips even before this. You will once again need to solve a number of puzzles in order to find the 20 diamonds mysteriously hidden there. The deal is that you will keep 10 diamonds for yourself and I will keep the other 10 for myself. Shall we begin?
