Purejong, as the name suggests, is a free online mahjong game that takes you back to the days when they invented Mahjong. The game had Chinese symbols which were very confusing and made the game more challenging. This is a game that takes you down the path of history, all the way back to when the game was born. In this game, you are to remove two tiles that have identical symbols, by clicking on them. However, this is not so simple because there are slight variations in the symbols which make it harder to tell them apart. You may find a symbol in two parts, where the bottom part is identical, but the top is not. This makes it very complicated and that is why people say that the traditional mahjong is tough. The game is timed so you cannot spend all your time looking for the matching pieces; if you find that you are stuck, you can use the hint button so you can see which the next free tiles that you can remove are. However, you can also undo a move that you did not like if you think it will leave you with fewer moves to make. Remember that all piles are designed to be completed but if you make a few small mistakes, you may end up having no more moves to make. This is a game that will remind you why mahjong was once said to be the ultimate brainteaser or the ultimate puzzle. Many still argue that there are other puzzles tougher than mahjong but enthusiasts beg to differ. So if you have missed the original version of this game, then this is the time for you to go back and enjoy it once again. Take it all in, in its purest form, and cleanest lines; a true work of art and intrigue.
