Here is a fresh new puzzle! 96 pieces with the "vintage" shape and a quote in mystery mode. It's pretty hard, especially when you don't know the image you are working. Watch the letters, that may give you some hints.
With the new version 5.8 the ranking of that puzzle is active so you can go into a "competitive mood" and compare how you do against other players: By default, at the end of the game it will display the score box at the bottom showing the time spent and your position in the ranking for the puzzle. Click the box and you will be offered some more options. Make sure to set an Alias to identify you and push the button to view the ranking.
Enjoy and feel free to invite friends to do this puzzle (it's free, they only need to install the trial program)
