You can try here. http://www.puzzles.com/projects/logicproblems.html
The interface is pretty easy but you not only have to fill out the grid but the table as well. So no not the same as here but you will find more difficult puzzles then here. I wish this site would get more difficult puzzles. I have also seen a few of those puzzles that you have to guess at. Hope you like the puzzles on the website I posted.
