5 STARS by Totoro. Flawless Implementation of the Logic Puzzle on Tablets. This is exactly what I was hoping it would be when I purchased the game. I works exactly like the pen-and-paper version of the puzzles and provides a good spectrum of difficulty. The best feature is the ability to "remove mistakes" from the playfield. Since I never make any mistakes(lol), it can also be used to "reassure" you that you aren't going down the wrong path if you get stuck.

5 STARS by Suzy D. I've been looking for exactly this game for a year now. This type of logic puzzle was just waiting for a tech boost -- automatic fill-in, and no dreaded erasing! The interface is perfect: the controls are intuitive, and there's even a note section for when it helps to get your thoughts in order.

5 STARS by Mutation600. I've been waiting years for a decent Logic Problems app to show and its finally here. Used to play the old Dell logic problem books when I was younger and loved every minute of it. Great job guys!!!!

Logic Puzzles are popular preparation for the GMAT Logical Reasoning sections and similar deductive exams. Solve these puzzles to keep yourself sharp!

There are 10 backstories and five puzzles for each story that get progressively harder. The 5 puzzles for each story all have a unique solution, clues and statistics. See how your time compares!

Volumes 2-10 are available for in-app purchase. Volumes 2-5 each have another 50 puzzles with 10 new backstories and 5 puzzles for each story that get progressively harder. Volumes 6-10 repeat the backstories and allow you to choose harder or easier puzzles. These will provide HOURS and HOURS more fun!

New variations on each volume have multi-size grids, from 4 cell all the way to up 7 cell grids. Look for the "Casual" and "Extreme" volumes for these.
