Penny Dell magazine Logic Puzzles for the true logic problem fanatic. Try before you buy with the first ten puzzles included free with all features enabled and never any ads, nags or spyware. If you like it, thirteen more volumes are available for purchase, each with thirty unique puzzles, for hours of puzzling fun.

Keep your mind sharp with these stimulating logic problems that will exercise your brain muscles – a great introduction to deductive reasoning! Enjoy a range of problems in every volume.

No more erasing! Multi-level undo and Auto-X let you focus on the logic. If you get stuck, you can choose to erase errors, get a logical hint, or view the full hand-worked solution (just like the magazines).

Works best on larger screens, but you can zoom the grid to fit your screen – from phone size to the largest tablet.
