- Magic also has a very powerful playing interface - big numpad buttons for two-humbed play, undo/redo, a nice pencil mode(the numpad buttons even change colour depending on which numbers have been pencilled in), movable highlights for the current box, row and column. It is actually better than most playing UI's, even for dedicated sudoku playing apps. Grab's playing UI is a bit simpler.
- Grab has skins for the playing UI (you can change colour schemes) and an animated main menu.
- Magic scores the puzzle for you when you capture (e.g. 4832 - hard), which is cool if you want to beat your personal best. As a bonus, the checking screen (where you can fix digits) doubles as a puzzle editor/creator. You can add/remove numbers and see how the difficulty score compares in real-time. It also tells you if the puzzle is unsolvable (e.g. due to multiple or invalid solutions) :-)
- The capture process for Magic looks much nicer (a spinning cube + music rather than a progress bar) and seems more reliable but you can't adjust the grid boundaries.
