Too many solutions & no notes
The ability to take notes is necessary to solve this type of puzzle. I’ve had to recreate the puzzle by hand, but even then the puzzles have either not enough information to solve without guessing or have more than one solution.
Needs pencil marks
Clean and simple, but definitely needs a pencil option. Also, I would prefer an undo option as apposes to a complete revert to start button.
Needs a pencil option
I love this puzzle and I like the design of the app, but it really needs a pencil option.
Garbage
Only 5x5 is available. Can't pencil in numbers. There are much better versions out there.
Yes and no
So happy to have found my favorite type of number puzzle in app-form. On the other hand, really wish there was a "pencil in" option and a way to check progress as you go. As it stands, it is fun and satisfying to a point but would pay for above-mentioned upgrades.
