Some puzzles have multiple solutions, but only one solution is recognised as correct. This and not being able to mark as on/off instead of on/unknown/off makes this app frustrating. With some work this app could become a fun game. It hasn't been updated in over a year, so I have little hope that it will be fixed.
It would be an alright game if you were allowed to review boards after you beat them, instead of what happens which is the immediate return to the main menu.
I find the gameplay easy to use, but it's frustrating when you appear to have more puzzles after the initial 50, and they're unsolvable.
Force closes every time I try to start a puzzle.
The puzzles are good, though the grid mazes at 7x7. Clean, simple design, but the way that the game just ends when you solve the puzzle is a bit jarring. Excellent for a quick, unchallenging game.
Unless I'm just missing it, there is no way to mark cells that you know will be white. A key way of making logical moves...
Cannot mark the white cells.
