Horrible Interface – Mathdoku+ Sudoku Style Math & Logic Puzzle Game Review

The interface for marking possible values is terrible. We need to be able to select more than one square and mark all of them at once. Even marking one square with several candidates is too hard. Please fix this. Otherwise, the app is good and the game is fun.
