Lost games – Mathdoku+ Sudoku Style Math & Logic Puzzle Game Review

Revised. Lost another puzzle of work. Was about 80% complete. Did not turn off my iPad. Just put to sleep. Go back to the game and find a blank puzzle. The developer website has no mention of this game. Play the game but don't support the developer. Poor poor interface. I love kenken and these are good puzzles. The problem is that if you stop a puzzle and come back to it, all your previous work is gone. You have a blank puzzle. I've taken to taking screen shots each time I stop a puzzle. I can't sit and an 8X8 or 9X9 puzzle in one sitting. I've got work to do. Please fix this problem.
