Seems to have a fatal bug – New Sudoku Free - My Live Number Math Place Russe Puzzle Game Review

I love sudoku, but this one doesn't let me finish any of the puzzles. I get part way through and it tells me I won the game. I usually have only managed to place 5 or 6 numbers. Please fix. I can't wait to keep playing and upgrade my rating.
