FIX THE PROBLEM WITH THE SOLVE BUTTON!!!!!!!!!!!!!!!!!!!! – Sudoku - The Game Review

I would give more stars, its worthy of a five star rating if when I tap the solve button it would either solve the puzzle or not continuously run for HOURS on end!!!!!!!! I have to wait at least 12 hours before I can play another puzzle!!!!!!!!!!! I only keep this app because the others are plagued with advertisements, however I'm getting ready to dump this and deal with something else!!!!!! FIX THIS PLEASE!!!
