BlockuDoku – Blockudoku - Block Puzzle Review

I love the game! Contest center October 29 at 5AM! At 1:30 I was in first place. Neck and neck w 2 other players! Went to see how it ended and screen is frozen and can’t get back to play game! This also happened about a month ago and had to delete game and reinstall! Can you fix this or do I have to keep deleting and reinstalling?
