Bad Game Design – Sudoku on Chalkboard Review

I like the concept, however, the game screen on an iPhone is hard to use. The options screen has such small print it is hard to read. Also, there is no easy way to remove a number once entered. The Sudoku games created aren't symmetric. Then the ads kick in every few turns, so playing a game is very annoying! There isn't even a purchase option for "Remove Ads".
