Minesweeper with deterministically solvable boards

[adamn]

Hello,
I've made recently a Minesweeper game which can be found here: http://minesweeper-pro.com/
The game has the following features:

• There is an option to play only boards that are deterministically solvable (that is you never have to guess),
• There is a solver which gives you a hint (after you press h),
• The game has two additional board sizes (50x50, 100x100),
• The game has extensive system of statistics,
• The game can be played on touch devices.

I will be grateful for any comments and feedback.

Its not bad except there are a few minor issues. The biggest one being no way to turn off marking a square with a "?", and the images are a bit blurry.
