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.
