Manic Minefields X for Mac

From Norbyte:

Manic Minefields is really 12 pumped up minesweeping games in one, as it features 12 uniquely designed minefields with beautiful graphics and crisp sound effects, to choose from. Some of the minefields have special rules (i.e. obstacles), and some have different ways of displaying the numbers (i.e. dice, Roman numerals, foot prints etc.). Other features include a marathon mode, 4 sizes, a hint/help function and import/export best times.
