Here's MineSweeper in action:
You know the game by now... mines are marked by tapping the flag mode control, bottom left - if you forget to do this or tap on a wrong square to clear it by mistake then it's explosion time!
The + and - controls zoom the playing field in and out, seemingly without limit. Here I'm zoomed in way too much (and could go further) and zoomed out way too much (and again can go further, to the point where the playing field disappears altogether)! Cool, though you'll only ever need 2 or 3 of the zoom levels...
A simple help pane, if you need it (you won't) and (right) I've triumphed again in the battle of mind over mines...
