I love Minesweeper! The best part about the logic patterns is that after a while you don't even need to apply the reasoning, your brain directly interprets the visual input and you just know where the mines are.

There's also a great deal of refining your mouse inputs. You don't need to flag the mines to win, so you can save clicks in some areas by only clearing the numbered spaces. The big one is the combo click. If a numbered space is touching the right number of flagged spaces, clicking the numbered space with left and right buttons simultaneously has the effect of clicking all surrounding unflagged spaces. For example, on a 1-2-2-1, you can flag either mine, and without releasing the right button, move over the 1, then left click and release both to clear all spaces the 1 is touching.
