Hmm. Good thinking. But in case your first click lands in a dense field, that method won't cut a notch in the fabric for you to chisel at. Like a dummy, I'm taking the waiter-pulling-tablecloth-off approach here, but lets see if I get stuck on it.
If you read up on classic Minesweeper, that's what they do, is if your first click is a mine it relocates it to the first open spot off the top left corner.
It's also why you shouldn't click in the top left corner in the game if you're hoping for a good cascade, because you're less likely to get one.
