Minesweeper algorithm

[Coin]

Know when you click on a tile that is blank in minesweeper? How it uncovers all the blank tiles and one layer of numbered tiles beyond that? Anyone know how?

uncovertile(tile)
{
flip(tile)

return unless i'm a 0

for each neighbor_tile
{
if neighbor_tile ain't already flipped
{
uncovertile(neighbor_tile)
}
}
}

You might want to look at ttp://en.wikipedia.org/wiki/Seed_fill. The code I am using is similar to the second algorithm, but much more bloated and doesn't work correctly, so I think I'm gonna use one of the ones shown there.

Thanks both of you.
