The Blue numbers tell you how many Gold Nuggets are touching the square,
the purple numbers tell you how many Snakes are touching,
and the black numbers mean it's a combination of Gold and Snakes.
Choose
when you think the square has a Gold Nugget.
Choose
when you think it'll be a snake.
Choose
when you're sure it just a numbered square.
