Tap on any square full of beans. If the number underneath it is a 0, that's a cause for celebration, as there were no greens hiding under there. If the number is a 1, that means there is 1 green hiding in the surrounding eight squares. The higher the numbers, the higher the risk of you eating a gross grubby green!! So stick to the beans, and leave the greens hiding where they are. Work your way up from a small bowl of beans to a whole screen FULL of them, and don't mind the occasional botty-squeak you might hear along the way.
