Gnomes are a surly bunch, and although they're out to get you, that doesn't mean they don't have quarrels of their own or that they're ready to forget past grievances. Gnomes stream through your garden down a number of twisting paths that cross each other at various points. Your mouse is a cat who can hold gnomes at bay, but only in one lane at a time. The trick is to hold up some gnomes so that when you do let them progress they'll run into other gnomes at the intersections. When two gnomes collide, they get into a terrible kerfuffle and remove themselves from the game. It's like having a continuous plinko machine that you're trying to jam. Players are scored on the number of gnomes they let through and bonuses are given out for special events like getting 3+ gnomes to collide at once.
