Drag anywhere (or use WASD / arrows) to move your hole.
Anything smaller than the hole tips over and falls in. Every bite makes you bigger, so you can swallow cars, buses and finally whole buildings.
Classic: 2 minutes against 7 rival holes. A bigger hole can eat a smaller one, so hunt the little ones and run from the giants. Highest score wins.
Solo: the city is all yours. Eat as much as you can before time runs out: 50% for ★, 80% for ★★, 100% for ★★★.
Battle: no respawns, and the safe zone shrinks. Stay inside it and be the last hole standing.
