Dropolis Hole

The ground under Dropolis has started to give way, and four sinkholes are racing through the streets. Yours is the amber one. In ninety seconds the city decides which hole ate the most of it.

Steer a hole through a small city and swallow everything smaller than you, from traffic cones to towers, before the 90 second clock runs out.

Drag anywhere on the screen to steer the hole, like a joystick; on a keyboard use WASD or the arrow keys. Anything smaller than the hole tips over the edge and falls in, and every object adds to your size. The hole grows in steps, and each step lets you swallow bigger things: benches and street trees first, then cars, kiosks, buses, houses and finally tall buildings. Three rival holes roam the same streets. A clearly bigger hole swallows a smaller one, so eat rivals once you outgrow them and run from the ones that outgrow you: if a rival swallows you, the run ends. Arrows at the screen edge show where the rivals are. Your score is the total mass you swallow; the daily challenge gives everyone the same city. Finishing a round in first place opens hard mode, where the rival holes are faster and pick their food better.
