Swallow objects. Every object you consume adds to your size, which raises the size limit of what you can swallow next. You progress from traffic cones and bins up through cars and buses to entire buildings over the course of a round.

Yes. Once you are about fifteen percent bigger than a rival hole you can swallow it whole. The same applies to you, so staying smaller than an aggressive rival like the Hunter is dangerous.

Each event changes the rules temporarily. GOLD RUSH doubles all values, RUSH HOUR fills the roads with traffic, BLACKOUT removes the lighting, and TREMOR damages buildings so you can swallow far above your normal size limit. The final twenty seconds are a FEEDING FRENZY.
