Survival is a two-minute storm challenge: evaporate 150 water with Sun
before the clock ends. Keep overflow below the limit. The sky gets
wilder every 40 seconds.
01
Read the forecast
Blue marked tiles show where the next 3 × 3 downpour will land.
Build earth walls or carve a retaining basin before it arrives.
Timed pieces land at your cursor.
02
Clear whole lakes
Aim Sun at any wet tile to evaporate its entire connected lake.
Bigger lakes earn larger bonuses. Clear another within 12 seconds to
build a scoring chain.
03
Make a real basin
Crater digs a 3 × 3 bowl and raises a retaining rim around it.
Channels lower the land without a rim: use them to connect water, or
create an escape route. Sandbox has no clock or storms.
