Rainherd

You can't dig channels or build pipes. You can only decide where the rain falls.

Herd one rain cloud over a tiny island. Every field needs a good soaking, but water runs downhill, gathers in hollows and races for the sea, and the villages sit right where it gathers. Rain on the wrong slope and a village floods.

• 20 islands: more fields, more villages, then wind that pushes your cloud
• A daily island, new every day
• Save rain for three stars
• Field progress and flood warnings when you want help (turn them off for a challenge)
• Plays in the browser on desktop and phones

Every island is checked by an autopilot that waters every field without flooding a village, so there is always a way.

Code and text written with AI assistance; checked by PN Scripts with automated tests. The island is drawn and the sound synthesised by code.
