About
Rill is a daily logic puzzle you can learn in thirty seconds and play for years.
THE RULE
Draw one channel of water through every plot of the field, starting at well 1 and passing the numbered wells in order. Fences block the way. The crops green up behind your line. That's it — no reading, no timers you didn't ask for, no lives.
THREE WAYS TO PLAY
• DAILY — one field a day, identical for everyone in the world. Water it, then share a spoiler-free grid that shows where your channel went wrong (or didn't). Streaks count consecutive days.
• LADDER — endless levels that grow from 4×4 to 8×7. Every level is the same for every player, so times are comparable. Ranks from Trickle to Ocean; new seasons of the field unlock as you climb.
• BLITZ — 90 seconds, as many fields as you can. Every solve adds time. One more round is always a good idea.
MADE FOR YOUR THUMB — AND YOUR iPAD
• Drag to draw, drag back to erase. Fast swipes and diagonal jumps are understood.
• One practice field teaches the rules; the rest you learn the moment you bump into them.
• Hints that rewind you to where the channel went wrong, instead of giving away the answer.
• Your puzzle in progress is saved. Come back any time.
• Optional daily reminder, and a nudge on the evening your streak is at stake.
• iPhone and iPad, portrait or landscape on iPad. Day, night, harvest and paddy themes, sound that rises as your channel grows, haptics on every plot.
HONEST BY DESIGN
• No account. No sign-in. Nothing to buy.
• Free, supported by ads: no ads at all during your first puzzles, a small banner below the field after that, and full-screen ads only between levels — never in the middle of a puzzle, never between finishing the daily and sharing it.
• Every puzzle is generated on your device with exactly one solution.
