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. From Everspring, the makers of Everspring: Immortal Defense.

Verdict
The clearest difference is in-app purchases: Rill at none against FORMBO's 1. Rill also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.0). FORMBO's advantage is update cadence (daily vs every 4 days). On price and ads there is nothing between them.
