## What is Rivulet?

A calm new pipe puzzle, every single day.
No ads. No time limits. No energy bars. Just you, a beautiful 3D lattice, and the quiet satisfaction of making the flow connect.

Rivulet is a premium daily logic puzzle: rotate elegant pipe pieces in a soft, blueprint-inspired 3D world to route the source into its sink. Solve today's puzzle, keep your streak alive, and unwind for a few minutes that actually feel good.

Designed as a daily ritual — like your morning coffee, but for your mind.

A DAILY RITUAL, NOT A GRIND
A fresh puzzle arrives each day — carefully tuned to a weekly difficulty rhythm — plus a tougher weekly challenge. Solve it in a few unhurried minutes, then come back tomorrow.

WHY RIVULET
- One fresh puzzle every day, plus a harder weekly challenge
- Daily Mini: a second, easier daily for a gentle start
- Beautifully minimal 3D, tactile and satisfying to rotate
- Zero pressure: no ads, no time limits, no loot boxes, no nagging
- Build streaks, earn stars, climb the ranks
- 28 achievements to chase at your own pace
- Game Center leaderboards if you like to compete
- Free Play: unlimited practice in easy, medium, or hard
- Stuck? X-ray shows the solved network as a 2-second ghost (first 6 free)
- Today and the last 3 days always free; unlock the full archive with Pro
- Progress and streaks sync across your devices with iCloud
- English and Turkish, fully localized

PREMIUM AND HONEST
Rivulet is premium by design. The core game is yours with no interruptions, ever. One small one-time Rivulet Pro unlock and a few optional cosmetic theme packs are the only purchases, and they are completely optional. We never sell your attention.

A QUIET DAILY HABIT
A couple of minutes a day. A clear mind. A growing streak. That is the whole idea: a small, beautiful moment of focus you will look forward to.

No internet required. Plays fully offline. iPhone and iPad.

Connect the flow. Find your calm.
Start today's puzzle now.
