## What is Tubulus?

Tubulus is a pipe rotation puzzle game that's easy to learn and hard to put down.

Every pipe on the grid needs to be rotated into the right position to connect the source to the drain. One tap rotates a pipe. When the flow connects, you'll know.

WHAT'S INSIDE

90 hand-crafted levels across Easy, Medium and Hard — grids get bigger, pipes get more complex, and T-junctions and crossings add a whole new layer of challenge.

DAILY PUZZLE

A brand new puzzle every single day. Same puzzle for everyone worldwide — can you complete it with fewer moves than your friends?

TIMED MODE

Race the clock for bonus coins. Every difficulty has a time limit — beat it and earn extra rewards.

HINTS

Stuck on a pipe? Spend coins to fix one at a time, or reveal the full solution for a few seconds to get your bearings.

COINS

Earn coins by completing levels and daily puzzles. Claim your daily bonus. Spend coins on hints when you need them.

No energy system. Just puzzles.
