## What is Flue?

Flue is a pipe-connecting puzzle: link every pair of colors and fill the whole board without crossing a single line. Easy to learn, impossible to put down.

GAME MODES
• Zen — play at your own pace, no pressure, difficulty grows naturally.
• Time Attack — beat the clock and manage your lives carefully.
• Daily Challenge — a brand new puzzle every day, with streaks and weekly bonuses.
• Insane — the ultimate test: walls, bridges and portals combined, star-rated by each level's real solving difficulty.

FOUR DIFFICULTY TIERS
From Easy to Expert, hundreds of boards individually calibrated so the challenge actually grows — not just bigger grids, but genuinely harder puzzles.

Earn coins by solving levels and spend them on hints, auto-solve or skipping a level when you need to. No pressure, no forced ads.
