## What is Bird Post?

Let a little bird deliver your colorful letters.

Bird Post is a calm sorting puzzle where luck and speed play no part — all you do is think about the order.

HOW TO PLAY
- Tap a letter, and a little bird carries it to the mailbox of the same color
- If the colors don't match, the bird waits on the perch for a while
- Deliver every letter before the perch fills up to clear the level

WHY YOU'LL LOVE IT
- 300 handcrafted levels, every single one verified to be solvable
- The full order of upcoming mailboxes is always visible — zero luck involved
- Made a mistake? No problem. Undo as many times as you like
- No lives, no time limits, and nothing to buy
- Take on "Today's Delivery", a fresh daily challenge, and build your streak
- Works completely offline — play anywhere, even without a signal
- Supports Dark Mode, VoiceOver, and larger text sizes

A QUIET KIND OF PUZZLE
There are no flashing lights or loud fanfares here. Bird Post is designed to feel like tidying a small desk: pick up a letter, find where it belongs, and enjoy the gentle satisfaction of a job well done. Because the entire mailbox queue is visible from the start, every level is a pure logic puzzle — when you get stuck, a few undos will always get you back on track.

Collect commemorative stamps as you progress through the chapters, keep your daily streak alive, and switch on Color Assist Mode if you would like shape markers shown on top of colors.
