## What is Postmark Protocol?

Stamp the instructions. Send the route.

Every letter on your desk needs a plan before it can find its way home. In Postmark Protocol, you build that plan by placing instruction stamps along a printed route, then press Dispatch and watch it play out exactly as written.

When something goes wrong, the route shows you why. Move a stamp, try again, and get a little closer each time until the letter reaches its destination.

BUILD THE ROUTE
Choose from seven commands, Turn Left, Turn Right, Wait, Reverse, Fast, Slow, and Jump, and place them on marked spaces. Timing and direction both matter, and you will feel the difference the first time you get one wrong.

LEARN THREE KINDS OF INK
Standard ink fires once per visit. Double ink fires twice. Permanent ink locks a stamp in place until you reset the sheet, so plan carefully before you commit.

HANDLE SPECIAL DELIVERIES
Fragile parcels cannot take a bump. Express Mail will not wait around. Registered Mail needs a checkpoint visit at every stop. Later routes mix these rules with timed gates, return paths, and moves measured down to the cycle.

WORK THROUGH 36 HANDCRAFTED DELIVERIES
Six chapters carry you from the easygoing Local Route to the tense final Night Shift, each one teaching a new idea before folding it into everything you already know.

EARN YOUR POSTAL SEALS
Deliver the letter and earn Delivered. Do it efficiently and earn Efficient. Find the shortest route that still qualifies and earn Perfect Route. Every result and every delivery you unlock is saved right on your device.

BUILT FOR UNHURRIED PLAY
A short guided first delivery gets you started, and the handbook is there whenever you need a reminder. Music, sound effects, and haptics are all yours to adjust.

No account, no ads, no in-app purchases, no subscriptions, and no downloaded content. Everything plays offline, the same on iPhone and iPad, in landscape.
