Monster Mailroom

The monsters need their mail. You bring the brains.

Monster Mailroom is a colorful sorting puzzle where every tap matters. Choose enchanted cargo from a nine-slot board and build matching pairs or triples before your dispatch tray fills. The first shifts teach one idea at a time; later routes combine frozen labels, fragile parcels, mimics, portals, wild prisms, power cargo, and district-specific rules into satisfyingly clever decisions.

MASTER 150 HANDCRAFTED SHIFTS Travel from Sunrise Depot to the Royal Mailroom through 15 illustrated districts. Earn up to three stars on every shift, replay unlocked routes, and find the cleanest solution across a campaign that grows from welcoming tutorials to multi-wave expert challenges.

DISCOVER 64 MAGICAL CURIOS Sort creature keepsakes, living plants, rare materials, arcane potions, and ancient relics. New districts introduce stranger cargo, fresh silhouettes, and new rules to master.

CHOOSE A COURIER. CHANGE YOUR STRATEGY. Eight full-art monster couriers bring meaningful perks. Milo rewards clean streaks, Luna scans for fewer coins, Bramble packs fragile cargo efficiently, and Pippa, Atlas, Nimbus, Cinder, and Tink unlock power, wildcard, reroll, express, and rewind strategies.

MAKE EVERY ROUTE COUNT Clear smart sets to build combos, protect limited tray space, complete district objectives, collect quest rewards, and fill your Cargo Codex. Use earned coins on Undo, Scanner, and Board Reroll only when a route needs help.

FAIR HEARTS AND OPTIONAL REWARDS The first ten training shifts have free retries. After that, failed routes use one of five hearts, with one returning free every 30 minutes. Rewarded videos are always optional: choose one for a rescue, heart, small coin reward, or completed-shift bonus. Frequency-capped ads can appear only at natural breaks, never during a puzzle, and Premium removes them.
