Post Office: Tidy Up!

Post Office: Tidy Up! is a single-player, fully offline sorting simulator. An earthquake has emptied every rack in a 20 by 20 metre depot, leaving 3,360 parcels on the floor. The shift ends once every parcel has been put back in its place. The whole depot is accessible from the start, with nothing locked or gated.

Each parcel carries a printed label giving its courier, country, compartment and numbered slot. The depot has eight couriers, three countries and 24 posts, and each post holds 140 numbered slots. Parcel size determines the first choice: ordinary parcels go to the tall racks along the walls, while oversized ones go to the low islands in the middle. Parcels do not move by themselves and no rack is highlighted, so the player carries everything to its slot. A parcel placed correctly produces a short golden flash, and a completed compartment triggers a wave of light down the rack. Wrong guesses carry no penalty.

Shelved parcels earn points, which are spent on six upgrades: running, trolley, stack, pace, payload and arm span. A hand truck can move a whole stack of parcels in one trip. At the end of a shift, a report lists clean time, parcels shelved, compartments and racks finished, the share placed correctly on the first try, and metres walked. The game has Steam achievements, autosave so a shift can be resumed later, no timers, no in-game purchases, and support for 14 languages.
