Read full descriptionHide full description
One parcel. One wheel. One door at the end of the street. Undelivered is a balance game about getting a parcel there in one piece. Your courier rides a single wheel with the box on top, and every tap moves the wheel. Tap the side the parcel is tipping toward to catch it. Lean forward to pick up speed, let it tip back to slow down, and try to stop right on the doorstep. It feels tricky at first. Then it clicks, and you start reading the street a few steps ahead. What you'll find: • 75 handmade deliveries across five worlds: city streets, the Moon, a storm, the deep sea and a sorting depot • Seven kinds of parcel, each with its own quirks: heavy, liquid, fragile and more • Ferries, lifts, trams, wind, water and plenty of other things in your way • Short runs and instant retries, so a fall never costs you much • Optional stamps for careful, quick and clean deliveries Undelivered plays fully offline and doesn't need an account. The whole game is free. Banner ads appear in the menus and on the delivery receipt, never while you're playing. The one-time Supporter Pack removes them and helps keep the game going.

Verdict
The clearest difference is ads: Sisyphos at none against Undelivered's shown. Sisyphos also leads on iOS requirement (12.0 vs 26.0). Undelivered's advantage is update cadence (every 6 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
