sobosuba is a soft-body merge puzzle: aim numbered blobs into a stack and combine matching values. The developer describes soft shots for careful placement and hard shots for pushing pieces into gaps on sobosuba.com. The Steam description also says there is no explicit time pressure. This guide summarizes public sources rather than claiming a personal play session.

The full game is $3.99 on Steam (US price checked 2026-10-29) for Windows and Linux. macOS is not listed. iPhone and Android are “coming soon,” with a free try and a one-time unlock, in the site’s own words. The browser build is the free demo, not the full game.

Steam showed 365 reviews and 97% positive on 2026-10-29. The public patch notes stop at 1.2.3 (2026-09-08). A beta branch, 1.3.3, is named in the developer beta thread opened 2026-10-26 and edited 2026-10-27.
