The Game at a Glance
What is sobosuba?
sobosuba is an indie merge puzzle game developed and published by keepeetron for Windows and Linux on Steam. The game swaps rigid grid layouts for elastic soft-body physics, featuring numbered blobs called Sobos that stretch, compress, and deform like water balloons.
During a run, you aim and launch Sobos into a container to combine matching values and chase high scores. The round continues without time limits until the stack rises and depresses both upper boundary bumpers, bringing the session to an end.

From your first launch to high scores and achievement challenges, choose the topic you need.
Beginner Guide
Learn how to launch squishy blobs onto the stack and merge them into bigger blobs. Use gentle launches for careful placement and stronger launches to push blobs through tight gaps, with mouse and gamepad controls for aiming, dropping, and cancelling shots.
Drag with a mouse or point your gamepad stick to fire, or drop a Sobo straight down at zero force.
Isolate high numbers to one side to prevent massive blobs from burying smaller low-tier values.
Keep blobs below the top sensors to avoid compressing both bumpers and ending the run.
Achievements and Color Unlocks
Explore all 30 Steam achievements, including uninterrupted merge chains, airborne merges, float-bar milestones, and exact-score challenges. Every achievement unlocks a color style, giving you new visual rewards as you complete different objectives.
Combine two identical blobs midair so the result touches nothing for a quarter second.
Leave a single target blob isolated in the stack without any other pieces below the float bar.
Trigger an intentional game over when eligible blobs equal target totals like 0, 10, 100, or 1000.
More details
Every completed achievement grants an alternate visual color style to use on future runs.
High Score Tips
Choose launch strength to balance precise placement with forceful pushes, and account for sideways momentum when launching a Sobo from the float bar. Chase higher scores on the online leaderboard and compare your progress with friends through live score displays and the friends filter.
Fresh blobs appear faded and only add their points to your scoreboard after completing a merge.
Matching numbers that touch along the upper float bar can merge before you fire them.
Use gentle drops for neat stacking and high-speed shots to squeeze through tight crevices.
Free Demo and Platforms
Try the free Steam demo before buying the full game for Windows or Linux. The official website also links to a browser demo on itch.io and identifies mobile development as a planned release.
The free demo is playable as a downloadable client on Steam and in web browsers on itch.io.
Demo runs end faster because upper fail bumpers sit lower than in the commercial game.
Achievements, cosmetic color style unlocks, and Steam leaderboards are disabled in the demo.
System Requirements
Check the published PC requirements, including 2 GB RAM, 200 MB of storage, and the listed processor and graphics specifications. The developer describes these minimum requirements as untested estimates and notes that weaker processors and integrated graphics may also run the game.
Requires 64-bit Windows 10 or Linux alongside 2 GB of RAM.
Runs on an AMD Ryzen 5 1600 or Intel Core i5-10400, including weaker CPUs.
Lists an NVIDIA GeForce GTX 1050 and requires 200 MB of available disk space.
Save and Resume Guide
Pause a run between sessions with the save-and-resume feature introduced in version 1.2.3. Closing the game saves your session automatically, and the main menu also provides a Save and Quit option so you can continue after reopening.
Open the in-game main menu and choose Save and Quit to store your board state.
Clicking the window close button automatically triggers an auto-save upon exiting.
Relaunch the game to resume your board state without checkpoint rewinds or undo options.
