sobosuba play guide

Launch soft blobs and build bigger merges.

sobosuba is a physics merge puzzle where you shoot squishy numbered blobs into a container. Bring matching numbers together, make larger blobs, and work toward a higher score. The shape of the pile matters as much as the numbers on it.

A gentle launch can place a blob beside its match without upsetting the stack. A powerful shot can push other pieces aside and squeeze into a gap. Let the movement settle, notice what changed, and choose the next shot from the board you actually have.

Your goal: Build larger blobs and improve your score
What makes it different: Soft shapes compress, rebound and move the pieces around them
First practice: Try a soft and a strong shot toward the same area

Watch how the blobs deform, settle into gaps and change shape when they merge. Follow both the landing position and the force of each launch.

Five boards, five things to notice

Look for reachable matching numbers, open paths and the room a larger blob will need.

A 2048 blob and two 1024 blobs packed into the soft-body game container — **Keep a route open beside your large blobs.**A growing 2048 or 1024 takes up space that smaller pieces could once pass through. Look for a matching blob you can still reach from above.

The aiming arrow points down from a selected 32 blob — **Aim for the landing, not just the arrow.**The selected 32 has an aiming line, but the 128 and 64 below can change its path. Think about the first collision and where it might send the shot.

Small 1 and 2 blobs arranged alternately across the bottom — **Small pieces can separate useful matches.**Alternating 1 and 2 blobs leave matching numbers apart. Filling the bottom is less useful if it makes those pieces difficult to bring together later.

Large 2048 and 4096 blobs surrounded by smaller numbered blobs — **Big numbers make the remaining gaps valuable.**With a 2048 and a 4096 in the stack, decide which opening you want to preserve before dropping more pieces into it.

Three separate 1024 blobs with smaller blobs between them — **Find a way between separated large blobs.**Three 1024 blobs sit in different parts of this board. Clearing a small match between them and pushing a large piece are different tools; choose the change you want.

Choose the shot for the situation

Gentle placement and powerful launches compared
What you see	What to try	What to watch
A matching blob is exposed	Place a gentle shot beside it	Keep contact without scattering the stack
The match is behind other pieces	Use a deliberate, stronger launch	The path after the first collision
The stack is getting tall	Make accessible merges to open space	Do not plug the next entry point
A bigger merge is within reach	Plan where the new blob will settle	The next match and anything between them

Follow the order in which pieces move after a shot. The space left by a merge can be just as useful as the number it creates.

Questions before you play

Is the browser demo free?

Yes. The embedded browser demo is free. The full Steam game is a paid product purchased through Steam.

Is this a mobile game?

The author describes the browser demo as PC-oriented. Start with a computer and mouse. The Steam version supports Windows and Linux.

Does it use the same controls as 2048?

No. Instead of sliding a whole grid with arrow keys, you select a blob and launch it with a chosen direction and strength. Deformation and collisions affect the result.

What should I practice first?

Find a matching number and look at the pieces between it and your shot. Begin with gentle placement, then use a stronger launch when you have a specific piece to move.
