Q: Where should I go after learning the controls?

Start with stacking tips , then try an achievement challenge or improve your own high score.

The merge

Two blobs with the same number merge into a larger one. Their soft shapes can squeeze between nearby pieces, so position and shot strength both matter.

Controls

Press and drag to aim a shot.
Adjust the direction and strength before releasing.
Release to launch the blob.
With a mouse, right-click to cancel an aim.

Try gentle shots when placing a blob beside a match. Use a stronger shot when you want to push another piece. On a phone, see the small-screen guide.

How a run ends

Watch the two switches near the top of the arena. Pressing both at once ends the run. Leave room above the pile when planning a shot.

Small matching values arranged along the bottom of the arena.

Large blobs leave less room for another shot.

Try one move at a time

Look for a reachable match near the surface. Make a gentle shot and watch how the pile settles before aiming again. If the match is buried, consider how moving a nearby piece will change the stack.
