SweetStack

Line up the falling jellies just right, merge matching flavors, and watch your stack climb higher as the pressure builds in SweetStack.

The whole game lives on a single mechanic: a jelly drops from a slider that zips back and forth across the top of the screen. You tap or click to release it onto the stack below. Land it on an identical jelly and they fuse into a bigger, wobblier version. Miss the match and the stack gets messier, with odd shapes piling up and threatening to topple everything. What got me hooked was the near-miss panic. One time I had a stack of three purple jellies teetering on the edge, and I dropped a fourth one just as the slider crossed the exact right pixel. The resulting merge chain cleared half the board and gave me a score spike that felt illegal. Moments like that are why SweetStack works. It's not as brainless as it looks. You're constantly weighing safe placement against risky merges, especially when the stack gets tall and the slider feels faster than it should. The sound effects are sticky-sweet, the jellies jiggle with satisfying weight, and every near-collapse makes you hold your breath.

Control bar is at the top which decides where next jelly should fall. Merge and get higherscore.

Aim for the center of identical jellies to trigger merges more reliably. Don't rush drops when the stack is low; use the full slider range to set up future combos. Watch the shadow under the falling jelly to predict its exact landing spot. If the stack leans one way, drop on the opposite side to balance it. Prioritize merging lower-level jellies first—they vanish and free up space. The slider speeds up as your score climbs, so keep your eyes mid-screen.
