Merge Cat
Drop adorable feline icons into a jar to combine identical breeds into larger, more majestic cats. Success requires managing the physical volume of the container to prevent the pile from reaching the upper limit.
About This Game
Merge Cat Evolution (Merge Cat) is a Volumetric Physics-Merge puzzle based on the Suika (Watermelon) mechanic. The technical core is "Circular Collider Stacking"—players drop cats of varying radii into a container. It emphasizes Managing Static Friction to prevent the "Fail-Line" trigger.
How to Play
Tap to release a cat icon into the jar. The gameplay is Evolutionary Synthesis: combine two identical breeds to spawn a larger, higher-tier cat. Interaction involves Physics-Pushing—using the weight of a new drop to force two "stuck" cats at the bottom to touch and merge.
Tips & Tricks
Winning the long game requires "Size-Stratification." Never drop a large cat in the center; it creates "Inaccessible Pockets" underneath. Instead, Pin the largest cat to the bottom corner. This forces the "Rolling Physics" to funnel smaller kittens toward each other in the remaining open space, creating a natural merge-cascade that keeps the top of the jar empty.
