Nucleo Merge

Build a tiny universe, one clever move at a time. Nucleo Merge is a cosmic puzzle game about fusing element cores and sorting your discoveries into matching targets. Drag twins together to create a higher core, plan your next move, and find the balance that clears each board. EXPLORE FOUR WORLDS Discover 120 handcrafted puzzles across four worlds. Each chapter brings a new way to think about fusion, from your first element cores to Crystal catalysts, Eclipse fractures, and Polar phase changes. MAKE EVERY MOVE COUNT Choose what to fuse and what to save. Fill targets in the right order, make room for reserve cores, and avoid combinations that leave the board unsolvable. DISCOVER NEW RULES Catalysts can fuse with different cores. Fractures split higher cores in two. Solar and Lunar phases change which fusions are possible. CHASE THREE STARS Earn a star for completing a puzzle, another for beating its time target, and a third for finishing without a mistake. Replay levels to improve your result. A LITTLE COSMIC ATMOSPHERE Glowing cores, fusion animations, world music, and sound effects accompany each puzzle. Toggle audio whenever you prefer quiet play. Fuse the cores. Find the balance.
