Atomixa: Merge Elements

Atomixa is an element-themed merge puzzle. Start with hydrogen, swipe the board, and combine identical elements into the next atomic number. Progress through goal-based levels with move limits and star ratings. Discover elements, explore the periodic table, and try special boards with catalysts and experiment bottles. Features: - Mainline levels, endless play, and daily challenges. - A next-element preview to help plan your moves. - Undo history that survives closing the app. - Retry the Same Experiment to explore another solution from the same starting board. - An element collection, achievements, daily supplies, and gameplay statistics. - Optional Game Center leaderboards for endless scores, highest elements, and your best daily-challenge score. - Sound, haptic, particle, and reduced-motion settings. Core gameplay works offline and does not require an app account. Game Center is optional and requires an Apple sign-in and network access. The daily-challenge leaderboard keeps your best score across completed challenges; it does not reset each day. Remove Ads is an optional one-time purchase that removes banner and interstitial ads. Rewarded ads remain optional.
