About

ClusterSum

A little counting. A little logic. A very satisfying click when it all comes together. In ClusterSum, every number tells you how big its group should be. Three connected 3s. Four connected 4s. Five connected 5s. Fill the board so every cluster fits. Only up, down, left, and right count—diagonals stay separate. The rule is simple. Finding how the groups fit together is the puzzle. FIND YOUR NEXT LITTLE CHALLENGE • Journey: work through a growing series of puzzles, with larger boards and decorative blockers along the way. • Daily: come back for a fresh puzzle each day, or explore the recent Daily archive. • Play offline: settle into a puzzle wherever you are. MAKE EACH MOVE YOUR OWN • Tap to cycle numbers. On boards that fit the screen, drag up and down to choose a value. When a board scrolls, swipe to scroll and briefly hold a tile before dragging to edit. • Read clear feedback as your clusters grow, complete, or run into trouble. • Undo an edit—or undo a board reset—while you find your way. • Use a hint when you want a nudge. The first three hints in each puzzle are free; extra hints cost coins. CONTINUE ON IPHONE AND IPAD Enable optional iCloud sync in Settings to share Journey progress, saved puzzles, Daily history, themes, and coins between devices using the same iCloud account. No separate ClusterSum account is needed. The first device sets the starting shared coin balance; other devices add their progress without adding their old balances. Independent unfinished-board versions are retained. Puzzle play and free hints work offline. With sync enabled, spending coins requires an iCloud connection. Use Sync Now to check the latest status. Haptics remain specific to each device. A BOARD THAT FEELS LIKE YOU Choose from colorful themes, switch haptics on or off, and enjoy a quick playable introduction to the rules. VoiceOver tile controls and support for larger text and Reduce Motion make more ways to play. Save your progress, collect Daily rewards, and see how far a run of perfect Journey solves can take you. A perfect solve uses no hints. Your finished Journey board stays on screen until you are ready for the next puzzle; Daily navigation stays with the calendar and date arrows. ClusterSum is free to download for iPhone and iPad. Optional in-app coin purchases are available. Coins can be spent on extra hints and Journey streak protection.
