FuseCells is a fresh grid logic puzzle built around one simple rule: every number tells you how many neighboring cells must share the same symbol. No ads. No guessing. Just pure logic. Inspired by the deduction of Sudoku, the neighbor logic of Minesweeper, and the pattern reasoning of Nonogram, FuseCells creates an original and satisfying cosmic puzzle experience. HOW TO PLAY Fill every cell with a cosmic symbol: Planet, Star, or Moon. Each number clue shows how many neighboring cells must contain the same symbol. Some puzzles use 4-way neighbors, while others include all 8 surrounding directions. Color-coded feedback keeps everything clear: • Green means correct • Yellow means still possible • Red means impossible Follow the clues, eliminate impossible choices, and reveal the solution using logic alone. YOUR COSMIC JOURNEY Travel through one continuous roadmap filled with carefully curated puzzles. • 3×3, 4×4, and 5×5 grids • 4-way and 8-way logic • Gradually evolving difficulty • Quick levels between harder challenges • Milestone summaries every 10 levels • Crystal ratings for efficient solutions • Personal best times and progress tracking The journey introduces new ideas naturally while keeping the rules simple and easy to understand.

You are shown two or three examples. Something happens in each of them — the same thing, every time. Nobody tells you what. Then you are shown one more, unfinished, and a few ways it could end. Only one of them follows the rule. That is the whole game. No timer, no lives, no streaks, no penalty for being wrong. Just the quiet moment where you see it. ONE ANSWER. PROVED. The most common complaint about logic and pattern puzzles is the answer you could defend that was marked wrong. Here that cannot happen. Before a puzzle reaches you, it is tested against a catalogue of 556 rival rules. If any of them explains the same examples while pointing at a different answer, the puzzle is not shipped. A hard puzzle here is never a guess. 270 HANDMADE PUZZLES, TEN WORLDS CHANGE — things become other things POSITION — where something sits is the message COUNT — how many is the answer DIRECTION — orientation carries meaning INSIDE — what contains what MIRROR — reflection and symmetry SEQUENCE — order that keeps going RULES — everything at once EXCEPTION — a rule can leave something out BEFORE — new in 3.0: you are shown the result, and you work out what came before it A NEW RULE EVERY DAY One Daily Rule, the same for everyone, free forever. Put it on your Home Screen or Lock Screen with the widget, and share the puzzle with a friend — the picture shows the question, never the answer. ENDLESS Puzzles built on your own device and proved by the same code before you see them, for as long as you want them. A HINT THAT DOES NOT SOLVE IT Every puzzle has one hint. It tells you where to look, never what to think. Hints are free everywhere. NOTHING TO INTERRUPT YOU No ads. No account. No sign-in. No notifications. No timer, no score, no leaderboard, no streak to protect. Nothing is collected about you, and there is no server to collect it. Works offline. iPhone and iPad. In English, Deutsch, Français, Español, Português, Italiano, 日本語, 한국어, 简体中文 and Türkçe. WHAT IS FREE, AND WHAT IS NOT Free: the first three worlds — 60 puzzles — the Daily Rule every day, and every hint. One payment, once, opens the rest: the remaining seven worlds and their 210 puzzles, Endless, the archive of every rule you have discovered, and the full statistics. No subscription. Nothing else to buy.

Verdict
The clearest difference is in-app purchases: RULE at none against FuseCells's 4. FuseCells's advantage is update cadence (every 6 days vs monthly) and iOS requirement (15.6 vs 17.0). On price, ads and device support there is nothing between them.
