RULE vs Calm Arrows

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.

Calm Arrows is a quiet puzzle you can play with one finger. Tap an arrow and it slides off the board in the direction it points. If something is in the way, it stays. Work out the order and clear the board. • No ads. No tracking. No account. • No timers, lives, or energy. A wrong tap only costs a star. • 200 levels that grow step by step: bigger boards, stones that block the way, frozen arrows that thaw as others leave, and locked arrows that wait for their key. New boards keep coming after that. • Soft wooden sound effects and calm piano music, each with its own switch. • One daily puzzle, the same for everyone in the world. • Works offline. • Free. An optional tip in Settings supports the developer and unlocks nothing.
