## Description

Behind Junction Nine is a published mathematical result: in a 3×3 grid where any rectangle can be spun 180 degrees, every arrangement can be returned to order - and never in more than nine spins.<br><br>We designed the puzzles and independently calculated the fewest spins each one takes. See if you can match the minimum.<br><br>HOW IT WORKS<br>Spin any rectangular section of the grid 180°. Remember - squares count as rectangles. A move can shift several pieces at once, so fixing one connection can disrupt another.<br><br>Rotate tiles until every connection lines up. Then keep going: can you match the fewest possible spins?<br><br>Every puzzle has a proven minimum.<br><br>ORIGIN — FREE<br>Start with Origin, a collection that introduces the mechanic and builds from simple puzzles to genuinely tricky ones.<br><br>TRANSFER<br>Unlock a second collection with a new set of puzzles to master.<br><br>DESIGNED FOR THINKING<br>- No ads<br>- No timers or penalties<br>- Optional haptic feedback and sound<br>- Light and dark themes<br>- More puzzle packs planned<br><br>Quick to learn. Surprisingly hard to perfect.
