## What is Jo?

Rock, paper, scissors with your brain.

Drop a piece and it flips every neighbor it beats: rock crushes scissors, scissors cut paper, paper covers rock. Every flipped piece flips its own neighbors, and the chain keeps spreading. Leave one type on the board to clear the level.

The rules fit in one sentence. The puzzles don't: where you drop, what you drop and in what order decides everything.

• Chain reactions: one good drop can flip half the board.
• Three stars for solving in par, the fewest drops possible, proven by a solver.
• Hundreds of levels: the basics, then anchors, walls, shields, portals, limited pieces, and everything at once.
• A new daily board at midnight: one big 9×9 puzzle, the same for everyone, with the day's twist.
• Hints when you're stuck. Earn more by solving the daily and by finishing a chapter with three stars.
• Two looks: Minimal, clean and editorial, or Classic, with real rock, paper and scissors. Light or dark.
• Sound that rises with every wave of the chain, and a tick you feel on each one.
• Achievements and leaderboards in Game Center.
• Colorblind mode. Made for iPhone and iPad.

Free to start, with a new daily board every day. One purchase, "Unlock all levels", opens every chapter and every level added later, shared with your family. No ads, no subscription, no account, no tracking.
