Kanoodle-style logic puzzles have been a family favorite for years. It's satisfying, it's tricky, and once you're hooked, you want to solve just one more. Katachi-Go, our free browser version, brings that same colorful sphere-piece style online – but with a twist that changes how you actually solve it.
Virtual Clues
A new clue system that changes the gameplay. Katachi-Go randomly selects a single sphere from each piece as a virtual clue – making solving a whole 12-piece puzzle from scratch more reasonable. Every clue points toward one correct solution, so you're reasoning your way there, not guessing and checking. You'll know you're right before the last piece is down.
Hundreds of Puzzles, One After Another
A physical puzzle usually ships with one challenge book. Katachi-Go has thousands of puzzles across seven worlds, and the moment you solve one, the next is already waiting. There's no flipping back to "start over" or hunting for a fresh challenge; it's built for playing in quick succession, how many can you get through in one sitting?
Relaxing, Not Stressful
Good logic puzzles are supposed to feel calm: a quiet kind of thinking that clears your head instead of filling it with pressure. Katachi-Go keeps that spirit intact. There's no clock forcing your hand and no one waiting on you to finish before dinner. Play at your own pace, pick your own difficulty, and let your brain do what it likes best.
Shapes You Won't Find in a Traditional Set
Katachi-Go isn't a copy of a classic Kanoodle set; it uses its own original 12-piece design. Familiar rules, genuinely new puzzles to solve.
Nothing to Lose, Literally
Anyone who's played a physical version knows the real threat isn't the puzzle, it's the couch cushions, the car seat, and the box of loose pieces that's somehow always missing one. Katachi-Go has no booklet to misplace and no tiny pieces to vanish. Everything lives right here on hoffmakers.com, ready whenever you are.
Built for the Whole Family
Five difficulty modes, Easy through Extreme, mean the same game works for a five-year-old just learning to match shapes and a puzzle veteran chasing a personal best on the leaderboard. Everyone picks their own level, and everyone's still playing the same game together.
