About this game

Nodal Puzzles — Five calm, handcrafted logic puzzles. One cozy collection.

No accounts. No timers forcing you. No internet required. Every puzzle is generated on-device, uniquely solvable, and rated by the same human deduction that powers your hints — so you're never asked to guess.

Meet the crew and pick your puzzle:

👑 Corgi Crowns — with Clive the Corgi
One corgi per row, column & colour region. No two touch — not even diagonally. Dots mean “no corgi here.” The classic star-battle logic, now 100% corgi.

🐜 Ant Trails — with Dot the Ant
Help Dot get home. Draw one continuous trail that visits every cell exactly once, hits the numbered checkpoints in order (1 → 2 → 3 …), and never crosses a wall. The Hamiltonian path puzzle, made tactile.

✨ Constellation — with Sparky the Firefly
A night sky, two fireflies per row, column & region. Fireflies never touch, even diagonally. Place dots to eliminate, stars to shine — then watch the constellations connect.

🦎 Kami's Shades — with Kami the Chameleon
Kami paints the wall in rectangles. Every patch holds exactly one clue number = its size. Drag from the clue to paint the rectangle. Tall, Wide, Square or Mystery — number + icon lock the shape. Cover every tile, no gaps, no overlaps.

🐧 Island Hoppers — with Pip the Puffin, Postmaster
Pip hops islands to deliver supplies. An island's number = how many bridges leave it. Tap an island and drag to the next — tap the bridge again to double it. Connect them all, no bridges crossing. The beloved Bridges logic, now an archipelago.
