Nodal: how to play, rules, strategy and design notes
Turn links on until every node has its exact target degree. Here is how Nodal works, what makes the daily puzzle fair, and why it belongs in Wittora's collection of quick thinking games.
Nodal reduces graph theory to a friendly toy: every node simply wants its exact number of links.
How Nodal works
- Nodal reduces graph theory to a friendly toy: every node simply wants its exact number of links.
- It is about constraints: read the board, make one clean deduction, then let the next deduction appear.
- A new Nodal puzzle appears every day, and Infinite mode lets you keep practicing the same idea after the daily round.
Rules
- Start from the visible board or clue set and make a move that follows the core logic puzzle logic.
- Use the feedback on the screen to narrow the remaining possibilities.
- Win by completing the board, answer, order or hidden target. In Daily mode your result is recorded once; in Infinite mode you can keep experimenting.
Data and puzzle logic
Puzzles are generated ahead of time and audited by solver code so the live page can stay fast, static and cheap to run.
Lore and naming
Nodal is named like a small artifact from the Wittora shelf: compact, memorable and a little mysterious. The lore is intentionally light. The game should feel like a clever object you pick up for a few minutes, solve, share and put back glowing.
Where the idea comes from
The roots are classic pencil puzzles: grids, maps, loops, networks and deduction problems made friendlier for touch screens.
