How Cadra works
- Cadra focuses on one readable core action: plant seeds so the board grows into the target.
- It is about constraints: read the board, make one clean deduction, then let the next deduction appear.
- A new Cadra 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
Cadra 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.
