Deltia: how to play, rules, strategy and design notes
Order the numbers so each step matches the difference clues. Here is how Deltia works, what makes the daily puzzle fair, and why it belongs in Wittora's collection of quick thinking games.
Deltia makes differences visible: the path is solved when every jump lands on the exact clue.
How Deltia works
- Deltia makes differences visible: the path is solved when every jump lands on the exact clue.
- It turns arithmetic into a tiny strategy problem where the best move is often about structure, not raw calculation.
- A new Deltia 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 number 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
Number sets are produced deterministically from the daily seed and checked so targets are solvable and non-trivial.
Lore and naming
Deltia 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
It borrows from mental-math games, balance puzzles and recreational mathematics, then removes the classroom pressure.
