New puzzle every day
Connect today’s path
Start on any cell of the 5×5 number grid and connect a path through adjacent cells (up, down, left, right) without reusing a cell. Make the digits on your path add up to exactly the target. The winning path links 4 to 8 cells — and every day has exactly one solution. Pure logic, zero luck — and the same puzzle for everyone on the planet today.

Sudoku is a beloved number puzzle, but it is a long fill with fixed rules. A daily number-path puzzle keeps the pure-logic feel in a shorter, connected, target-driven format.
Read →Frequently asked questions
- Is it free?
- Yes — completely free and unlimited. No signup, no payment to play the daily puzzle. Everything runs locally in your browser.
- How is the daily puzzle chosen?
- A deterministic algorithm builds the grid and target from the UTC date, so everyone in the world gets the exact same puzzle each day. It is never produced by an AI model, and no puzzle is ever sent from a server.
- Is my progress uploaded anywhere?
- No. Your streak and stats are stored only in your browser (localStorage). Nothing about your play is sent to a server or stored in any database.
- How is this different from Sudoku?
- NumberFlow is a path-sum puzzle: you connect one route through adjacent cells to hit a target total, not fill a 9×9 grid. It is an independent puzzle, not affiliated with Sudoku or any other number-game brand.
