Every player in PUZRU solves the same puzzle, but nobody can type into somebody else's board. That separation is deliberate: the puzzle is shared; the work is private. Only a completed solution is submitted for verification.
How the first solver is decided
When valid solutions arrive, the global authority processes them in one authoritative order. The first accepted valid claim while the puzzle is OPEN becomes the single Discoverer. The world immediately becomes SEALED and other valid solutions accepted before the shared deadline are recorded as verified solvers.
Why this architecture feels fair
Partial moves are never broadcast, so another player cannot copy your progress or overwrite it. The winning event is a verified completed board rather than an optimistic client-side button press.
One transition for everybody
After the contribution window closes, PUZRU shows a shared 20-second transition with the completed board and the six values that will survive into the next Chain Puzzle.
Put the idea into practice
The fastest way to understand the interaction between row, column and cage constraints is to solve a board. Start in the 200-puzzle progressive Training Room, then enter the live world whenever you are ready to race for Discoverer.
