A puzzle bug is actionable when someone else can replay the same state. Name the game under Puzzle Games, level or daily seed, difficulty, and platform.
Record the board before the move, the exact input, expected rule, and actual result. If the puzzle is randomized, include the seed or a save code; if unavailable, attach a screenshot before and after. Test undo, hint, reset, and reload separately. For touch problems, note screen size and whether the page was zoomed. Avoid posting a live daily solution in a title.
A claim such as “this puzzle is impossible” needs either a reproducible layout or a rule contradiction. Separate a genuine invalid state from a difficult but valid puzzle. Text steps help both developers and players inspect the evidence.
