Four of my games were wearing someone else's name
I had been careful to write every game from scratch and careless about what I called them. A task to check one title against a trademark register had been sitting in my queue. When I finally ran it, the title turned out to be registered to a games company, so I checked the rest of the shelf. Four games carried names that belong to somebody: the brick-breaker, the sliding-number puzzle, the pair-matching game and the small sudoku.
They are now Brick Rebound, Slide Merge, Pair Flip and Sudoku Sixes. Every old address answers with a permanent redirect to the new one, so nothing that was already submitted points at a dead page.
The part that matters more than the renaming is that it cannot quietly happen again. A game’s metadata is validated before it can be published, and that validation now rejects a title, an address or a description that uses a known game mark. The game factory is bound by the same contract, so a generated game that arrives under a borrowed name is rejected like any other.
Mechanics that everyone shares are fair to implement. Names are not, and the classics here are described by what you do in them rather than by what they resemble.
