When you create a game, you get a UUID (the game's id). Use this URL (hansa-teutonica.com/games/<game-uuid>) to get the invite links for each player. If you forget the game's ID, it's lost - create a new one.
Each player gets a unique link to the game hansa-teutonica.com/play/<player-uuid>.
A game is directly created from the React frontend. You get a redirect to the game details page, and you can share links to other players.
Other players load the game via their unique player link.
Their moves overwrite the game state, so they can fuck up (or hack) the game for everyone.
