Create the room right away — players can scan in and hang out in the lobby while you pick the pack below. The display simply re-themes when you choose.
Each finished game auto-downloads an updated file. Re-upload it here before the next game and new results append to keep ongoing player & team scoring.
Everyone stays in the room. Pick another pack and start again — new players can still join with the same code.
The big screen is showing the “Thanks for Playing” fireworks. When you're ready, end the show to send everyone back to the home page.
