You are on a road to disaster.
You have a list of dozens of game names, and you have already set up two global variables with names picked from that list, with the need for your code to increase with the number of games.
If your code increases as your data increases, you are doing it wrong.
You must learn to work with tables (two dimensional lists of lists) .
I recommend setting up two Google Sheets:
- Games, with game name in column A
- Scores, with these columns
- Game name (copied from the Games sheet),
- Player Name
- Score (Numeric)
- Date (Use Numeric type and Date format)
Having 4 columns gives you grist for the mill when you want to sort and select by thos 4 columns.
