You are using brackets, and that is a method call. You need square brackets

games[gets.chomp]

but also, arrays are indexed by integers, so you would need to convert
the user's input:

games[gets.to_i] # to_i removes non number characters like \n already
and will default to 0 if it can read a number from the string

Hope this helps,
