Game is fixed, making it hard for the elderly (6)
I believe the answer is:
ageism
'it hard for the elderly' is the definition.
The definition suggests a singular noun which matches the answer.
'game is fixed' is the wordplay.
'fixed' indicates anagramming the letters.
'game'+'is'='gameis'
'gameis' is an anagram of 'AGEISM'.
'making' acts as a link.
Can you help me to learn more?
(Other definitions for ageism that I've seen before include "Prejudice on grounds of advanced years" , "Non-PC attitude to senior citizens" , "Prejudice based on advanced years" , "Unfair treatment" , "Form of discrimination" .)
