'and growing particularly in south africa' is the definition.
I can't judge whether this defines the answer.

'very popular game at school' is the wordplay.
'very popular' becomes 'redhot' (I've seen this before).
'game' becomes 'poker' (poker is a kind of game**).
'at' is a charade indicator (letters next to each other).
'school' becomes 's'.
'redhot'+'poker'+'s'='RED-HOT POKERS'
