Entertainment on board could be playing cards with matches (4,5)

Ross

I believe the answer is:

deck games

'entertainment on board' is the definition.
(games or entertainments on a ship)

'playing cards with matches' is the wordplay.
'playing cards' becomes 'deck'.
'with' says to put letters next to each other.
'matches' becomes 'games' (as in sports matches).
'deck'+'games'='DECK GAMES'

'could be' is the link.

I've seen this clue in The Telegraph.
