Two card games one may come across (7,6)
I believe the answer is:
pontoon bridge
'one may come across' is the definition.
I can't tell whether this defines the answer.
'two card games' is the wordplay.
'two card games' can mean two replacements for 'card game'.
'card game' becomes 'pontoon' (pontoon is a card game).
'card game' becomes 'bridge' (bridge is a kind of card game).
'pontoon'+'bridge'='PONTOON-BRIDGE'
Can you help me to learn more?
(Other definitions for pontoon bridge that I've seen before include "channel crossing" , "Floating structure for crossing water" , "A large float passing between banks" , "River crossing on floating supports" , "Makeshift way to get over current" .)
