Pay for game that provides a walkover? (10)
I believe the answer is:
footbridge
'that provides a walkover?' is the definition.
(a footbridge lets you walk over a river)
'pay for game' is the wordplay.
'pay for' becomes 'foot' (as in to foot the bill).
'game' becomes 'bridge' (card game).
'foot'+'bridge'='FOOTBRIDGE'
(Other definitions for footbridge that I've seen before include "walkway" , "unsuitable for the motorist?" , "Over which one may walk" , "Pedestrian crossing, as it were" .)
