Game that shows self-restraint (8)
I believe the answer is:
patience
This clue could be a double definition.
'game that shows self' is the first definition.
'patience' can be an answer for 'game' (patience is a kind of game). I'm unsure of the rest of the definition.
'restraint' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for patience that I've seen before include "Card game played by one person" , "Card game for one player" , "Game, tolerance of delay" , "there's no one else to play this game" , "Calm endurance as in card game for one" .)
