noun
pachinko winnings; balls won in pachinko
Refers specifically to the balls won as prizes in pachinko, distinct from the balls purchased to play.
See also: パチンコ
今日は出玉が多くて、景品と交換できた。
Today I won a lot of pachinko balls and was able to exchange them for prizes.
パチンコ is the game itself; 出玉 refers to the balls won while playing.
Compound of 出 (de, 'coming out') and 玉 (dama, 'ball'), literally 'balls that come out'. The spelling 出球 uses the character for 'ball' (球) more directly.
