  • オセロで(あそ)ぶ: to play Othello
  • オセロが(つよ)い: to be good at Othello

CULTURAL NOTE:
The name comes from Shakespeare's "Othello" — the contrast between (くろ) (black) and (しろ) (white) discs mirrors the play's themes. The game is popular as a family activity and commonly found in game collections alongside 将棋(しょうぎ) and 囲碁(いご).
