109 .— Noughts and Crosses.

The solution is as follows:

Between two players who thoroughly understand the play every game should be drawn. Neither player could ever win except through the blundering of his opponent.

  • If Nought (the first player) takes the centre, Cross must take a corner, or Nought may beat him with certainty.
  • If Nought takes a corner on his first play, Cross must take the centre at once, or again be beaten with certainty.
  • If Nought leads with a side, both players must be very careful to prevent a loss, as there are numerous pitfalls.

But Nought may safely lead anything and secure a draw, and he can only win through Cross's blunders.
