Oakland/East Bay Math Circle

1. Choose a number. Circle it. Cross out all of the
   numbers in the same row and same column as the
   number you chose.
2. Choose a number that is not circled or
   crossed-out. Circle it. Cross out all the numbers
   in the same row and the same column as the number
   you chose.
3. Continue the same process of circling and
   crossing out numbers until there is only one
   number left. Circle it.

Criss-Cross - 1st Day of Class

• An exciting game of skill and strategy! Add two
  to seven additional points anywhere inside the
  dotted triangle game board. Players alternate
  turns drawing a single straight line joining any
  two points, as long as the segment does not pass
  through any other points or segments already
  appearing on the game board. The winner is the
  last player able to make a legal move.
