This is a game for two players. You will need a 7x7 square grid and two colours of counters.
Players take turns at putting his/her counter on the lowest space in any column.
The first player to make a straight line of four counters wins.
The line of four can be across, up and down, or diagonal.
Does it matter who goes first?
Is it better to put counters in the middle columns or the outside columns? Why?
