The school-notebook game, no paper needed
Players take turns drawing a line between two neighbouring dots. Whoever draws the fourth side of a box claims it and must draw another line. When all lines are drawn, the player with the most boxes wins.
The trick is to avoid drawing the third side of a box, because that hands it to your opponent – and late in the game you’ll have to give something away. The hard computer counts how many boxes each move would give you and always sacrifices as few as possible. Choose a board from 3×3 for a quick game up to 6×6 for a long battle.
How to use
- Choose the board size and play the computer or a friend.
- Tap between two dots to draw a line.
- Complete a box to claim it – then it’s your turn again.
- When the board is full, the most boxes wins.
Ideas for using it
- Kids. easy level on 3×3 – a game takes two minutes.
- Long game. 6×6 against the hard computer needs real planning.
- Two players. pass the phone instead of tearing out a notebook page.
- Classroom. boys against girls on the whiteboard.
