This is a brilliant twist on an old favourite, 3D X-O (3 Dimensional Noughts and Crosses) challenges even the smartest of us.
How to play: First choose who will be X or O. The player with 14 pieces goes first and puts one piece on any rod. Players take turns, trying to create a line of 3 Xs or Os. The winner is the 1st player who manages to place 3 of their playing pieces in a horizontal, vertical or diagonal line.
Alternatively: With younger children, they may 'struggle' with the 3D concept and keep trying to play like a flat old 2Dimensional version. Overcome this by suggesting they play until the game board is full and all 27 pieces have been placed - the player with the most lines of 3 wins.
