Brilliant twist on old favourite, 3D XO 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, play until the game board is full and all 27 pieces have been placed – the player with more lines of 3 wins.
