Write the word 'football'
Forgive this seemingly odd choice, it just appealed to my silly sense of humour.
A basic word game for children using common football phrases and words to fill in the gaps in written sentences about non football subjects. Everyone plays and then the person who uses the most correct words from the hidden list is the winner.
This old version uses words like 'ball', 'amateur', 'net', 'linesmen;, 'shoot', 'turnstile' etc
The modern version would use words like 'bite', 'feigning', 'simulation', 'over paid wasters', 'goal line technology', 'consortium' etc!
