I chose a game where you have a number of different boards full of numbers. Ask someone to think of a number. They should find all the cards with that number on, and give them to you. All you need do is add up the top left hand number on each of these cards. This will be the number they chose. This game is quite simple, but fun and amusing at the same time. At first this game reminded me a little bit of ‘Bingo’ but it is completely different by the time you realise how to play. i actually don’t know how this game has anything to with Binary codes, but i searched ‘Binary code games’ into google and this is what came up.
