The classic game of Mastermind works well when solved as a whole group. The whole group must work together to crack the code. Alternatively, divide the group into two teams and each gets to set a code and try to crack the other teams code.
The game, when played like this, is a good means to teach team work and problem solving.
You could try playing the game using a projector and the online version of the game found here.
Alternatively, you could create a big set of coloured counters using cardboard and get the game to be played interactively as a "live" version.
