Also not really a board game but I really like Eleusis Express and by experience many software developers also do. The Express version is a much simpler set of rules of Eleusis: one of the player choose a rule the cards have to follow to fit in a sequence and other players have to guess it by prosing cards and havint the game master indicate wether the card fits or not. The role of game master is rolling.

It's important to insist that the game master shall not use a rule too much complex (beware "creative" SW dev!). It's almost always harder to discover than expected even with smart people.

This seems like a good option as it's just cards and we have some already. LOL on the rule part, it does sometimes get too confusing. Thanks a lot for the recommendation we are going to try it tonight with our own team.
