There's a good first conditionals board game in Reward Pre-intermediate resource pack. I think the same pack also has a great second conditional mingle activity called 'dream on'.
When I teach second conditional, I often play an advice game called - 'if I were you'....
Four or five students play, and they have a pile of cards (you'll need to make these in advance) in the centre.
Student one takes the first card and reads it - each card has a dilema or problem on it, for example: "You hate your boss and your job is very boring, but you can't quit because you need the money".
The student should memorise the information rather than just reading it directly from the card. She then tells the other students her problem. Each student in turn advises them "If I were you, I'd secretly look for another job" etc etc
After hearing all the advice, the player gives the dilema card to the person whose advice she likes best. Play moves on from player to player.
When time is up (or there are no more dilema cards left) the winner is the one with the most cards (the person who has been giving the best advice).
Hope this helps - it's quite basic, but the students always seem to enjoy playing it, and it's a great way to get everyone talking. You can make some of the dilemas serious (like the job one above) and you can add some humerous ones too "My new girlfriend smells like cabbages".
