The UEFA European Championships 2012 in Poland & Ukraine is starting very soon, so I have created an excel spreadsheet based predictor in which you can fill in your predictions and participate in a group competition to figure out who has the best football / soccer knowledge out of your mates / group / office
You can download a free version of it HERE It features a full calender itinerary schedule for Euro 2012 as well as the prediction and sweepstake potential.
It is set up so that you can use it to host a sweepstake using it in your office/pub/family or just use it to see how you reckon the football tournament is going to pan out.
It allows for multiple players (currently 5) with more being made available for a few pennies, should be perfect for most office competitions based on the european championships.
Hope you find it useful
