>>149796531 (OP)1) Football ("soccer") sized playing field, but make it oval, for shits and giggles, goeal at either end.
2) Two teams consisting of 3 field players and one goal keeper try to score goals with a ball, which can be handled any way you want.
Scoring a goal nets you 10 points. Not 1, but 10, because bigger numbers are more exciting.
3) Each team also gets two so called "beaters" whose job it is to distract or injure the opposing field players by throwing or shooting massive iron balls at them.
4) Now, here's the real selling point: None of that really matters, because while all of this is going on, there'll also be an easter egg hunt on and around the playing field, where an additional player for each team (let's call him "seeker") is tasked with finding a hidden object (let's call it "snitch", because that rhymes with "snatch", which is funny). Once a seeker finds the snitch the match is over and his team wins - unless the goal difference is over 150 (actually 15, but times 10 as explained before), in which case the seeker is supposed to stall until the difference drops below 150.
Ingenius, isn't it?
