Right now the purpose is for players to each play a card, hoping the sum reaches the goal listed on the "Spot" card and within the number of cards required. Example: the Powerslam Spot requires a total of 12 - 15 within 5 cards. The player who achieves the goal first is the one who wins the Spot.
Players also have to work together to make sure the Spot is successful, regardless of who actually wins it. The match itself has a VP goal. Each successful Spot gives VPs. So even if you win more Spots than your opponent, if the match itself does not reach its VP goal then both players lose. I'm still working this part out.
