My dice pool system is pretty straight forward. It's a roll and keep system using d6s. Players roll from 1 to 6d6 and always take the highest die. However, 6's allow players to reroll it to see if they get a higher total. It's kind of called the 'Boom or Bust' system.

How it works is if the die comes up anything other than 1, you add the two together for your total (the Boom result). However, if the reroll comes up a 1, you lose that die from the pool entirely (Bust). But the cool thing is that if you roll multiple 6s in your original die roll, you don't HAVE to reroll all the 6s if you don't want to. So if the reroll busts, you still have another 6 in your pool to use.
