In Volcano Jack, firey particles are flying outwards from a volcanic vent. Each of these particles has a card value, just like a deck of playing cards. Collect particles to arrive at the black jack sum of 21. To catch a flying particle, all you need to do is click on it. When you get 21 points, you'll move on to the next level of the volcanic girls show. Controls are easy - just click on a particle using your mouse (or finger, if you're playing the game on a touch screen device. Card values are as following: numbered cards are worth the number on them, Jack, Queen, and King are each worth ten points, and aces can be either 1 or 11.
