Pack Rat - Unlock all 11 in-game themes.
This achievement is to unlock all 11 table themes. You will need a little over 2 million points to achieve this, and with the right game set-up it may take about an hour or two to complete.
Select Action Mode - Starting Speed Level to 100, I'm not sure if you can do this at the start, if not then put it to max starting speed. The first Challenge is always 3-of-a-kind and not very difficult. Basically make matches and use the RT to enter slow-motion to slow the clock and use bombs to stop it. When the challenge appears focus entirely on it. If set to lv 100 the challenge will net you 101 x 250 = 25,250 points.
Then let the game end and repeat, you will get ~ 27K in 2 mins of play, but you won't always be successful, so just keep at it and score that first challenge on highest game speed.
