Jackpot! G5:
Earn a Cumulative Vegas score of 1,000 points in Klondike.
Open klondike, open settings(click on the screen and a little pops up, click the gear)
Change the draw type to 1
Chagne the Scoring type to Vegas Cumulative
Now win a game, you should get over 2k for winning, starting a new game without resetting the score, is -50 to your score, reset and goes back to -50. You get three runs through the deck before its game over. So if you can move a card move a card.
Undo does NOT void the achievement either.
For this achievement, you need to start a game of Klondike and go to the setting. Change the score type to Cumulative Vegas and complete the game (it will net you quite more than 1000 points, so it's almost guaranteed).
