Be aware of the 22 hour time limit for Aromatic Airine, and the one day time limit for Flight Club and First Class Meal!
Most of these badges require a good deal of time. Flight of Fancy is a true marathon - pack a lunch.
Let's face it: it's unusual to complete one or two foundations stacks from ace to king without winning the game, so consider "complete foundation stacks" badges as requiring game wins equal to the number of stacks required divided by four.
For wins "in a row" badges, if you've already started your win streak and you can't win the next game, don't click New Game. Simply leave the room and re-enter it or go to another. Keep doing this until you win and it should count as "in a row". Note there's no guarantee this glitch will continue to work.
For badges requiring cards to foundation stacks, if it doesn't look like you'll win the game, be sure not to bury any 2s or 3s in your red/black columns. Get every card into the foundation stacks that you can.
Bonus cards count for the 99 Lift-Off, Frequent Flyers and Roller Coaster badges, so a winning game gives 56 cards towards the badge.
For game win or spin badges, refer to Game tips.
ALWAYS read a game's How to Play, and also check for a Hints or Tips tab and/or Tutorial. They do help!
You can pull foundation cards back down to your red/black columns if necessary. You can also move partial red/black columns back & forth between each other. These techniques are generally useful later in the game, and often make the difference between a win and a loss.
If the top card in the first set of 3 draws is an ace or bonus card, consider letting it stay there until you've exhausted all other possibilities in the game. You know you can always play it, and doing so later in the game will change which cards are accessible from the draw pile.
If you have a choice of moving two red/black columns that still have face-down cards under them, it's generally better to move the one with fewer cards under it, especially before all four kings are out and have no face-down cards under them. Chances are the larger stack has a king in it which you can then move to the newly-cleared spot - thus giving you access to both piles.
If you can move a card that will free a column, consider waiting to move it. Sometimes its same-color counterpart will come along before a king.
Try to build foundation stacks evenly when possible. If you build one much higher than the others, you'll probably have a harder time winning the game.
Take your time and examine the cards for possible moves before every click of the draw pile. An overlooked playable card might not be accessible again, and you can only Undo one move in this game (and only if the move didn't reveal any face-down cards).
Try to watch for your aces as you go through the draw pile. If they aren't there, you know you need to focus on getting to the face-down cards under the red/black columns rather than the draw cards (if you have a choice between the two, for instance).
If all your kings are out with no face-down cards under them, don't bother moving red/black columns if they have no face-down cards under them. There's no point in consolidating red/black columns or having empty spots without kings to fill them: you only take the chance of burying a card you might need.
More about First Class Solitaire
Gameplay is identical to World Class Solitaire and both games share a flight theme. However, First Class is more difficult as it doesn't have the power-ups that World Class does. If you become proficient at First Class, World Class is a breeze.
The Finish button will light up when all cards are exposed and a win is inevitable. Clicking it moves all the cards to the foundations quickly and you don't have to click or drag them up one by one.
You can rank up in this game without ever winning a game, as rank progress is based on how many cards you put onto the foundation stacks. Needless to say, winning games will put 52 cards up and make for faster ranking.
You're given an additional card-back design at Rank 5, 15, 25, 35 and 45. Cycle through your choices and assign the one you want by clicking your rank icon.
Clicking your rank icon will also display a saying about your rank, and give the percent of progress you've made toward the next rank.
Most of this game's Challenge badges were released before it had ranks & rank badges.
Often a good player will win the first game played in a room. Maybe that's just a fresh outlook (or superstition), but it seems that way.
This game is what the word "solitaire" often refers to when used generically, but it's actually called Klondike. It's been included free with Windows operating systems since version 3.1.
