10. Zynga Slingo
Ah Zynga, you've got your claws around Slingo as well? I remember back in the day when I would play Slingo in browser on the Sling website. It was fun, addictive, and a blast chatting with other people who were playing as well. DD (dirty devil), LOL (lots of luck), and WTG (way to go) were some of the things I remember from playing the game.
Slingo is a mix of bingo and slots where you only have twenty turns to fill your card. Each turn you have to pull the lever to get a random selection of numbers in five columns. You must match each number to their respective column; unless you don't have any matching numbers then you just pull the lever again and go to the next turn. Jokers give you the ability to pick any number in the column, coins give you more points, and devils halve your coins while cherubs save you from the devil. During the last four turns you must pay 500, 1000, 1500, and 2000 points respectively to go to the next turn. That is unless you have free spins which pop up randomly during your game play. The player with the most points or the player with the most points and a full card wins.
