The Slingo Promotion was originally released on the March 16th, 2012. Slingo is Zynga's latest game and as a reward for trying it out to level 5, they reward the players with 3 free Mystery Game Darts. There was a Slingo billboard on the outskirt of the farm located at the bottom, a simple click on "Play Now" for quick access. Zynga offers these promotions as an incentive for FarmVille players to play one of their other Zynga games.
