Zynga had a good week, taking four of the top five spots on this week’s list of fastest-growing Facebook games by monthly active user. The No. 1 spot went to Zynga Slingo (which has been seeing a dramatic upswing in traffic recently), with 7.8 million MAU for an 18 percent gain.

FarmVille 2 looks like it’s starting to see some serious cross-promotion from the developer and took the No. 2 spot with 1.9 million MAU, a 173 percent traffic increase. Texas HoldEm Poker came in at No. 3 due to its 5 percent gain of 1.7 million MAU. ChefVille brought in 1.6 million MAU, a 3 percent surge that allowed the title to take the No. 4 spot. The only non-Zynga title in the top five games on the list was Kixeye’s War Commander, which was up by 1.3 million for a 33 percent gain.

Five other games on the list had traffic gains greater than 30 percent. Murzik’s Bubble Pirate Quest was up by 150 percent with 1.2 million MAU. 6waves’ Bubble Epic took in 900,000 MAU for a 69 percent increase. Peak Games’ Lost Jewels was up by 600,000 MAU, a 38 percent gain. Finally, Disney Playdom’s Threads of Mystery was up by 430,000 MAU for a 44 percent increase.
