Zynga is heavily losing users. In our last week’s AppStats Top 10 losers by monthly active users (MAU) Zynga is represented with eight titles. The biggest loser is Zynga Bingo. The title lost almost 2,300,000 MAU last week – about 25% of their entire monthly active user base. The three next biggest losers in the ranking are also Zynga titles, namely CityVille, Hidden Chronicles and Draw Something, each losing over one million MAU.

The remaining Zynga titles in the Top 10 are Zynga Slingo, CastleVille, Empires & Allies and FarmVille. Zynga Bingo reached its peak 10,700,000 MAU after launching end of May 2012. We saw this peak last week and see the numbers declining rapidly since. Typically, those are the users acquired by ads and cross promotion from other titles that do not stick with the game.

Most of the titles mentioned did not just lose users last week.  Zynga Slingo, CityVille, Draw Something and Empires & Allies all show a very constant negative traffic trend over the last month. FarmVille and CastleVille are stable in terms of MAU looking at the last month’s figures.

The other titles in the Top 10 are Angry Birds and Tetris Battle. While Tetris Battle just seems to be struggling last week, Rovio’s Angry Birds is on a gradual decline after its hyped launch in April.
