Let’s take Farm Town, a recent social game on Facebook by SlashKey.

As of today, the game has 4,778,781 monthly active users.

From information gleaned from the developer and the moderators in the forums, Farm Town’s user growth is simply astounding. The game is still in beta and cannot yet be found when searching the Facebook Application Directory.

A developer (known as Bert) said that they initially only sent 12 invitations on February 1 to friends to test the game with a few users. They went from 12 users to 3 million users in 2 months with zero marketing. Today, a bit more than 4 months later, they are nearing 5 million users.

A single MAU can be expected to generate between $ 1 and $2 per month for a successful online game. Make a quick calculation. With more than 4.5 million MAU, you can see that if Farm Town is intelligently monetized, it has the potential to generate major monthly revenues. I wouldn’t be surprised to see an acquisition of Slashkey in the near future.

The game has experienced some growing pains in managing this unexpected growth. At one point, they were adding between 1 and 2 servers a week. I tried to contact the developers to get more insights but understandably, I did not get any answer. They must still be very busy adding new servers or features!

For a quick glance at what the game is about, I suggest your read Kim’s post about Farm Town.

Excerpts

As background information, here are some excerpts of information I found in their forums at different points in time.

Just to give you some idea of what we are dealing with here is some information about the game development:

Some basic stats:

• Farm Town launched on February 1st. (we did some testing in 1/31).
• Over two million monthly active users.
• We have 550K visitors per day, and we are growing about 10-20% daily.
• The game is running on 11 servers, and we are adding 1-2 per week.

It is easy to see that some growing pains should be expected!!

From 0 to 2,453,182 monthly active users in just over two months, do you have any idea how much hardware and bandwidth growth is needed to keep up?

•    Interesting that you should ask that question. I just learned some interesting information in the last few days and hadn’t had a chance to convey it yet…

The only way to install Farm Town is by following an invitation from a friend.

We needed to test how the application would perform in real life. To do this we sent it to a dozen people to test. The idea was to test with a handful of users, iron out all bugs, and then publish the application. What happened is that in 2 months, we went from 12 users to 3 million users, with 1 million users playing in a day. And we’ve been trying to slow growth since day one.

Currently our servers are processing 4,000 requests per second, and transmitting 200 MBytes per sec. To put things in perspective you would need 1300+ DSL lines to serve this much bandwidth…

Please note that we are not the makers of Farm Town. We are not related in any way to Slashkey, the creators of Farm Town and we do not know how to contact them. We just wrote about their game.
