We're often GREE-this, Mobage-that, and Zynga-the-other.

Sure, those are the big billion dollar companies but there are also plenty of fast-growing niche players when it comes to social gaming networks.

One such is Polish outfit Tequila, which has just announced that its Tequila Planet mobile platform has reached 20 million unique users.

This is up from 10 million users in May 2012.

Supporting Android, iOS and Java games, its audience is split roughly 30 percent Europe, 30 percent Asia and 18 percent South America (with the remaining quarter spread elsewhere). Significantly, it's not yet actively expanded into the lucrative North America market.

Friends together

Tequila's EVP Lukasz Deszczulka explained the platform's mainly organic growth had occurred as its integrates with thirdparty app stores, OEM stores and number of mobile portals.

"We acquire traffic from our partners and then share in-app revenue with our affiliates and game developers," he said.

"We can do this effectively because we operate our own, operator-based in-app billing infrastructure and we have a unique user and partner tracking capability."

Tequila's billing system supports 400 operators in more than 80 countries.

Cash converters

In terms of additional metrics, Tequila says that its platform has hosted over 200 million total gaming sessions and around 18 million hours of play time.

More than 1.4 million users have converted into paying users - that's a 7 percent conversion rate - with over $2 million generated via 2.3 million purchase transactions.
