Clash of Clans maker Supercell announced strong results for 2015, which it said it achieved “while staying true to our founding vision”.

The company’s annual revenue increased by 36 per cent year-on-year to €2.11 billion ($2.3 billion), with EBITDA of €848 million, an increase of 65 per cent.

While growth was slower than 2014 – when sales tripled – it is still far ahead of other game makers like Rovio, despite Supercell keeping its portfolio of games small.

In 2015, it only had Clash of Clans, Boom Beach and Hay Day to its name, though in 2016 it launched a fourth, Clash Royale, which it claims is the number one top grossing iPhone game in 44 countries, as of 6 March.

It also announced earlier this week that it had reached the milestone of 100 million daily active users.

VentureBeat went as far as to say: “It’s not official, but it’s pretty clear that Clash of Clans is the most successful app in the world.”

This is supported by App Annie’s rankings published in September 2015, where Clash of Clans was top of the charts when it came to games that have generated the most revenue, with Hay Day at number six and Boom Beach at seven.

According to CEO Ilkka Paananen: “These financial results are of course great… However, the real highlight for us is how we’ve been able to get here while staying true to our founding vision that was all about people.”

“We believed that if we bring together the best people, create the best possible environment for them, then with enough time and some luck, some great games will follow. Games that millions of people around the world will want to play for years and years,” he added.

He also said the company has deliberately kept itself small:  “We are 180 people where most people know each other by name, and where people work in small and independent teams, in a zero bureaucracy environment.”

Supercell’s success contrasts with the performance of another Finnish mobile games bellwether, Rovio, which makes a dozen games based on the Angry Birds franchise alone.

It laid off 213 employees back in October.
