Since then, the company has fully released six mobile games: Hay Day, Clash of Clans, Boom Beach, Clash Royale, Brawl Stars and Squad Busters, which are freemium fast-paced games and have been very successful for the company, the first two generating revenue of €2 million per day in 2013.

[5][needs update] Following its rapid growth, Supercell opened additional offices in Shanghai, San Francisco, and Seoul.

[7] Game development focuses around "cells" of five to seven people which start with idea generation and an initial review by CEO Paananen.

Before Supercell, two of its founders, Mikko Kodisoja and Ilkka Paananen, worked at Sumea, a mobile game company.

In the following year, the American Digital Chocolate bought Sumea and made the company its Finnish headquarters and Paananen the European manager.

Together, Paananen, Kodisoja, Petri Styrman, Lassi Leppinen, Visa Forstén, and Niko Derome who had known each other through work connections, founded Supercell in 2010.

Tekes, the Finnish funding agency for technology innovation, loaned them a further €400,000 and Lifeline Ventures also invested in Supercell.

The following October, Supercell raised €750,000 through seed funding, including from London Venture Partners and Initial Capital.

[9] After Gunshine's completion, Accel Partners also invested €8 million in the company in May 2011, and shareholder Kevin Comolli became a member of Supercell's board of directors.

In order to ease concerns of Supercell's investors due to the change of direction, Paananen increased the detail of progress reports.

[9] Hay Day was Supercell's version of Zynga's successful Facebook game FarmVille, an easy-to-play farm simulator.

[11] Lasse Louhento had started at Bloodhouse, and Lassi Leppinen was the chief programmer at Sumea and Digital Chocolate.

Leppinen and Louhento wanted to make a strategy game that would use a touch screen so playing would be as simple and pleasant as possible.

SoftBank and GungHo bought 51% of Supercell's shares for 1.1 billion euros which is the largest price for a Finnish private company in history.

However, it rose to the top 30 of the most downloaded iPhone apps after Supercell started an expensive marketing campaign in December 2014.

[17] On 23 March 2023, in response to the Russian invasion of Ukraine, Supercell suspended service for players in Russia and Belarus until at least 1 June.

[31] The game was soft launched on 23 April 2024 on Android and iOS in Canada, Spain, Singapore, Mexico, Denmark, Norway, Sweden and Finland.

[73] In 2020, Supercell collaborated with an animation production studio Psyop, produced a short film Lost & Crowned, was uploaded on 12 September 2020 and qualified for Oscars recognition in December.
