However, the news the company has now had over one million downloads in its Lola Panda series does go to show that focusing on your core - even if niche - market is crucial.

"The monthly growth for our games is over 10 percent. We are expecting to reach two million downloads in just a few months," said CEO Mika Heikinheimo.

Counting your success

Games released to-date include Lola's Alphabet Train, Lola's Beach Puzzle, and most recently Lola's Math Train, which has generated more than half of the total.

"It was very critical for us to create a polished concept and great artificial intelligence," commented producer Miska Fredman.

"Children between 3 and 8 years old have totally different kinds of starting points and they enjoy different kinds of challenges when they start playing the games."
