At Pocket Gamer Connects Helsinki 2015, Peter Willington spoke to Rovio's Teemu Hämäläinen.
He's been working as executive producer on its latest game Nibblers, a match-3 game, targeted towards women.
It's a demographic Hämäläinen has previously experienced in his time at Habbo Hotel.
When it comes to Nibblers, the team created over 20 prototypes to come up with a puzzle game that balanced luck and skill in an appropriate way for the player.
