Play, Learn, Be Happy!



Happy Blue Fish started in 2009 as one of the first mobile game designer, producer and publisher in France. We are dedicated to the improvement of individuals through gaming. We think that games are designed not only to entertain, but also to add a positive influence on people's life : learn something, feel better at home, at work, in your life, with your friends, understand the world...

In 2017, Happy Blue Fish started the askblu.ai new venture, with one vision: allow small and mid-size mobile game studios and publishers to benefit from the power of AI and Machine Learning to enhance players' experience, with no investment costs.

We believe in humanist values, respect, wellness and quality of life, solidarity and sharing, trust and truth. Great products are created by great people, great people work with fun, drive, freedom and vision.

Engage, Retain, Monetize



The first time a user launches a game, you have to touch his mind and/or his heart, so he has no choice but wanting to come back again. The first session is crucial, this is where the churn rate is the higher, so a lot of time and testing has to be spent in order to ensure that each player will not miss the added value of your game.



Once a player starts playing with your game, you've already made a big step! Now it's time to retain him/her in your game. You want each player to come back every day, every week, for several months... To do that you you need to find the good mix of engaging story-telling, fun gameplay, visual quality, rewards and incentives, and retention mecanisms...



The store is in the game, the products: fun moments, the sales force: your IP and game design... There are several ways to monetize your players, but finding the right one for each player is tricky! The key is to design the monetization process right at the heart of the game design, and to adapt it to each player .
