What we kept
What we kept
01 - Educational challenges
At the heart of Mistral's operations is the delivery of information and support for creativity and knowledge-based work. We hope that the challenges will keep this same spirit, allowing users to learn while playing.
02 - Personalized assistant
We want to make this game more playful and enjoyable, making users feel that this experience is unique.
03 - Scoreboards
We didn't choose the leaderboard score feature because Mistral doesn't have a user social network.
04 - Interactive challenges
We didn't go for Interactive Challenges because they just don't fit with the Mistral brand.
