Kuburi	Visuospatial ability According to the classic Baddeley model (1992), the visuospatial agenda is part of working memory. Cognitive flexibility	Participants must create a drawing by using the face and orienting some cubes.
Teka Teki	Planning game	Participants can obtain a key if they can help the fox follow her path to the lock. However, the path is obstructed by different blocks. The number of possible movements will decrease, thus increasing the difficulty.
