Jalfonso Brain Games is an intelligence game that helps you exercise your brain with 16 different minigames based on memory, math, observation skills, and logic.
In each of these mini games, you can choose between three different difficulty levels. This way, when you get the hang of one, you can advance to the next and make it more difficult. Nevertheless, even the supposedly easiest level is a challenge in some games.
Some of the minigames are genuinely quite entertaining. One that is especially good is a math game where you have to calculate exact change to be returned: you'll see a price tag and the bill used to pay for it, and then you have to choose the right coins to collect the change. Another minigame asks you to match pairs of birds.
Jalfonso Brain Games is a really fun game especially because of all the minigames it includes. Naturally some are better than others, but they all help you exercise your mind in some way.
