How Mentilus works: brain training that adapts to you
By Gray Matterson03 July 2026
What is Mentilus?
Mentilus is an online brain training platform built around games. Each game starts from a well-known cognitive task and turns it into something you actually want to play. Instead of dry exercises you get short challenges for memory, attention, thinking speed, perception and logical reasoning. Train for about ten minutes a day and you keep the skills you lean on all day in shape.
How a training session works
Every game adapts to you. When you improve, it gets harder, so you always play right at the level that stretches you a little without tipping into frustration. That is the level where training pays off most. After each game Mentilus saves a score based on your speed and accuracy, and those scores feed your Brain Fitness Index. One number lets you follow your progress over time and see where you stand next to other players.
Why people train with Mentilus
The biggest reason is that it’s fun. A few minutes between tasks feels like doing something for yourself, and the games make sense the first time you play them. Users tell us they feel sharper and more focused in daily life once training becomes a habit. And because the difficulty moves with you, it works as a quick mental warm-up just as well as a steady daily routine.
What you train
Mentilus covers five cognitive areas, so you never get stuck drilling a single skill. There are games for memory, for attention and focus, for thinking speed, for perception and for logical reasoning. Mixing them keeps the training varied and keeps your brain guessing. Browse our
