TLS Brain Training has three mathematical puzzles:
Magic Squares
Discovered by the Chinese in 650 BC, magic squares are one of the oldest known math problems. A magic square is a square of successive distinct integers, in which every row, column and diagonal adds up to the same number.
Creating a magic square from scratch is a very difficult task. In TLS Brain Training, this has been simplified, so that the player only needs to fill in the missing numbers from the available tiles. There are millions of possible magic squares available, so the player is unlikely to see the same one twice.

Math Teacher
You play a math teacher, whose students have done a math test. You must mark their work as fast as possible, but as the teacher, you aren’t allowed to make mistakes!
The students’ questions and their answers, both correct and plausible but wrong ones, are generated on the fly, so there are an unlimited number of different puzzles.

Save the Environment
In this game, you must intercept all the multiples of a particular number before they fall to the ground. The multiples are poisonous and will pollute the environment if they are allowed to land.
On the first level, the falling numbers are simple multiples. On the hardest level, each falling object contains a sum, which the player must evaluate.
