This brain training software offers free mental exercises and games for all ages, including memory training, mental arithmetic, and speed Sudoku. Users can compete online and compare their scores in different leagues.

While playing the Arithmetic game, you will be asked to solve math equations at top speed without the help of any tools. Mnemonic is a game that flashes numbers or numerical series at the player, which he has to reproduce correctly and as quick as possible. Speedoku, on the other hand, requires the player to complete numerical series in the style of Sudoku.
BrainSpeeder challenges even the best players with its refined online league system and the "Hall of Brain" that allows players to match themselves with others worldwide. Only the player who correctly (and quickly) solves his tasks can ascend to the next league at the end of the week. Moreover, a "Brain of the Day" will be nominated daily, and cup ties offer opportunities to compete with others in two-party teams in a sudden death-system.
For those who prefer not to play online, you can still keep your brain cells fit by playing BrainSpeeder's brain games on your home computer without an internet connection. With BrainSpeeder, you'll have fun while training your brain and becoming quicker at solving mind games.
