Now that the Facebook app directory is missing(Yes, it is), Here is a list of Facebook apps for the brain :

The list includes apps that help increase your brain power, and at the same, are addictive, fun & social. IQ tests are not included since they’re just a test of your brain and do not, as such, train your brain. Here are 10 such apps – not supposed to be in any order -

#1Brain Buddies

Tests your brain in 4 areas – Memory, Logic, Calculation & Visual – and compares the results with friends. It works best when you repeat the test every few days. It is also a good way of knowing what your brain is most dominant in and what you need to work on.

#2 Who Has The Biggest Brain?

An alternative to Brain Buddies.Has mini games in the same areas as Brain Buddies though the games are a bit different.

#3 MindJolt Games

This is a huge collection of games – Just browse the Puzzles and Strategy sections for brain games.

#4 Chess

The most popular chess app on facebook. Improves your strategy & tactics. Features include Customizable chess pieces & board colors – Option to play against the computer or player – In-game chat – Player Stats.

#5 Mahjong Zen

Works on your memory. Also helps to refresh your mind. You can also try a second version of the same game – Mahjong Zen 2 – which has different game play modes.

#6 Sudoku

The classic puzzle game from Japan – good exercise for your brain. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid contains all of the digits from 1 to 9. The app also has a challenge mode – to play against your friends.

#7 Kakuro

A “cross-sums” variation of Sudoku. Builds on your logical thinking and your mathematical skills. I personally find it to be more addictive than Sudoku. If you too are done with Sudoku, Kakuro is what you need.

#8 Reversi (Othello)

A very unique abstract strategy game. The player’s goal is to have a majority of their colored pieces showing at the end of the game, turning over as many of their opponent’s pieces as possible. Revello is another alternative app for the same game.

#9 Logic Puzzle Starters

A collection of logic puzzles including Pic-a-Pix, Sudoku, Fill-a-Pix, Sym-a-Pix, Hashi, Link-a-Pix, Battleships, Nurikabe, Slitherlink. Fun to solve, leaves you asking for more.

#10 Logic Games

Helps improve your logical thinking ability. Not really popular, but has some difficult puzzles to solve.
