Brain trains: strategy, coordination, perspective

Lamb Chop Drop

Play. You’re a falling lamb and you must steer yourself into the path of colorful stars flying upwards. This game trains your spatial awareness because you’re given a three-dimensional view instead of 2D. Finally, the more stars you get, the more money donated to a worthy cause – much like freerice.com.

Brain trains: spatial intelligence, prediction, perspective

Brain Age 1

Play. You’re shown a bunch of numbers scattered about the screen. The screen goes blank. Next, you’re shown placeholders where the numbers were and you have to click on the placeholders in order from least to greatest by the numbers they represented. Your brain age score is calculated after ten rounds.

Brain trains: memory, concentration, visualization, brainage

Spin The Black Circle Game

Play. Only the left and right arrow keys are used to rotate the entire screen in order to move the ball to its destination. While it sounds easy, the reality of ball physics will make this an addictive brain trainer.

Brain trains: reaction time, spatial intelligence, coordination

Fruit Smash

Play. A good Bejeweled clone. For those who don’t know what Bejeweled is, you click on a fruit and then another either to north, east, west, or south of it. This causes the two fruits to swap in the hopes of making lines containing three or more of the same fruit. The completed lines are removed and surrounding fruit move to fill in the void. It gets really fun when combos happen.

Brain trains: processing speed, pattern, big picture

Three Glasses

Brain trains: permutations, spatial intelligence, visualization

Blue

Play. You’re required to make all the tiles light up. This is done by moving the sphere. Whenever the sphere is over a tile, the four adjacent tiles to the north, east, west, and south of it are toggled to their opposite: dark tiles are lit, lit tiles are turned off.

Brain trains: permutations, prediction, visualization

Do 100 Arithmetic Questions In 5 Minutes

Brain trains: processing speed, math, reaction time

Troyis

Play. For those who play chess, you know how the knight/horse moves in an L shaped pattern? Use that type of movement to turn all the white squares purple. The blue square are off limits.

Brain trains: permutations, reaction time, big picture

8 Letters

Play. You’re given 8 letters and you have to make as many new words from them as possible (think Text Twist). Get extra points if you can unscramble the letters and find the 8 letter word before the time runs out. The idea isn’t new, but the presentation is flawless.

Brain trains: processing speed, permutations, verbal reasoning

Reverse

Play. Using your mouse, move the object through the maze, to the goal. Oh, one more thing. If your mouse moves left, the cursor moves right, and vice versa. You have to will your brain to do the opposite of what it’s been conditioned to do.

Brain trains: concentration, reaction time, prediction

Picto

Play. Click on the icon which was the newest addition to the screen. Sounds easy, but once the screen starts filling up, you’re forced to keep track of what came before.

Brain trains: memory, concentration, visualization

Ray Ray’s Parade

Play. You control a formation of cute, chubby babies. Your job is to get them all to stand up by clicking on them. When you click a baby, any other baby to the north, east, west, or south of it is affected. If the other(s) baby is crouching, it will stand. If it is already standing, it will crouch. Cute way to train you brain.

Brain trains: permutations, logic, big picture

Nodes

Play.The red nodes are connected to one another by lasers. Drag the red nodes so the lasers pass through each and every blue node.

Brain trains: strategy, multitasking, visualization

Mass Attack

Play. Your job is to balance the scales by creating balls with different masses to offset the computer-generated load. The difficulty lies in the fact that you only have a limited number of tries.

Brain trains: math, prediction, visualization

Spa Cat

Play. Given a screen full of multi-colored, multi-sized numbers, you must click them in order from least to greatest before the time runs out.

Brain trains: concentration, reaction time, big picture

Keyway

Play. Press the corresponding arrow key when you’re shown it, and press space bar when you’re shown a square. That’s all there is to it. Oh and every mistake you make, you lose 5 seconds. Every round you pass, you gain 10 seconds. Try to get as much points as you can before time runs out. Simple, yet elegant with a hypnotic soundtrack.

Brain trains: concentration, reaction time, coordination

Eskiv

Play. A simple concept, but powerfully addictive. You’re a big dot that gets around the screen using the arrow keys. Touch as many squares as possible. Avoid small dots. The catch is: for every square you touch, another small dot appears. Try to get 135 points. That’s my high score.

Brain trains: concentration, cognitive control, visualization

Excit

Play. Really fun game that uses an excel spreadsheet as its backdrop (sorry if your boss walks by, it looks like you’re doing work). Using the arrow keys, the object is to guide the ball to the green ex(c)it. Once it starts moving, the ball won’t stop so you have to steer its path using immovable objects randomly placed on the game screen.

Brain trains: strategy, permutations, visualization

Cube Field

Play. Using the left and right arrow keys, steer clear of objects coming at you at what seems to be a million miles per hour.

Brain trains: concentration, reaction time, spatial intelligence

Cell

Play. Frustrating, but in a good way type of game where your left hand controls the gray block and your right hand controls the fence around the gray block. Move both to the goal. This game works because it demands us to coordinate both hemispheres of the brain.

Brain trains: concentration, multitasking, coordination

Chat Noir

Play. Turn-based game (you and the computer take turns making a move) where you must keep the cat from escaping the play area by clicking light green circles to make them dark. The cat cannot step on dark green circles.

Brain trains: strategy, permutations, logic

Binary Game

Play. Interesting game created by Cisco Systems to train their own techs. The game involves converting bytes into whole numbers or the other way around. Has a Tetris-like feel because if you’re slow and the bytes get too high, game over.
Thanks to Jessica Bridges, for informing that the cisco link is broken and giving an working alternative link.

Brain trains: math, concentration, processing speed

Bloxorz

Play. Very well-made puzzle game which involves moving a brick into a hole.
