A thinking game is something that stimulates and uses your mind to make it become more efficient. Below you will find a few games that will boost your brainpower.

Visualisation

The best thing  to visualise is your goals in life. Visualise what you would be doing if you achieved your goal, what kind of house you would live in, what kind of things you would hear, see, touch, taste, smell. Do this as vividly and as deeply as you can, for at least 30 minutes per week. This will help you gain mental clarity, mental direction and improve your ability to look at the finer details in things.

Chess

It goes without saying that this will help you to get your brain in top top condition. A game a day will get your spatial ability up to scratch. Also, playing speed chess, suicide chess or doubles chess provides variety and added stimulation.

Bingo

Now this might not seem a great intelligence builder but believe me it is. The speed and simplicity of bingo actually helps to maintain mental dexterity better than chess does.

Crosswords

Getting your brain cells ticking with crosswords will help you to remain cultured and make good use of your memory.

Computer Games

I don't mean all computer games here. I mean games that involve a lot of problem solving and investigative work. For example, many RPG's with their fast and furious natures will keep you on the mental edge.
