Now you can play the Beginner Level, Easy Level and the Normal Level
for free. While for higher level you have to signup.

The game works quite fast atleast on my computer.

It makes moves in 10-20 seconds. While sometimes goes for 1 minute if a
position is quite complex. But it is 100 times better than it used to
be earlier.

So you can enjoy free chess at

Play As long as you want. Your Scores will tell how intelligent you are
and will be displayed on the site.
