Guys this is a damn good trick and I am so happy to have found it.
If you have a Airtel Prepaid spare sim and never want to recharge again then only this is useful else you might have to pay in hundreds for whatever you download.

1. De activate Mobile Office (*567#)
2. Open http://tadkalive.com from your mobile browser.
3. Click on Tadka Live Home at bottom of the screen
4. There is an advt. on top with games mentioned. Click on it
5. Download as many and whichever game you want.

If you ever recharge that account in future then you have to clear your debt first. So don't try it with your normal Sim. USE A SPARE SIM

Enjoy

Guys I am not able to post here regularly and I beg your pardon for that.
This is one good trick..do you know that you can switch off your computer in seconds and that too safely.
Here's how to do it :

1. Press Ctrl + Alt + Del
2. Go to Shutdown Menu on top
3. Press and hold Ctrl
4. Click on Turn Off

Its safe and you can check it by restarting the computer. The Disk check which you get on unsafe shutdown does not appear and the computer starts normally.

Say Thanks :)
