PKR is a 3D online poker site. You can download the software for free which is more than 900 MB large, but if you have a slow Internet connection you can order the CD version also for free. After installing the software from the CD you still have to download a lot of updates so it is always better to use the online version if you can.
The PKR software doesn't contain any spyware or trojan. You can install an additional software which will always run in the background in order to alert you about the actual poker championships but this is optional. The software is really intuitive and user-friendly.
You can play with real money or you can play for free. Lots of people say that there are no serious players at free tables, but my experiences are different.
If you want to play with real money you can deposit via credit card or MoneyBookers. If you have Visa Electron there is an additional step because they have to be sure that you are not under 18. If you use MasterCard the money will be placed instantly to your PKR account. The minimum deposit is $25 and you also get 1500 PKR points to buy clothes and special gadgets for your 3D character.
PKR is a very nice game and beginners usually like it. If you are not a beginner, you have fair chances to win at small stake ($0.02/$0.04) tables.
