It's a good question because on the contract address https://ethplorer.io/address/0x9fa502e35db41c242fc70611f59ae545b19059df I see only 6000 ETH but on the telegram channel, I saw someone said about reaching it.  

what is this XENON token? why it not a PKT?

Aha. And then the crypto currency will be extracted from other people's PCs

Great idea. If it turns out to implement all that is conceived. The price of the token grows unequivocally.

I tried to play a free demo on playkey.net on my office notebook. I was told to wait for 8 minutes in order to be connected to the server, so I didn't want to wait for so long.

I'll try tomorrow. Have you tried their free demo on your outdated computer?

you need to have a good internet connection if you want to play the game on playkey.
thats why you need to wait a bit longer to connect the server.

and how does this token relate to Playkey?

They collect money in ETH. For now, it is more than 7800 ETH on that address and some xenon tokens )

I think xenon has nothing to do with PlayKey.

Pre-sale is completed. ICO starts on 1 November and lasts until 30 November or til the hard cap.
