Sorry for the late reply, and thanks a lot for the re-steem @roberttene! I'm not sure if I fully understand your question, but perhaps this explains it:

As a player, your miners are backed by hash power from the Hash Rush mining farm. This means that you just play the Hash Rush game, and you're not actively mining cryptocurrencies yourself.

At the same time, you can choose to join the Hash Rush mining pool and earn Rush Coin and other cryptocurrencies in the process. For this, you would of course need your laptop (or other computer).

And if you want to play Hash Rush and mine cryptocurrencies at the same time, then this simply depends on the specs of your computer. If the specs are sufficient, you should be able to do both simultaneously.

Does that answer your question?
