I was lucky this time as I have received 10 NOVA tokens from the airdrop. I will wait for the next airdrop which will be right after around 8 hours.
After waiting for 8 hours I again appeared on the game dashboard and I wanted to open the airdrop. As soon as I clicked the airdrop an enhancer pop up in front of me. It is an advanced normal enhancer to enhance the quality of the cards. It has a success rate of +5%.
It is available in my inventory. At first I got a normal enhancer but it did not succeed to enhance y cards instead it became unsuccessful and my all 3 cards were burnt.
Moving on the game page I saw very low energy of mine. I checked it and clicked on the recharge button. I was thinking it would be a single step task but it was not like that. To increase my energy I had to follow the following scenario.
To recharge energy I needed 20 energy flesk. And I had to buy them with my STEEM.
In the next step it shows that how much STEEM will I pay to continue this process. It displayed it will cost me only 0 STEEM.
I clicked on Confirm to boost my energy from 0 to 100% as it was coming free of cost. It showed this processing screen.
This is current statistics of my account where in total I have earned 13.490 NOVA tokens free of cost. On the other hand I am earning 1.5 NOVA tokens on a daily basis free of cost.
