When at https://play.alienworlds.io, click the yellow "Mine" button at the top to Mine.
After a short delay, you are ready to submit your mine. Click the button to submit it.
When you click Submit Mine, the WAX cloud wallet pop-up window will appear, asking you to sign the transaction. Click on Approve button.
And finally, you can see the amount you have mined on the pop-up. This can vary depending on many factors like land type, tools used, and planetary Trilium pot at the time. That is why we don't show a specific number here.
Mining rewards accumulated by explorers can then be claimed from the left side menu, as often as they like, though daily or weekly claiming is suggested to maximize efficiency.
