Is there any way to get Regolith on the Red planet other than buying, it's really expensive on the Galactic board of Trade.
Also, can you have to worlds on the same device(Samsung)?
You can use the Galactic Freight, Space Elevator and Star Gate to buy it (with Evil Empire tax). Sometimes it's cheaper to buy it as compared to the GBT offers.
I had 4 colonies on one device (Samsung J2 Prime), but you can only play one colony at a time.
