Landowners can pay for being at the top of the land list. It means when a miner selects land to mine, he will see your land first!
To use this cool feature you need to go to the Lands section. Click Promote button on chosen land. Then you need to select the number of days you want your land to be promoted. The minimum value is 1 day, maximum is 10 days.
There are only 10 available spots for land promotion on each sphere (Oil, Gold, Iron).
One more requirement exists for land owners, to be able to promote the land, it must have a 5% fee on it.
Price for 1 day of promotion: 8 Oil + 16 Gold + 32 Iron.
