This page basically explains itself. You click this link when you wish to buy some more land for your kingdom. The page also displays a 24 hour land queue showing you how much land you have incoming in the next 24 hours.

TIP: The rule of 24 is a popular rule known by most seasoned gamers. You do NOT have to use this strat, it is completely up to you. The land goes into the 24 hour queue starting at hour 24 and moving toward hour 1. If you explore 24 land, you will have 1 land per hour. If you explore 10 land, you will be exploring 1 land from hour 15 through hour 24. A lot of players like to only build land in groups of 24 to gain their land quicker. If you have never used this strat before it may be hard to understand why it gives you land quicker.

See the below scenario to illustrate how it works but only read it if you have the time to sit and think about it… otherwise it may just confuse you more:

Scenario: You want to build 48 land, but you only have the money to build 36 land.

*If you just explore max that you can afford, 36 right away: That will give you 1 land from hour 1 through hour 12 and you will have 2 land from hour 13 through hour 24. Then next hour you want to build the additional 12 land. You have gained 1 land from the hour tick, all additional land moved up one hour leaving hour 24 with zero land. Building that additional 12 land will now give you one land from hour 1 through 11, two land at hour 12, three land from hour 13 through 23, and one land at hour 24. So if you notice, even though you’re building 48 land, you are still only gaining one land per hour for the next 11 hours.

*If you use the rule of 24, and same scenario as above: You build 24 land giving you one land per hour. You wait until the next hour so that you have enough to build the additional 12 land that would make it an even 24 land again. You will have two land per hour with one land at hour 24. If you compare that to the exploring max strat above, you will notice that even though you are waiting an hour or two to build the land in groups of 24, you will receive your land quicker.
