Hints

More Bases Advantage:
To have a better chance of winning, you might want to build more than one base. Enlarge
the base you start out with, making it completely fortified with at least two castles. Then,
send a scout cavalry, or some other fast moving unit, to the opposite side of the map from
your base. After you have checked the area and confirmed that it is safe, send a villager
to build a castle at that location and fortify that base. This is very helpful if your enemy
knows where one of your bases is located, especially during online play. 

Fast Resources:
Use the following trick to rapidly enter the cheat codes and get resources quickly. For
wood, press Enter, type lumberjack, highlight the word, then press Ctrl + C to copy it.
Press Enter to activate the cheat. Press Enter again, then press Ctrl + V to paste the
word on the screen for activation. Repeat to get resources quickly. This may be used with
the rock on, robin hood, cheese stack jimmy's, and to smithereens codes. 

Free Ally:
When you build a market, there is a chance that a rival tribe will ask you to send them a
certain amount of wood, stone, gold, and food. When they do, click on "Diplomacy" or
press Alt + D and click "Ally" on the name of that tribe. They will become an ally free of
charge. However, when you do this you will no longer be able to align yourself with any
other tribes. This is helpful if there are four tribes in the game.
