This cheat is a bug in the game.
First save almost all of the money that you can during the game.
When you have over 35,000 crowns, trade with the Merchant.
Then just buy ANYTHING YOU WANT, but you must spend OVER 35000.
Now you will gain back your money and still get all of the Items that you buy.
Extra Stone And Wood
Begin game play and build a castle using 3 tons of wood and 5 tons of stone. After the castle is completed, extend the boundaries with a few extra walls, a gatehouse, and a moat. Select "End Design" and immediately demolish the castle before it is built to access 65,000 tons of stone and wood.
Wait for a merchant to appear, then sell 100 stone four times, and buy 2,000 of each weapon. The gold total will increase instead of decreasing. Note: Do not purchase more than 2,500 of each weapon or money will be lost.
