Rogue Trader

There are 3 parts to the Rogue Trader minigame. Each allows you to buy something different from Ali-Morrisane.

Runes
After completing Rune Mysteries, talk to Ali-Morrisane. He will tell you to talk to Aubury in Varrock about a rune deal. After doing so return to Ali-Morrisane. He will say that there is an odd lock mechanism on the boxes of runes. Say that you would like to see his selection of runes. Three options will appear. "Pick Lock", "Force Lock" and "Examine Lock."



The "Pick Lock" option will work sometimes if you have a high enough Thieving level, and the "Force Lock" option will work sometimes if you have a high enough Strength level. Although it is rare for either to work. If you want to try and solve the sudoku puzzle, choose "Examine Lock."

Once you click "Examine Lock" you should see a screen that looks like this.



The runes substitute numbers in a standard sudoku puzzle. You can either solve the sudoku puzzle yourself or use a sudoku solver. If you don't know how to solve a sudoku puzzle, a guide can be found here.

After solving the sudoku puzzle, you will have the options of either choosing to buy all the runes for a specified amount of to see what the runes are first. Even if you decide to see what the runes are, you can still buy them for cheaper than what Ali-Morrisane normally sells them for.
