This starts part 1 during chapter 1 and then finishes of during chapter 2.
Part 1.
Enter the Black wand magic shop on cornmarket street in oxford town centre and play around with the game machine. look at the deadalus sign at the bottom and the 21 sign at the top. The idea is to get the cards to read 21 to win. after you win the prize will be on the right side of the game machine.

It is a riddle and starts the "THE BETRAYER'S PRICE" puzzle.

Go to oxford town and enter the carfax tower, when you get to the top close the door to reveal a red deadalus box. examine it and use your matches on the bottom (fire) to reveal a gold peice and your next clue.

Go to christ church and examine the pond and the box. Select the pond to grab a few drops and put the water on the paper square on the box to reveal a mechanism(water). this opens the box for your next clue and another gold piece.

Part 2- Chapter 2

The next clue leads you to the windy dog pub but it was closed in chapter 1. Not any longer.

In chapter 2 enter the pub and examine the horn and blow into the end(wind).
It aint right so talk to the bar tender and he will give you a mouth piece so now use that on the horn and speak with the barkeep again and he will give you another gold piece and the next clue.

Head the christ church again and enter the nave on right side of screen and then talk with guide for bonus points then head to the alter.

Activate the switch on the right side to open the small pool and reveal a bag type thing, grab that for the final gold piece and clue. Close the pool again and head to oxford town center.

Assemble the jigsaw gold pieces to reveal the final clue. it has some letters and some pictures, 1 of the pictures is carfax telephone box.
The leters mean JUDAS and that translated on a phone is 58327.

Lift the telephone and dial the number to solve the riddle and recieve a deadalus coin and 1 cheevo.
