Harry Potter for Kinect

There are a total of 4 Blackboard dodging games. When I went into the Blackboard I had already completed the main storyline and 5 starred all storyline games. The Blackboard Dodging games all take place in the Whomping Willow mini game. For this game you need to duck high branches and jump over low branches.

To successfully complete each game you need to dodge without getting hit for 60 seconds. After you complete the Easy difficulty it unlocks Medium difficulty. Completing Medium unlocks Hard and completing Hard unlocks Extreme.

All 4 games are identical save for the speed of the branches. At each new difficulty the branches come faster. Complete each 60 second dodge for all 4 difficulties and this achievement will unlock. I found on Hard and Extreme you need to be a little more pre-emptive with your jumps as the speed is very high. This can be very tiring if you are having trouble so stay hydrated and take short breaks in between to catch your breath. The final 20 seconds is typically the trickiest as you are likely getting tired and are more likely to miss your jumps.
