Art Style: Precipice Cheats for Nintendo DS
The Relax Rooms are unlocked by getting line combos on 'Ten Floors' mode. At the end of the 'Ten Floors' game you will get a video from a Relax Room, the colour of which will depend on either the highest colour of line bonuses you acheived or the next highest if you already have that Relax Room. There are a total of 9 Relax Rooms.
When you have unlocked ALL of the Relax Rooms the Final Ending and Credits will become available.
