IMHO the easiest of the new table achievements.
Right above the center of the table, spelled downwards, is a ramp with ARENA under it.
Simply hit the ball up the ramp to light each letter one at a time and then one final time as they are all flashing and lit.
The screen will freeze then zoom in and transport you to the arena. Give it a few seconds because the achievement doesn't pop until the quick animation of the arena being set up is finished.
