OBJECT:  Be the first to recognize a random tone.

GAME PLAY:  At the begining of the challenge, a reference tone will be
presented for approximately 3 seconds.  Concurrently a proportional
graphic bar display will appear as well.  Next a series of random tones
will be played (and displayed).  When you recognize the reference tone
'ring in' using the appropriate key.  A correct answer results in 500
points.  Select an incorrect tone and lose 100 points. If the reference
tone goes unrecognized then BOTH players will be penalized 250 points.

ROUNDS: Two (Note: Round 2 has no visual clues)
