In “Ultimate Match“, duelists will be pitted against each other in a series of Match Duels!
Every 10th star you win will earn you a special prize card! To win the top prize, you need 100!!
Once you have your first 100 stars, you can continue to win prize cards for every 10 stars won as shown below. Note : For 110 star or more you got the same set of prize cards again (It’s not random like AT)
You will be awarded 30TP for every match duel won.
Like any match duel, you can draw 3 cards from current packs after the duel regardless of the result.
One of the key attractions in Ultimate Match is that you may be paired with NPC’s!
The event is open to players over Level 2 who have played a total 35 Duels or more, and it is held in Duel Academy World Server.
These are the Prize Cards from this Event:

History of Ultimate matches:
1st Ultimate Match: 2008/08/28 - 2008/09/12 (15 days)
2nd Ultimate Match: 2009/01/19 - 2009/02/04 (16 days) 144 days later
3rd Ultimate Match: 2009/05/04 - 2009/05/15 (11 days) 105 days later
This recent flood of events may seem excessive, but Konami did a very similar thing previously:
Anniversary Trial 3rd: 2008/08/01 4th: 2009/04/16
Ultimate Match 1st: 2008/08/28 (28 days later) 3rd: 2009/05/04 (18 days later)
Season end 7th: 2008/09/11 (14 days later) 9th: 2009/05/14 (10 days later)
Pack release 48th: 2008/09/25 (14 days later)
So if this pattern continues perhaps we will see the next pack released around 2009/05/28, thats my prediction.
