In the third-quarter Challenge of 2009 (2K9Q3) the cadets played very few matches, so their results are unreliable.
Instead, the struggle between the Veterans shows interesting results:
The demoted veterans are: DarkSoldier, Jimbo, 854bytes, GulleFjun, Errata, Bosozoku, Janeway, Butterfly, FlameBall, RoboOlm, Teddybear, KillerBees. We can see that the old aged KillerBees is going to fight against the poor cadets again.
The survivors are: Mouth (DT), Tinker (D), KillJoy (D), Bohan (DT), HellFire (ST), Stately (ST), DOOM (788), Multiple (6-5-14), IonStorm (534), StrangeMatter (423), Starkle (345), Spike (262), Tango (111). A small maniple of new robots achieved the requested percentage to survive in at least one category. In particular, Multiple has got very interesting percentages of success in all the categories, but there are still margins of improvements in team category.

Finally, in the second-quarter Challenge of 2009 (2K9Q2), we have enough played matches among the cadets, so some of them will struggle again to survive in the Cadets' League.
The results of the fight among the restricted number of veterans (only six) show only the demotion of TTL, while Tango (1-1-2), Spike(2-6-1), Starkle(3-4-4), StrangeMatter (4-2-3) and IonStorm (6-3-5) are waiting for the 21 promoted cadets.
The promoted cadets are: DarkSoldier, 845bytes, Jimbo (single and double), RoboOlm (single and team), Janeway, Earthworm, Bosozoku (single and double), GulleFjun, Teddybear, Mouth, Butterfly, HellFire, Tinker, Bohan, KillJoy, KillerBees, Stately, DOOM and the new Multiple (single, double and team).
The survivors are: Genuine, Touche, Shark, Ender, AronsRobot01, RoboScape, Nemesis, S, DeathIncarnate, AronsRobot02, Vampire, Berserk, DeadDuck, MarukoV4, RatBot, EvilElmo, Yoda, Shrike, Snutteplutt, Ladubug, Hal9000, Dragon, Grappelli, DirtyCoward, Singularity, Bizarro, CounterStrike, Headhunter.
The jrobots removed for their poor performances are: SuperRabbit, AntiBot, GenuineA.

Now you can upload your jrobots to win the July-September 2009 JROBOTS Challenge (July 4^th-September 26^th 2009) aka JROBOTS 2K9 Q3!

The first-quarter Challenge of 2009 (2K9Q1) made a great selection between the veterans. Only six of them survived and will fight one against the others for the next three months: TTL (6-5-6), Starkle (5-4-5), IonStorm (4-3-4), StrangeMatter (3-2-3), Spike (2-6-1) and Tango (1-1-2). All the others were demoted to cadets: GulleFjun, KillJoy, Mouth, Bohan, Tinker, KillerBees, Stately, HellFire, DOOM, Headhunter. They are going to have fun among the cadets, but also some of them will fail to be promoted again.
Among the cadets nothing interesting happened because the matches played were too few to be considered significative.

Now you can upload your jrobots to win the April-June 2009 JROBOTS Challenge (April 4^th-June 27^th 2009) aka JROBOTS 2K9 Q2!

The January-March Challenge ends now! The official results will be available on Saturday, April 4^th 2009, please be patient!
The next tournament will be the April-June 2009 JROBOTS Challenge (April 4^th-June 27^th 2009) aka JROBOTS 2K9 Q2!

The final Challenge of 2008 was very poor in matches for what regards the Cadets' League, in fact no new jrobots were uploaded and the only three appeared in the arena were copies of the sample jrobots included in the SDK (Simple, Rook, Sniper). Of course, I removed them from the arena for their poor results and no other jrobots was promoted because the number of matches is too low to consider the percentages reliable.
In the Veterans' League, the usual struggle between the stronger jrobots has given a few results different from the usual ones, but the final outcome is more or less the same as in the past challenges.
Among the veterans the results are:

• Survivors: GulleFjun, Mouth, Bohan, KillerBees, (for their results in team category) KillJoy, (for its result in double category) Tinker, (for its result in double and team category) Hellfire, Headhunter, (for their results in single and double category) DOOM (10-12-8), Stately (9-19-11), TTL (6-5-6), IonStorm (5-2-4), StrangeMatter (4-3-3), Starkle (3-4-10), Spike (2-7-1), Tango (1-1-2).
• Demoted: Vampire, AronsRobot02, MarukoV4, Dragon, FlameBall, Grappelli, Butterfly, RoboOlm, Earthworm.
