$10 Tournament on Saturday, May 30

jasonrohrer · 2015-05-29 20:00:33

A 4-hour tournament will run on Saturday, May 30, 2015, starting at 11am PDT (Los Angeles time).

The entry fee is $10.00

The entry fees go directly into the prize pool and are not used to fund your matches in the tournament. Your tournament matches must be funded out of your remaining account balance after your entry fee is paid.

The target game stake for matches in the tournament is 50 cents.

You will see this stake level highlighted in your client. Only games played for 50 cents count toward the tournament. If you have entered the tournament, you will be blocked from accidentally joining 50-cent games with non-tournament players. However, you can still play at other stake levels during the tournament---those games will not affect your tournament standing one way or the other.

The winners are determined according to who has the most net profit at 50-cent games against other tournament players by the deadline. Play as many or as few games as you want during the tournament---it's profit that counts.

A leaderboard is here, along with a count-down:

If you want a preview of prizes for various numbers of players, look here, where the hypothetical prizes for a 20-player tournament are displayed:

Prizes will be paid automatically into the winners' account balances within four minutes after the tournament deadline.

Note:

To prevent collusion between accounts, you will stop being partnered with another player after net profit of 100 cents or more has moved between you. Thus, you cannot win by feeding off of one fish player or dummy account repeatedly. If you are winning and losing back-and-forth against a given player, however, you can play an unlimited number of games until the net profit for one player from that pairing crosses the 100-cent mark.

Note:

I just realized that the prize structure doesn't make sense for 6 or fewer players (where everyone gets a prize and the winner doesn't get very much). I'm going to tweak the algorithm a bit to better handle those cases. Eventually, it would be nice to have automated tournaments running throughout the day, and to support that, the prize structures need to make sense even if there's only a handful of players in each one.

jasonrohrer · 2015-05-29 20:26:47

Okay, I fixed this by setting the min prize to be equal to the entry fee ($10), so no one wins less than their entry fee. This makes it work better with 2-6 players.

I also adjusted the prize increase ratio from 1.5 down to 1.25. This is how much bigger the Nth prize is over the N+1th prize. By lowering the ratio, this allows more places to receive a prize.

I really like this tournament structure, and would love to play, but I'll probably be on the beach. Sorry.

claspa · 2015-05-29 21:33:21

pretty cool! I hope that until the start of the tournament my internet is working as promised.

shotgun · 2015-05-29 22:39:31

aw man, here's hoping for some more on other days, i'll be at work

.. · 2015-05-30 00:33:22

Hmm, I would take part, but Google Codejam round 2 starts at 2am my time and this is at 6am after a 90 min break. Makes it pretty hard to do both.

I am at a roguelike developer's conference, wooot, so don't think I will be able to make it. I do want to force people to play CM sometime this weekend though. I would kill for a face to face game.

joshwithguitar · 2015-05-30 04:49:27

I'm debating whether I am going to get up at 4am to play this...

claspa · 2015-05-30 10:14:28

I won't be able to participate, internet at my new place is not working.

Professor Chin · 2015-05-30 11:25:16

I hope the Amulets contest cash prizes will be handed in before the tournament starts, so my balance would be higher than the entry fee

I think others are in the same situation.

I get up at 4am and I was the only one playing 20 mins in...

Luckily Chin Professor joined .

jasonrohrer · 2015-05-30 18:31:33

You guys just got one more person.

Who will win the coveted $15 prize?

joshwithguitar · 2015-05-30 19:03:50

You possibly should have waited until after handing out the Launch Tournament prize money before holding a $10 comp Jason.

Now is the possibility of winning $5 worth getting up at 4am for...
(edit: well make that $10, another player has joined!)

Yeah, handing that out on Monday. I wanted people to have a chance to complain about mistakes after I posted the list.

joshwithguitar · 2015-05-30 20:33:04

Join the tournament now to earn instant 3rd place, with a prize of $15.6098!

(and also boost the top prize by $3....)

claspa · 2015-05-30 21:39:51

At the current tournament had many players a negative profit and I realized that by joining in the last couple of minutes and by not playing you could cheesily grab a few dollars.
I think this should be systematically prevented. Maybe by having to have played at least one game.

Which got me thinking that maybe you could change the system so, that by playing the first tournament game you cash in.
So instead of having processes like this: 1. Cash in 2. Look for a game 3. Have an opponent, pay match stake
You could try: 1. Look for a tournament game 2. Have an opponent, cash in & pay match stake

jasonrohrer · 2015-05-30 21:50:14

Well, this is an interesting consequence of a profit-based win metric.

It's better to play no games at all then to play and lose money!

Who is more skilled in this case?

I agree that the money could be debited when you play your first match. This would help with the problem of one person joining a tournament alone for $10 and winning their $9 prize. I'll think about this.

joshwithguitar · 2015-05-30 22:01:02

And poor Chin Professor was robbed at the last minute of $12 by JA joining!

I might be a little biased here but $27.44 doesn't seem like much of a winning for top place in a $10 tournament against 8 other opponents.

Professor Chin · 2015-05-30 22:12:35

After winning at the last minute a game that would allow me to be among the prize winners I notice JA just joined the tournament and was ahead of me without playing any games...

Refreshing the leaderboard after the adrenaline rush to find it out was awful

claspa · 2015-05-30 22:29:01

I really feel for Professor Chin here.

It is a bit "I told you so", JA joined within the last two minutes of the contest. This would have been prevented by making him eligible after finishing their first game.

Professor Chin · 2015-05-30 22:40:07

Ironically if I didn't gave Jason his share of the coins during the games my tournament profit would have been positive and I'd win a prize anyway...
punished for paying the taxes? :_)

BTW congratulations to Josh! He dominated from start to end.

jasonrohrer · 2015-05-30 22:42:11

The legend of JA continues...

I hear you, Josh. I think the prize ratio needs adjustment. The way it works is there's a minimum prize, in this case $10. Then there's a prize ratio, which is the factory by which each prize is larger then the next one on the list. In this case, it was 1.25. So, everyone wins 25% more money than the next person down on the list.

The server solves using these constraints to hand out the entire prize pool.

The result is that a higher first prize can be achieved through two mechanisms:

1. Raising the minimum prize.

2. Increasing the prize ratio.

In past tournaments, the lower prize was smaller and the ratio was 1.5

We could imagine raising the ratio up to 2.

In this case, $81 in prize money was available. So we could have roughly $46, $23, and $11.50 as the top 3 prizes.

According to this sentence JA's profit at 50-cents games is not zero, it's non-existing

I guess the PHP sever didn't study philosophy though...
