Prisoner's Dilemma

Prisoner's Dilemma Prisoner's Dilemma is a game where two players should choose whether to cooperate or to compete. Shall I snitch the other one? Or shall I protect him?

But how do I know if he's going to snitch me, or not?

Do women trust more than men do?

You might be familiar with hypothesis that, when women are in charge, there are fewer conflicts, compared to when men call shots.

Since Prisoner's Dilemma is a game of trust, lets see what our data says - are women cooperating more than men are?

A bit of a spoiler: yes they are - but they cooperate more with men, rather than with other women.

How much do we trust each other?

Prisoner's Dilemma is not only a game, but can also be viewed as an instrument - measuring the trust in a group of people, even whole society.

After 2 days of test play in May, we have gathered sufficient data to publish our first analysis on how much do our players trust each other.

A small spoiler - the results are not that great!

Kao što smo obećali, okupili smo se na večeri u pančevačkom restoranu Borneo, da uručimo nagrade najboljim igračima demo verzije igre Prisoner's Dilemma.
Tom prilikom, lepo smo se ispričali, i razmenili utiske i ideje za unapređenje igre.

Prisoner's Dilemma - rezultati Demo play-a

https://prisonersdilemma.fun/

Na početku, veliko hvala svima koji su uzeli učešća u test igrai.
TOP 10 igrači su (broj odigranih takmičenja je u zagradi)

1. milanboksan 18.0 (13)
2. Soko 9.85 (12)
3. nikola93 8.65 (6)
4. Boka 7.75 (7)
5. dekky 4.15 (11)
6. goranluledzija 3.3 (5)
7. VUkan 2.9 (2)
8. Vesna 2.25 (3)
9. Giant39 2.15 (2)
10. adrian 2.0 (2)

3 prvoplasirana igrača će od nas uskoro dobiti poruke vezano za preuzimanje nagrade.

Da ali se isplati cinkariti?
Brojke u donjoj tabeli kažu - da! Ali, treba imati u vidu da su pobednici takmičenja primetili da AI igrači igraju po čistom random-u, što znači da protiv njih treba uvek cinkariti.
Zbog toga smo uradili i analizu procenta cinkarenja kada se igra protiv ljudskog protivnika - tu se uglavnom primeti blagi pad procenta cinkarenja.

Konačno, primetili smo i da se procenat cinkarenja. razlikuje ako vidite protiv koga igrate (58.3%), naspram takmičenja u kojima se ne vidi protivnik (66.7%). Ovo ukazuje na činjenicu da su ljudi skloniji saradnji kada znaju ko je drugi igrač, nego kada se igra na slepo.

Konačno, imamo i rekorde po sva 4 tipa takmičenja

1. Fantastic Four - 18 (milanboksan)
2. Six Pack - 62 (VUkan)
3. Octopus - 67 (milanboksan)
4. Decathlon - 84 (nikola93)

Takmičari uskoro treba da očekuju i našu anketu, gde ćemo ih detaljno ispitati kako im se igra svidela - što će biti ključni faktor prilikom našeg odlučivanja o daljem pravcu razvoja igre.

Još jednom, veliko hvala svima!

Zdravo svima,
Završavamo poslednje delove Prisoner's Dilemma igre, čiji demo smo zakazali za 21.5. i 22.5. 15-19h (srpsko vreme).

Malo niže možete pogledati jedan ekran iz igre, možete videti kako sam ja rasturio AI igrača rezultatom 13:10 (dobro, ako ćemo pravo, nisam ga baš rasturio!)

Što se igre tiče, imamo jednu dilemu, i tu nam treba vaša pomoć: da li prikazati protiv kog igrača igraš? U originalnoj verziji igre - to nije mogu'e, jednostavno ne yna[ protiv koga igraš - a ipak nam se čini da kada to vidiš, igra postage zanimljivija.

Takođe, pripremili smo i stranu na kojoj smo objasnili koji delovi igre će moći da se igraju u Demo-u, a koji neće. Pogledajte molim vas (na engleskom je). https://prisonersdilemma.fun/test-launch-may-21-update/

I, molimo vas, raširite glas o igri, kao bi se što više ljudi prijavilo za Demo igru - brojnost bi nam zaista puno značila!

Naša sledeća poruka biće 1-2 dana pre 21.5., sa konkretnim uputstvima (URL za igranje, URL na kom ćemo se sastati)

Pozdrav svima, hvala što pomažete razvoj igre!

Some updates on what will be there on Prisoner's Dilemma Demo run on May-21

Prisoner's Dilemma - probna igra zakazana za 21.5. - pridružite se!

Od kolega sa mnogo većim iskustvom u razvoju igara naučili smo da je igru u što ranijoj fazi potrebno testirati, kako bi se dobile važne povratne informacije od igrača kojima je namenjena.

Zbog toga se okupljamo online za 2 nedelje, kako bismo zajednički igrali Prisoner's Dilemma, a i kako bismo se malo zabavili :-)

Za one koji još nisu upoznati - Prisoner's Dilemma je igra u kojoj dva igrača odlučuju da li će cinkariti jedan drugoga, i od njihovih odgovora zavisi da li će prevladati saradnja, ili takmičenje između 2 igrača. Više o igri možete pročitati na https://prisonersdilemma.fun/game-rules/

Q: Kada se okupljamo?
A: Okupljamo se 21.5. (sreda) od 15:00 do 19:00, kao i sutradan (22.5.) u isto vreme. Dobrodošli ste u bilo kom trenutku.

Q: Da li poziv važi i za mene?
A: Itekako, molim samo da se prijavite na mailing listu (https://prisonersdilemma.fun - videćete formu sa leve strane ekrana) - kako biste dobili detaljnija obaveštenja, kako se datum bude približavao.

Q: Da li mogu da pozovem i svoje prijatelje?
A: Naravno, [to nas vi[e bude do[lo, to 'e igra biti bolja, a biće i zabavnije.

Q: Šta se od mene očekuje tokom testiranja?
A: Započnite svoje takmičenje, ili se priključite nekom od onih koje čekaju početak. Možete da igrate ili protiv drugih igrača, ili protiv bot-ova. Sama igra je laka - u 3 igre (a svaka ima po 10 rundi) treba da odlučite, hoćete li cinkariti onog drugog igrača (DA ili NE). Na osnovu toga se određuje broj godina koje svaki igrač treba da odleži - prema pravilima koje možete videti na https://prisonersdilemma.fun/game-rules. Pazite - nećete znati protiv koga tačno igrate u kojoj igri!

Q: Zašto je moje učešće bitno?
A: Vaše mišljenje će nam biti od neprocenjive važnosti: da li je igra zanimljiva, da li je prebrza ili prespora, kako je obogatititi itd itd. Mi sami imamo neke ideje, ali kako da znamo da li sviđaju i drugima, ako ne čujemo njihovo mišljenje?

Q: Kako ćemo komunicirati tokom igre?
A: Otvoriću Google Meet sastanak, link ću vam poslati koji dan pre 21.5.

Q: Imam i ja neke ideje vezane za ovu igru.
Sve ideje su dobrodošle, molimo podelite ih sa nama, kako bismo zajedno napravili što poučniju i zabavniju igru.

Vidimo se 21. maja!

Prisoner's Dilemma - test play scheduled for May-21, everyone's welcome!

Game development theory says that you should organize test play as early as possible in your project, in order to gather feedback from your users.
Therefore, we're organizing test play of Prisoner's Dilemma - it will be held in in a bit more than 2 weeks from now.

Q: When will the test play take place?
A: We will gather on May-21 from 3PM to 7PM (CET), and the next day (May-22) at the same time.

Q: Am I welcome to join the test game?
A: By all means, please do so by registering for our newsletter (form on the left side of the screen on https://prisonersdilemma.fun/test-launch-may-21/

Q: Are my friends welcome as well?
A: For sure, please invite as many people as possible – the more, the marrier

Q: What am I expected to do in testing?
A: Just start your own competition, or join the one which is waiting to start. You can play against other players, or if there are none available, against bots. Playing is easy – in 3 games (each of 10 rounds) you should decide – do you want to snitch the other player (YES), or NO. You won’t be able to know who the other player is.

Q: How are we going to communicate during the game?
A: I will provide Google Meet URL few days before May-21

Q: I have some ideas on Prisoner’s Dilemma myself!
Please share it with us, hopefully it will help us a game which will be more fun, and more educative.

Anyone ever heard of Nicky Case?

While doing research on Prisoner's Dilemma, I have stumbled across her wonderful website, with dozens of games / simulations - some explaining natural phenomenon (like synced blinking of fireflies in SouthEast Asia), others simulating social behaviour (propagation of hatred in society).

Real great stuff - not only it's educational, but also fun!

Have you heard of Nicky Case? Her work has inspired us to work on Prisoner's Dilemma game - so we felt obliged to say something about her work.

Does it pay off being nice?

When identifying the characteristics of a successful Prisoner's Dilemma strategy, professor Axelrod has put BEING NICE on the top of his list.

I have tried to dissect what being nice actually means from a psychological point of view, and to analyze the impact of these 25 traits on the game.

In my analysis I have reached a conclusion which was a bit unexpected for me, and I doubt prof. Axelrod would agree.

Please give it a read, I would like to hear your comments.

Zatvorenik koji je ispao magarac
(Prisoner as a fool - English version below)

Ljudi, treba mi vaše mišljenje.
U grafičkoj pripremi igre 'Zatvorenikova dilema' došli smo do momenta kada treba prikazati ishod u kome me je drugi igrač ocinkario, a ja njega nisam - on izlazi na slobodu, a ja dobijam 3 godine zatvora.
Dakle, verovao sam mu, i ispao sam magarac, naivčina.

Koja vam od donje dve slike bolje ilustruje ovakav ishod?
Puno hvala na pomoći!

English Version

We're working graphical solution for one of Prisoner's Dilemma game scenarios - where I have not snitched the other player, but he has snitched me. The result is - he is walking free, while I get sentenced for 3 years.
So, I have trusted him, but it appears that he has made me a fool.

Which image does represent this scenario better?

Many thanks for your help!

Prisoner's Dilemma is all about judging what works better - cooperation or competition.
Actually, this question is not really new - it has been with us since the very early days of the mankind.
That's why I have prepared a quick overview of these 2 options throughout human history.

Btw, my daughter has contributed to this article by adding some good books to read. As you will see, she is all for the cooperation, while I'm a bit more inclined to competition :-)
