Welcome to the First Intergalactic Public Goods Games! Your goal is to earn more coins than your alien rivals. 8 aliens participate in these games (including you). Each alien represents a different galaxy, and each galaxy uses its own language. But don’t worry, NO LANGUAGE has an adaptive advantage!

In each round, you have to choose a language and try to learn the words of that language. But think carefully about which language you choose because every time you change language to use a different one, you will have a penalty of 1 coin.

Then, in the same round, you will face an alien in a public goods game in which you can either cooperate or betray.

After each round you will see a ranking of the coins accumulated by each language and each alien.

Aliens may adopt different strategies and they might change their behavior from round to round.

Remember, your goal is to earn more coins than your alien rivals. If you succeed you will be the champion of the First Intergalactic Public Goods Games!!
