Welcome to the First Intergalactic Public Goods Games! 4 aliens (including you) are taking part in these games. Your goal is to score as many points as possible.

In each round, you first have to choose a language that you will use to play the game. From round to round, you can change your language if you wish, but it is important that you memorise your language well in order to compete with other aliens.

After choosing your language, you will face an alien in a strategy game that determines how points are distributed.

After each round, you will see a ranking of the points accumulated for 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 score more points than the other aliens. If you succeed you will be the champion of the First Intergalactic Public Goods Games!!
