You have been paired with another player. One player is the proposer and once is the responder.
The two of you will together receive {{ Constants.endowment }}. The proposer will make the responder an offer, which the responder can accept or reject. If the offer is rejected, both will receive nothing.
The proposer has the following {{ Constants.offer_choices_count }} options on how to divide the {{ Constants.endowment }} between the two players.
While the proposer makes the offer, the responder can select which {{ Constants.offer_choices_count }} offers stated above to accept or reject. After the proposer has made the offer, it will be either accepted or rejected according to the responder's choices.
