You have been paired with another player. One player is the proposer and once is the responder.
The two of you will together receive {{ C.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 {{ C.OFFER_CHOICES_COUNT }} options on how to divide the {{ C.ENDOWMENT }} between the two players.
While the proposer makes the offer, the responder can select which {{ C.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.
