You will play two simultaneous games — one against a new partner A (same earning tier) and one against a new partner B (different earning tier).

You have {{ dictator_ec }} ECs for each game. Choose how much to keep and how much to offer to your partner.

Offers must be in multiples of 10 (e.g., keep 80 / offer 20).
Your partner may accept or reject your offer.
If accepted: you keep the amount you chose, your partner receives the offered amount.
If rejected: both of you earn 0 ECs from that game.

In the same session, you will also decide whether you would accept or reject each possible offer that could come from your partner (strategy method). This determines your earnings as a responder.

Worked example:

Role	Situation	Outcome
Proposer	You offer 30 ECs. Partner accepts.	You keep 70 ECs; partner receives 30 ECs.
Proposer	You offer 30 ECs. Partner rejects.	Both earn 0 ECs.
Responder	Partner offers you 40 ECs. You accept.	You receive 40 ECs; partner keeps 60 ECs.
Responder	Partner offers you 40 ECs. You reject.	Both earn 0 ECs.

💡 Both roles happen simultaneously. Your total earnings from each game = proposer earnings + responder earnings.
