Game 5 — Group project


🔄

Same "Group project" — but now with strangers

This is the same "Group project" you played over {{C.Economy_num_rounds}} rounds in the previous part. This time, you will play it with the Partner A ({{ ingroup_tier_label }}) and Partner B ({{ outgroup_tier_label }}).

How It Works

You have {{ pgg2_commons }} ECs. Decide how many to invest in a common pool — any whole number from 0 to {{ pgg2_commons }} ECs.

Your earnings = ECs kept + (total pool × 1.5 ÷ 3)

If everyone invests 100 ECs:
Pool = 300 × 1.5 = 450 ÷ 3 = 150 ECs each
You kept 0 → Total: 150 ECs
If you invest 0, others invest 100 each:
Pool = 200 × 1.5 = 300 ÷ 3 = 100 ECs each
You kept 100 → Total: 200 ECs
