This is the same "Group project" you played during previous Part.

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

The total invested by all 3 members is multiplied by 1.5 and divided equally among the three of you.
You keep all ECs you did not invest, plus your equal share of the pool return.

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

Examples:

Scenario	Your earnings
Everyone invests 100 ECs	Pool = 300 × 1.5 = 450 ÷ 3 = 150 ECs
You invest 0; others invest 100 each	Kept 100 + pool share 100 = 200 ECs
You invest 50; others invest 50 each	Kept 50 + (150 × 1.5 ÷ 3) = 50 + 75 = 125 ECs

💡 Investing more increases the total pot for everyone, but you personally keep less. Your slider lets you choose any amount from 0 to {{ pgg2_commons }} ECs.
