🎮 Bio-Gaz: Village Energy Entrepreneur#
Apply everything from this course. Install digesters, negotiate payment models, keep customers happy, and build a biogas business across three villages.
How to Play#
You are Bio-Gaz, a biogas technician with $400 starting capital.
Click any house to visit and start a conversation with the owner
Ask about cows, cooking needs, and budget — then propose the right digester size
Negotiate payment: customer pays outright (cash), gets a loan and repays weekly, or you install and they pay-as-you-go (PAYG) each week
A timer counts down each week — if you do nothing, the week advances automatically. Business waits for no one!
PAYG customers stop paying if unhappy — and can demand system removal if ignored
Unlock Village 2 and 3 by keeping customers happy and installing enough digesters
Game over if: you run out of money, any customer hits 0% satisfaction, or your reputation stays below 20% for 2 weeks.
