Payment Mania

I built a free browser game where you run the lunch rush at Byte Burger. Serve customers, swipe cards, and try not to go broke while you wait for your money to settle. You might accidentally learn how card payments really work. Interchange fees, chargebacks, ACH, wire transfers, all of it.

Play Payment Mania. No signup, just open it in your browser.

What you'll get

• Run the lunch rush. Take orders, grill, plate, and serve before customers lose patience — a fast, juicy time-management loop.
• Feel how money really moves. Cash pays instantly and free; card sales settle two days later (T+2), and you can only spend cash that has actually landed in the bank.
• 30 upgrades, each a real payments lesson. Interchange vs. processor markup, chargebacks and disputes, ACH payroll and NSF fees, 3-D Secure, tokenization, and same-day wires.
• A Payments Codex. Every concept you hit becomes a plain-English card — collect them all to unlock Endless mode and a New Franchise+ prestige run.
• Free, no signup. Opens in any browser on phone or desktop. You learn how payments work almost by accident.
