Six lessons in one stage. They open one by one: start at GST-1, and each lesson you finish opens the next.

Ravi’s press, Murugan’s rice mill, Kumar’s workshop and Dr. Priya’s clinic each bring their own GST question.
Each question shows the numbers it needs on its own desk, and Bablu’s calculator is one tap away. Tap a figure to put it in the calculator.
Sort items onto the rate ladder, swipe who must register, build an invoice, spot the trainee’s mistakes, sort a pile of bills, race a lightning round.
Each lesson adds a line to the order’s GST card, from the ₹10 lakh sale to the cash paid with GSTR-3B, and presses its own seal in My Ledger.
Checked against the GST law in force on 8 November 2026, including the rates from 22 September 2025. A general lesson for learning, not advice for your business. Every business and figure in the story is fictional. GST Acts and Rules on cbic-gst.gov.in ↗
