Which grows more?
Eight quick rounds. Two real options, one right answer, and the arithmetic shown every time.
Most financial mistakes are not made by people who cannot do the maths. They are made by people who never ran it, because the wrong answer felt obviously right. A 15-year loan at a slightly higher rate against a 25-year loan at a lower one. ₹5,000 a month for twenty years against ₹15,000 a month for eight. A 7% deposit against a fund yielding 9% with a 1.5% expense ratio.
Each round puts two of those side by side and asks which ends up ahead. Then it shows the working — the formula, the figures, and where the intuition went wrong. The point is not the score. It is that after a dozen rounds you start estimating these correctly in your head, which is the skill the calculators were only ever confirming.
No sign-up, no scores kept unless you want them, and every question is drawn from the same formulas the calculators use.
