Complete game guide

A true-or-false quiz on financial claims people really repeat. Each of the twelve claims is judged with a confidence attached: a certain call pays more and a certain mistake costs one of three credits, so the round measures how well you know what you know.

The goal

Money Myth Buster puts twelve circulating money claims in front of you, one a screen, and asks two things at once: is it true, and how sure are you. Claims rotate through spending, scams, borrowing and tax, the economy and investing, and both verdicts are equally common — six true and six false every round — so guessing one way never pays. There is no clock and no sign-up. A round takes two to three minutes including the time you spend reading the corrections, and it can end early: three certain mistakes close it out.

Controls and play

Tap one of the four buttons, or press 1, 2, 3 or 4. The top row means certain, the bottom row means probable; the left column means true, the right column means false, and that layout never shuffles. Tab moves focus and Enter or Space selects. A freshly dealt claim ignores input for six tenths of a second so a burst of taps cannot carry over from the previous screen. After every judgement a card appears and waits for continue — nothing advances on its own and nothing times out. Leaving the page or switching away pauses the round and keeps the screen you were on.

Points and streaks

A correct call is worth 100 base points, multiplied by the claim's difficulty weight, by your confidence, and by your current streak multiplier, rounded to the nearest whole number. Easier claims weigh 1 and harder ones 1.3. A certain call multiplies by 1.5, a probable one by 0.6, so hedging every claim caps what a perfect round can be worth. The streak multiplier rises by 0.5 every second correct call in a row and stops at 2.5 times, which a twelve-claim round reaches on the seventh. A wrong call scores nothing and resets the streak; if it was a certain call, it also costs one of three credits.

Finishing and results

The round ends when all twelve claims have been judged, or when the third certain mistake has been read and acknowledged — the last correction card always appears in full before the round closes. Grades need a full round for the top two bands: S is all twelve claims judged and every one of them right, with no certain mistakes and at least six certain calls; A is a full round with at least ten of the twelve right and at most one certain mistake; B is about seven in ten right, C is around half, and anything below is D. A round that ran out of credits cannot score above C however accurate it was. The result page also gives two separate accuracy figures — one for your certain calls, one for your probable ones — and that gap is the thing this game measures.

Replay and progress

Reloading returns you to the exact screen you left: the claim you were reading, the fact card after a correct call, or the correction card after a wrong one, with your score, streak, credits and judged claims carried over. The result page lists the corrected facts for the claims you missed, because the ones you got right already showed their fact on screen, and it states how many claims were never shown if the round ended early. Play again deals a new round, choosing between eight candidate deals to repeat as little as possible, while a round opened from a shared link replays that same deal. Progress and your best score live in this browser only and cannot be recovered after clearing site data.

Language and context

English and Chinese are written separately rather than translated. Every claim is chosen for the mechanism it tests — unit price, progressive brackets, diversification, scam signals — so nothing here depends on one country's rules, and figures that only hold in one jurisdiction are deliberately left to the regional quiz. Because the two banks line up claim for claim, a shared round link deals the same round in either language. Where each claim actually circulates is recorded in the data file for review and is deliberately never shown on screen.

This round covers

Unit price beats pack size

Divide price by quantity before comparing packs. A bigger box is not automatically cheaper per gram, and the shelf tag rarely says which one is.

Source: Unit price = price / quantity

Percentage changes do not cancel

A price that rises by a percentage and then falls by the same percentage lands below where it started, because the fall applies to the raised number.

Source: Successive percentage change on a stated base

Minimum payments are not control

Interest keeps accruing on whatever is left, so a balance can grow while every payment arrives on time.

Source: Interest charged on the outstanding balance

A higher bracket taxes only the extra

Under progressive brackets the higher rate applies to income above the threshold, so crossing one never leaves you with less than before.

Source: Progressive bracket arithmetic; rates unstated

A flat monthly fee hides the real rate

The balance falls each month while the fee stays flat, so the effective annual rate is higher than the monthly figure suggests.

Source: Effective annual rate on a declining balance

Diversification has a limit

Spreading holdings removes the risk of one company failing. It does not remove the risk of a whole market falling, because those holdings fall together.

Source: Idiosyncratic risk against market risk

Real return is what is left after inflation

A positive interest rate can still be a loss of purchasing power. Two percent against three percent inflation is a loss no statement shows.

Source: Real ≈ nominal − inflation; rates unstated

Yearly fees compound against you

A percentage fee is charged on a growing balance every year, so its drag builds over a long horizon rather than staying flat.

Source: Stated fee rate applied yearly to the balance

Inflation is an average, not a rule

It measures a basket, so some prices climb quickly while others barely move. Your own basket can rise faster or slower than the headline.

Source: Consumer price index as a basket average

Signals a scam is running

Pressure to act within minutes, secrecy, a request for a one-time code, a promise of high return with no risk, and a payment method that cannot be reversed.

Source: Signals common to published consumer guidance in both markets

Questions people ask

What is Money Myth Buster?

It is a true-or-false quiz on money claims that really circulate, where each answer also carries how sure you are. Twelve claims arrive one a screen with four buttons — certain true, certain false, probable true, probable false — and every claim ends with the correct fact whether you got it right or not.

Why does the game ask how confident I am?

Because being wrong while certain is a different mistake from being wrong while hedging, and only one of them is worth correcting urgently. A certain call pays two and a half times a probable one and costs a credit when it misses, so the result page can show two accuracy figures side by side: how often you were right when you committed, and how often when you did not.

Are the false claims real things people say?

Yes, and so are the true ones. Every claim in the bank is recorded with where it circulates and when that was checked, and roughly half of them turn out to be true, which is deliberate: a quiz where everything familiar is false only teaches distrust of anything you have heard, not how to check it.

What money myths does this game cover?

Ten mechanisms, each one sitting behind claims that really circulate: unit price against pack size, percentage rises and falls that do not cancel out, minimum payments, progressive tax brackets, a flat monthly fee against the real rate, the limits of diversification, return after inflation, yearly fee drag, inflation as a basket average, and the signals of a scam. A round deals twelve claims across spending, borrowing and tax, investing, the economy and scams, with both verdicts equally common.

Does paying only the minimum on a credit card keep the debt under control?

No. Interest continues to accrue on the part you did not pay, so the balance can grow even while every payment arrives on time. The minimum is the amount that keeps the account in good standing, not the amount that reduces the debt, and the gap between the two is where a balance quietly becomes long-term.

Does earning more and crossing into a higher tax bracket leave you with less?

No. Under progressive brackets only the income above the threshold is taxed at the higher rate, so the extra earnings are taxed more heavily but the earlier income is not. The belief survives because a payslip shows one combined deduction, which makes the higher rate look as if it applied to everything.

Does holding many different shares protect you from a market crash?

No. Spreading holdings removes the risk that one company fails, which is real and worth removing, but a market-wide fall takes those holdings down together. Diversification is protection against a specific accident, not against the weather, and reading it as both is one of the most common misreadings in the bank.

Is it free, and is there a time limit?

It is free, with no account, no download and no clock. A two-way question under a stopwatch only produces guessing, and guessing is exactly what this round is built to measure, so both feedback cards wait for you to press continue instead. You also never type a figure of your own — every answer is one of four buttons.
