Fact-Checking Policy

Most of what this site publishes is checkable in one of two ways: by reading the source code of the game being described, or by testing the browser behaviour being described. This page sets out how that happens and what to do if we get something wrong.

Last reviewed: 15 September 2026.

The three kinds of claim we make

Claims about our own games

For example: "the dash cooldown is about two seconds" or "the generator never places two crumbling platforms in a row". These are verified against the game's source code and confirmed by playing it. This is the strongest category of claim on the site, because we control the subject entirely.

Claims about browser and platform behaviour

For example: "a Canvas element is opaque to screen readers" or "localStorage persists until the user clears site data". These are verified by testing in current browsers and by checking the behaviour against published web platform documentation. Where behaviour differs between browsers, we say so.

Judgements and recommendations

For example: "start with Cat Dash rather than Cat Obstacle Rush". These are opinions formed from play-testing and are labelled as such in the text. We do not present a judgement as a measurement.

How sources are evaluated

When an article needs an external reference, we prefer sources in this order:

1. Primary technical documentation for the platform in question - the specification or the browser vendor's own documentation.
2. Our own reproducible testing, described so that a reader can repeat it.
3. Established, widely-corroborated technical explanation where the underlying behaviour is not in dispute.

We do not cite content farms, aggregator sites, or articles that themselves cite nothing. If a claim can only be traced to a source of that kind, we treat it as unverified and leave it out.

What we will not do

• Publish a number we cannot trace to something real.
• Attribute a claim to "studies", "research" or "experts" without naming them.
• Present an estimate as a measurement.
• Describe a health, cognitive or educational benefit of playing games. These are claims that would require proper research, and we have not done any. Games on this site are presented as entertainment, which is what they are.
• Round a vague impression into a precise-sounding figure.

Keeping content current

Two things make content on this site go out of date. The first is a change to one of our games: if a mechanic changes, its page is inaccurate immediately, so game pages are updated as part of changing the game rather than afterwards. The second is a change in browser behaviour, which is slower and rarer; those claims are re-checked when we have reason to think something has shifted.

An updated date on a page means the content of the page changed. We do not refresh dates cosmetically.

How to report an error

1. Tell us what is wrongUse the contact page and choose "Correction request". Include the page and, if you can, the sentence.
2. Tell us whyA short explanation of what the correct position is, and how you know, makes verification much faster. For game behaviour, telling us what you did and what happened is enough.
3. We verify itClaims about our games are checked against the code. Claims about browser behaviour are re-tested. We do not simply take a report at face value, and we do not dismiss one either.
4. We correct and note itIf we were wrong, the page is corrected. A substantive correction - anything that changes the meaning - is noted on the page itself. A typo is fixed without a note.

Correction notices

A correction notice appears at the foot of the corrected page and states what was wrong, what it now says, and the date of the change. We do not quietly rewrite a claim and leave the page looking as though it always said the new thing.

Disagreements

If we look into a report and conclude the original text was correct, we will say so and explain why. Where something is a matter of judgement rather than fact - which game is the best starting point, whether a difficulty curve is fair - we may simply disagree, and in that case we will make clear in the text that it is a judgement.
