The only entry in this directory that earns the Live Data label. It reads Grand Exchange prices from the wiki API at play time, so a round today reflects today's market.

A sign-up wall is the fastest way to lose a casual player, and it makes a game unusable in a classroom. Every entry on this page was opened in a clean browser session and played through at least one full round without an account.
Independent directory. Not affiliated with the games listed.
Games
Ten rounds, two mistakes, one puzzle a day and no advertising — the tightest daily format in the directory, on a dataset that can never go out of date.

Pokédle
Three genuinely different ten-round games rather than one dataset dressed three ways, with a stated data period, no ads and no sign-in — the most complete property entry here.

Property Investments UK
Nine comparison metrics, a generation range filter and a fully-evolved-only toggle make this the most configurable Pokémon game here, with no ads and a public repository.

Full Life Games
The strongest classroom entry in this category: number ranges can be controlled by the teacher, an optional number line supports children who need it, and no account is involved.

Topmarks
Adds betting to the card version and then removes the easy wins, skipping extreme cards after each bet — a small rule change that turns it into a real probability lesson.

Math is Fun
The boxed version of this whole genre, and the reason the disclaimer at the top of our pages exists — it is a separate company with a nearly identical name.

The pure form of the game: a real deck, no trivia, no dataset, no ads. Card counting actually works here, which makes it the only entry rewarding a genuine strategy.

BrainBashers
Adds a speed element to group comparison, and pairs the game with worksheets and videos on the same topic — useful for a teacher who needs more than one activity.

Math Game Time
A competent card simulator that loaded no ad networks, but the page is mostly a portal — the game is one tile among dozens competing for the same click.

SilverGames
Two buttons and a card, with no advertising and nothing else whatsoever. Admirably direct, and so minimal that the page tells you almost nothing before you click.

Not playable at the time of checking. PrimaryGames states the game is unavailable while Flash content is migrated to emulation, and lists it as a known gap.

PrimaryGames
The only game in this first batch that prints its data capture date on screen before you play, and it does it with no ads and four difficulty tiers. The mobile layout is the weak point.

animehol.com
A single-topic game that does the important thing right: it prints its data month on the page, next to the start button, where you cannot miss it before playing.

HiLoMC
Uses official HM Land Registry sold prices rather than asking prices, and shows the sale year — so it is testing historical price sense, not this month's market.

House Price Guessr
Shows you the full property — beds, baths, type, floor area, exact address — before asking, which makes it a fairer test of property sense than any other entry here.

Guess The Party
Four languages, a daily challenge and a visible changelog showing active maintenance — the most obviously alive football entry here, though its data source is still unnamed.

The rare geography game that ships all three formats — endless, head-to-head and a shared daily — and explains its rules before you start. The ad load is the price you pay.

Gone. The domain now serves a registrar parking page with no game behind it, so any link or recommendation pointing here is out of date.

Smaller than the big platforms and better for it: eleven categories, each of which tells you the exact question it will ask before you commit, in eight languages.

The original, and still the cleanest expression of the format — but it has never published a date for the search volumes it runs on, which is now the main thing standing between it and a recommendation.

higherlowergame.com
A general puzzle portal that happens to own the plural domain, rather than a comparison-game specialist — the higher or lower titles are a section, not the subject.

higherorlowergames.com
Technically a decent ad-free platform with a wide mode list, but adult categories lead the catalogue on the home page, which rules it out for anyone browsing with children nearby.
