Plenty of games in this genre technically load on a phone and are still unplayable there — cut-off images, buttons under the fold, text at four pixels. Mobile behaviour on every entry is recorded from an actual phone-sized viewport, not from a media query.

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.
OSRS Tools

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one puzzle a day and no advertising — the tightest daily format in the directory, on a dataset that can never go out of date.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.
moreorlessgame.co.uk

Built as a probability exercise first and a game second. It shows the whole suit with Ace at one and King at thirteen before you start, which no other card entry bothers to do.
Transum

The only kids' entry here that covers equal to alongside more and less, and reads its questions aloud — which is what a pre-reader actually needs.
ABCya

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

One of the few modes anywhere that prints its refresh month next to the rules — March 2026 — which makes it the best-documented film comparison game we have tested.
HigherOrLowerGame.com

Publishes its March 2026 refresh month, which matters more here than for box office — ratings drift both ways, so a snapshot can be wrong rather than merely incomplete.
HigherOrLowerGame.com

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 clearly aimed 4-to-7 comparison game using everyday objects rather than abstract numbers, wrapped in more sign-up and ad-free upselling than the activity warrants.
Kids Academy

The endless-streak counterpart to the daily version: same immovable dataset, no round limit, an explanation of what BST means, and five advertising networks.
HigherOrLowerGame.com

The only Pokémon entry that publishes its exact pool — 649 items, generations one to five, 180 to 720 — which is admirable, and also a warning that four generations are missing.
MoreOrLess.io

The youngest-targeted activity in this directory at ages 2 to 5, made by a teacher and played over 104,000 times — but it has not been touched in seven years.
TinyTap

Designed for a projector rather than a phone, with a dedicated full-screen mode and a classroom toolset around it — undermined by the heaviest ad load in this category.
Online Stopwatch

A well-built early-years comparison activity inside a paid curriculum, which makes it a reasonable choice for a subscribing family and the wrong one for a classroom needing something open.
ABCmouse

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.
higherlowercardgame.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

The ad-free way to play this exact game. It shares its leaderboard, and therefore its backend, with a sister site that loads eight advertising networks.
FootballMinigames

The same comparison as the market leader with no advertising at all and the exact rating shown on screen — but it is the one that does not publish a refresh date.
PlayHigherLower

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.
11Inicial

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.
GeographyGames

The only football entry here that names its data source. It says Transfermarkt on the page, adds World Cup and Premier League pools — and loads eight advertising networks.
HigherOrLowerGame.com

Names Rightmove as its source and carries a proper non-affiliation notice, but publishes no date for prices that move every month — and loads six ad networks doing it.
HigherOrLowerGame.com

Identical to the FootballMinigames version down to the shared leaderboard, but with eight advertising networks attached. There is no reason to choose this one.
Football Games

The most complete free platform in the genre: daily, versus and a custom builder in one place, with no ad networks loading at all — a combination nothing else we tested matches.
playhigherlower.com

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.
higherorlower.org

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 more game-like take on the format, with career progression and a hall of fame layered on top — but it publishes almost no readable content, so you have to launch it to learn anything at all.
moreorless.io

The broadest catalogue in the genre by some distance, and the obvious first stop if you want variety — but it carries the heaviest ad load we measured and mixes an adult category in with the rest.
higherorlowergame.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.
