More or Less Games for Kids
10 tested
This is a genuinely separate genre that happens to share a name. These are counting and quantity games for children roughly aged three to eight, not trivia. Entries record the age range, whether an account is required, and whether the activity works on a classroom whiteboard.

Games
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
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.
No datasetClassroom
ABCya
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 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.
