Real teacher use cases
Why review games work — and why teachers keep coming back to them.
Review games hit three things at once: spaced recall, group accountability, and engagement. A 20-minute Jeopardy round at the end of a unit consistently outperforms another lecture for retention — and students actually ask for it.
When to use a review game
Common spots in a unit where a 15–25 minute board pays off.
Manual builder vs AI generator — which to use
Both are first-class on Kleveroo. Pick by how much content is already written.
Use the manual builder when…
- You already have your review questions written
- Content is tightly tied to your specific lesson
- You want full control over wording and difficulty
- You're on the free plan
- You enjoy writing the clues — that's the prep
Use the AI generator (Plus) when…
- You have a topic but no clues written yet
- You want to paste a PDF lesson plan and get a draft
- You make multiple review boards a week
- You're fine editing AI output before class
- You're prepping a sub plan in a hurry

What a review board looks like on the projector
Five categories down, six rows of point values across. Click a tile to reveal a clue, run the timer, then award points to the team that answers first. Designed for projectors, TVs, and Chromebooks.
Inside a clue — timer, reveal, points
Each tile opens a full-screen clue with a built-in countdown timer. Press space to reveal the answer, then tap +/− on the team scoreboard. Hotkeys keep the pace up so review week stays sharp.

Frequently asked questions
+What are review games for teachers?
Review games are short, structured classroom activities that re-surface what students learned in a unit. The Jeopardy-style format is popular because it groups content by category, scales by difficulty, and turns recall into a low-stakes competition between teams.
+Are Kleveroo's review games really free for teachers?
Yes. Building and hosting manual boards is free forever, with no trial timer and no credit card. Paid plans only add optional extras like AI generation, premium curated boards, larger 8×8 boards, and visual themes.
+How long does it take to build a review board?
A manual 5×5 board (5 categories × 5 clues) typically takes 15–25 minutes if you already have the content. With the optional AI generator (Plus), you can paste a topic or a PDF lesson plan and get a playable draft in under a minute, then edit anything you want to change.
+What grade levels does this work for?
Kleveroo is used by elementary, middle school, high school, and college instructors. The format is flexible: simpler clues and smaller boards for younger students, denser clues and 8×8 boards (Plus) for AP, college, and test prep.
+How do students play — on their own devices or one shared screen?
Both work. The most common classroom flow is one shared screen (projector or TV) with the teacher hosting and students grouped into teams. There's also a remote/hybrid mode where students join from their own devices.
+Can I save and reuse boards year after year?
Yes. Boards are saved to your account. You can duplicate, edit, and re-host them every semester. Many teachers maintain a library of boards by unit so review week is just 'open last year's board.'
+Is there a library of pre-built review games I can use right away?
Yes. Kleveroo has a growing library of free community boards plus curated subject sets for teachers (science, math, history, ELA, Spanish, French, Italian, vocabulary, test prep, computer science, and more). You can play them as-is or remix them.
