Brain Break Lab

It's the stretch after lunch, the class is wriggly, and you want a riddle or a quick movement break up on the screen right now. Brain Break Lab is a free site made for that moment, with riddles, movement breaks and simple games that go straight onto an elementary classroom screen, no accounts needed.

Its about page explains the gap it's meant to fill. Teachers already use riddles and movement breaks every day, it says, but most riddle pages are long lists with no grade levels and a lot of ads, which is hard to put on a projector in front of 25 kids. Its answer is one riddle per screen, with the answer hidden until you're ready, plus a timer and team scores.

The Riddle of the Day comes in two versions, for K–2 and for grades 3–5. Behind it are 360 riddles sorted by grade, each with a hint and a short explanation of why it works.

The movement breaks are This or That and Would You Rather. Kids answer a question like pancakes or waffles by moving, and there are 120 Would You Rather questions with a move for each choice. A brain break ideas page sorts quick activities by 1, 3 and 5 minutes. In November 2026 there were seasonal sets too, including 40 Thanksgiving riddles.

Games include tic tac toe for two teams, memory match and 2048.

The site is free for K–5 classrooms. The privacy policy, last updated October 14, 2026, says it doesn't ask for names, emails, photos or school names, and that there's no place on the site where a child could type them in. Page views are counted with Vercel Web Analytics, which the policy says uses no cookies and reports only totals.

There's one exception. Five games are made by independent developers and delivered by GameDistribution: Drift Boss, OvO and Stickman Duel, with Mahjong Connect and Tangram making up the rest. Nothing from that network loads until someone presses Play. Once a game starts, it may show a short ad and use cookies under GameDistribution's own policy.

The operator is named only as Brain Break Lab, with a contact email. If you'd rather avoid the ads and cookies, stay with the site's own games, and keep the riddle page handy for the next time your class needs a reset.
