Thirty seconds is pure adrenaline. This free 30 second bomb timer is built for quiz questions, speed rounds, lightning votes, and one-at-a-time turns in party games. The fuse burns fast, so nobody has time to get bored, including the kid who answers first.
In class, thirty seconds is the classic per-question think time: read the question, start the fuse, answers up when it blows. Our quiz timer is tuned exactly for that, with 15, 30, 45, and 60 second presets one tap apart.
It also makes a great turn timer for board games where someone (no names) takes forever to move. Need a touch more time? The 1 minute bomb timer doubles the runway, and the +30s button stretches any round on the fly.
Working with a longer block of time? The 1 hour bomb timer gives you the full sixty minutes with the same cartoon fuse.
Teaching a class? The classroom timer runs the same bombs on the smartboard, with no ads on the page.
