Choose your bomb
Every character runs the same 5-minute countdown to start. Meet Dynamite and the TNT Powder Keg below. Three bombs are free forever, and nine more are ready whenever you want the whole crew.
Other timer lengths
Looking for a dynamite timer or a TNT timer with a real burning fuse? This is it, cartoon-style: a stick of grinning dynamite, a wooden powder keg, and a fuse that sizzles its way down to a big, harmless boom. Everything is illustrated and kid-safe, with zero realism.
The countdown engine underneath is the same free timer that runs the whole site: pick any length from 30 seconds to an hour, project it on a smartboard or TV, and let the fuse do the nagging. Sound is opt-in, and a reduced-motion mode keeps things calm when you need it.
Best of all, the Dynamite character is free forever, so you can light this fuse right now with no sign-up. Want the wooden TNT Powder Keg too? A one-time $4.99 unlock adds it and eight more friends. Try a 5 minute countdown or a 1 minute lightning round to see the fuse in action.
