Roll down a street covered in stuff and flatten all of it.
Every thing crunches its own way, right as the drum goes over it. A game for Android with no ads and no account.
It's all about the crunch
There are 41 things to flatten, and none of them break the same way. The sound is made the moment the drum touches it, so it always lands in time.
- Bubble wrapPops bubble by bubble as the drum rolls across it.
- Window paneCracks in a spreading web, then shatters.
- Corn on the cobEvery kernel pops like popcorn.
- Toy pianoPlays its keys as you crush them.
- String of firecrackersGoes off one after another down the line.
- PumpkinThe stem snaps, then a hollow thunk and a squish.
- Sparkling ciderThe cork pops, the bottle shatters, then it fizzes.
- Glow sticksA bright little snap, one stick at a time.

What's in it
A new road every day
The Daily Challenge is one road, the same for everyone. Post your score to the daily leaderboard on Google Play Games and keep your streak going.
Streets for every season
Main Street, the Boardwalk and Office Park, plus holiday streets that open for a few weeks a year: Halloween, Thanksgiving, Christmas, New Year's Eve, Valentine's Day and the Fourth of July.
A garage to fill
Earn 13 more rollers and 9 more horns by playing, from a fire engine and an ice cream truck to a train horn and sleigh bells.
Missions and a collection book
Three new missions a day, and a book of everything you've flattened. Tap anything in it to hear it get crushed again.
Power-ups
Roll over them for a wider drum, a magnet that pulls things under you, double points or slow motion.
Share your best moment
One tap turns the best 12 seconds of a run into a video, sound and all. It's made on your phone and goes only where you send it.
Made to be played your way
Sound captions, steady lights, no screen shake, bigger text, gentler steering, a horn button on either side and a slower game speed.
Two ways to roll
Smash Run gives you 75 seconds that keep getting faster. Zen Roll has no timer and calmer music.
Free to play, packs if you want them
