Push one building and watch the whole street come crashing down. The Puppy Busters are here to clear the District!

Buildings line a long street, Block after Block. Hit one and it falls into the next, which falls into the next. The longer the Chain, the more Gold you earn—up to 2.5×.

Your job is to choose the first Domino. Tap a building to mark it for Blast and see arrows above the rooftops predicting how far the Chain will go. Or sit back and watch: the dogs keep pushing down the street on their own.

The three dogs from the Demolition Truck each have a role. Front pushes buildings from the roadside so they hit their neighbors harder. Flank pierces several buildings at once from an alley. Finisher topples any building it hits to the east to keep the Chain going. Tap a dog on the Truck platform to make that dog stronger, or tap Cargo to earn more Gold.

Every Domino Chain fills the Hype meter. Fill it, and all three dogs race ahead with speed lines for 12 seconds of Frenzy. There's nothing to buy or switch on: the better your Chains, the more often it happens.

Clear a Block and the dogs cross to the next one. The street continues without a stop screen, leaving empty lots behind. At the end of each District stands its own Landmark: a city hall clock tower, a market water tower, a factory chimney… Wear it down with Chains, then topple it across the street to stamp the District complete. Named Districts such as Cherry Blossom District, Market Alley, and Ironworks District keep coming, with no time limit.

The dogs carry Demolition Tools: a nail gun, long drill, giant hammer, fire hose, wrecking ball, and Blast stick. Each of the six families topples buildings differently and grows through 14 Tiers. Merge two Tools of the same Tier to make the next one. The new Tool takes the family of the spot where you drop it, so you can choose which family to build. The first Tool you get from each family goes on the Collected Tools board.

There are 42 Breeds, including Jindos, Shibas, Corgis, and Huskies. Put the Breeds you've brought home in the Front, Flank, and Finisher positions, and give them names you like.

Want a break from the Street? Open the job board on the Challenge tab.
Domino Shot is a puzzle where you throw Blast sticks to the left or right of a building to topple a whole row. Each of the first six stages teaches something different, including toppling from high to low, fuses that carry fire to another row, steel-frame buildings a Chain can't cross, and buildings that need one hit from each side. Use fewer sticks to earn more stars.
In Demolition Job, topple only the taped job buildings while protecting the blue-roofed neighbor's house. Tap a red arrow to change which way a building will fall. The dogs wait in front of red-arrow buildings while you decide.
In Giant Robot Tower, tap all three glowing weak floors to break them, and the robot falls sideways with a boom.
Jobs and robots start at a level matched to your current Street progress. Challenge rewards give Gold equal to a few minutes of your current Street earnings. Your Block is remembered, so you can pick up where you left off when you return.

The dogs keep working for up to 2 hours while the app is closed. When you reopen it, you'll see their Work Log. The game works without internet, and progress is saved on this device.

Ads are optional rewarded ads only. They appear only when you tap a “Watch an ad …” button in the Work Log, Challenge, or Shop. Skip them and you still get what you would normally receive.

In-app purchases include Gems, Breed Tickets, and Gear Crates. You can check the odds for randomized items before buying.
