Rubble in short
- Eight voxel buildings, from a garden shed to a glass tower.
- Three tools: cannonballs, charges and a wrecking ball.
- Each level gives you a few of each, and up to three stars.
- A sandbox mode with unlimited tools and no score.
Why a demolition toy
Breaking things is one of the oldest pleasures in block games. Every Minecraft player has dug the floor out from under a friend's house at least once, and Teardown built a whole game around the idea that every wall can come apart. Rubble is a much smaller take on the same feeling: a building made of loose blocks, a handful of tools and a short puzzle about where to hit it.
Nothing in Rubble is scripted. Each block is a separate physics body with its own weight, so a building falls the way it was built. Knock out the right support and the floor above comes down with it. Hit the wrong spot and you just chip a corner.
How to play
Press Play and you start on the first building. Pick a tool from the bar at the bottom, then tap or click the building where you want to use it. Drag to turn the camera, and pinch or scroll to zoom.
The bar at the top shows how much of the building is down, with a tick for each star target. When your tools run out and the dust settles, the level ends and you get your stars. If you'd rather stop early, press Finish.
The three tools
| Tool | How it works | Good for |
|---|---|---|
| Cannonball | Fired from the camera at the spot you tap | Knocking out low walls and supports |
| Charge | Stuck to a block, then set off with Detonate | Removing load-bearing blocks |
| Wrecking ball | Swings on a chain through the spot you tap | Tall, top-heavy buildings |
Charges are the most useful tool and the easiest to waste. Place them all first, then press Detonate once. A charge destroys the block it's stuck to and anything touching it, then throws the blocks around it outward. Charges placed close together on the same wall do far more than charges spread out.
The eight buildings
The levels unlock in order. Earn one star on a building to open the next one.
| Level | Building | Tools |
|---|---|---|
| 1 | Garden Shed | 3 cannonballs |
| 2 | Stone Tower | 2 cannonballs |
| 3 | Village Gate | 2 cannonballs, 2 charges |
| 4 | Farmhouse | 3 cannonballs, 3 charges |
| 5 | Watchtower | 2 cannonballs, 1 wrecking ball |
| 6 | Toll Bridge | 2 cannonballs, 2 charges |
| 7 | Castle Keep | 3 cannonballs, 4 charges, 1 wrecking ball |
| 8 | Glass Tower | 2 charges, 2 wrecking balls |
The star targets get lower as the buildings get bigger. Taking down a third of the castle is a decent result, while the shed expects you to flatten nearly all of it. In the Glass Tower, a fast wrecking ball shatters any glass it passes through.
Sandbox mode
Open Levels and you'll find the sandbox under the level list. Pick any of the eight buildings and you get unlimited tools and no score, which is the best way to try ideas before you go back for three stars. Every building is available in the sandbox from the start.
Keyboard controls
- 1, 2, 3 pick the cannonball, charge or wrecking ball.
- Space or Enter uses the tool at the centre of the view.
- D sets off placed charges.
- R resets the building.
Tips for three stars
- Aim low. Most buildings fall from the bottom up. A cannonball at the base of a wall does more than one at the top.
- Find what holds the weight. Corner posts, legs and the blocks under a heavy roof are worth more than anything else.
- Group your charges. Two charges side by side open a gap that the building above can fall into.
- Use the drop. On the Toll Bridge, anything that falls into the gap counts, so the deck is the prize.
- Turn the camera. The best angle is often not the one you start with. Look for the side where a hit will tip the building toward open ground.
Privacy and saving
Rubble needs no account. Your stars, best scores and sound setting are stored in your browser's local storage on the device you play on, and the game sends nothing to a server. The physics runs on Rapier, an open-source physics engine, entirely on your own device.
If you liked Rubble, our other game is Daily Knap, a one-minute daily puzzle. Or go straight back and knock something down.
Frequently asked questions
Is Rubble free?
Yes. It runs in your browser with no account, no download and no ads inside the game.
Does it work on phones?
Yes. Tap to use a tool and drag to turn the camera. A recent phone or tablet works best, because every block is simulated with real physics.
How are stars worked out?
Each building has three targets for how much of it you knock down. Pass the first target for one star, the second for two and the third for three.
What counts as knocked down?
A block counts once it has dropped, slid well away from where it started or tipped over. Blocks destroyed by a charge count too.
Where is my progress saved?
In your browser on the device you play on. Clearing site data or switching devices starts your stars again.
