🏗️ Demolition Simulator

Bring the house down (the fun way)

Demolition Simulator puts you in charge of a demolition site. A building stands in the middle of a fenced-off yard, a big yellow tower crane waits beside it and a blue site cabin sits in the corner. Your job is to knock the building down. Every wall, pillar, floor and roof is built from real physics blocks, so when you take out the bottom of a wall the bricks above really drop, tip and tumble across the dirt, with clouds of dust and a good shake of the camera.

It's the kind of satisfying destruction that kids love to watch, with none of the scary parts: there are no people inside, nobody gets hurt and everything is made of chunky cartoon bricks and blocks.

Three demolition tools

Demolition charges are the careful choice. Click blocks to stick red charges on them (up to eight at once), then press Kaboom! and they all go off together, blasting nearby blocks outward and upward. A charge at the base of a tower does far more than one near the top, so it pays to think about where the weight is.

The cannon is quick and cheap. Click anywhere on the building and a heavy iron ball flies from where you're standing straight at that spot. One ball can knock a hole in a wall; a few well-aimed shots at the corners can bring a whole side down. Walk round the site to find a better angle.

The wrecking ball is the big one. Turn the crane with one slider, set how low the ball hangs with the other, then press Swing! and a five-tonne ball on a chain swings through whatever is in its way. Set it low for walls and higher for towers: one good swing can take out a whole side of a building.

Nine jobs, from a garden wall to a skyscraper

The jobs get bigger as you go. Start with a simple brick garden wall and a tall, thin old chimney, then a wooden garden shed with a tin roof. Next come a stone castle keep with four corner towers, a water tower on four legs with a blue tank on top, and a step pyramid of golden blocks. The last three are the toughest: a five-storey concrete office block, a giant robot statue and a ten-storey glass skyscraper. The office block and the skyscraper stand on busy city streets with no room for the crane, so you have to bring them down with charges and the cannon alone: find the pillars that hold up each floor.

Each job asks you to knock down a set share of the building, shown as a white line on the progress bar. Every tool costs money, so the real challenge is to do it cheaply: finish at or under the par cost for three stars, within one and a half times par for two, and any finish for one. Finishing a job unlocks the next.

Free Play: unlimited tools

Free Play drops four buildings onto the site at once: a brick wall, a stone tower, a shed and a small pyramid, and every tool is free. Line up the crane, plant a row of charges or fire the cannon until nothing is left standing. It's a great place to try ideas before a real job, or just to enjoy the crash.

Physics that teaches a little engineering

Because every block is simulated, Demolition Simulator quietly shows how buildings stand up. Take out a pillar and the floor above it sags and slides; knock the bottom row out of a wall and the rest follows; hit a tall tower low and it topples, hit it high and only the top falls off. Children soon learn to look for the load-bearing parts, which is exactly how real demolition engineers plan a job.
