Smash Fest — Free Physics Destruction Game
Smash Fest is a free physics destruction game that runs right in your browser. A table on the beach is stacked with jam jars, tin cans, stone blocks, and wooden crates. Your cannon sits below, loaded and pointed at the pile. Fire, watch the structure collapse in a satisfying cascade of shattering jars and tumbling stones, and clear the table before your cannonballs run out.
The game has 50 handcrafted levels, works on phones and desktops, and needs no download, no account, and no install. Every level was designed by hand to have a clean solution — no randomly generated filler, no paywalled stages.
Why Smash Fest Is Different
Most browser physics games offer a sandbox with no goal, or a few throwaway levels. Smash Fest gives you 50 levels of real physics puzzles — each one hand-built, each one winnable in just a few well-placed shots. The physics engine runs at 60 frames per second, every collision is computed live, and nothing is pre-animated. When you fire a cannonball into a tower and watch it crumble, every piece moves according to its weight, shape, and the angle of impact.
What sets Smash Fest apart is the balance between skill and spectacle. You plan your shots like a puzzle game, but the payoff is a physics playground — jars shatter, stones tumble, and wooden beams tip over in real time. The game respects your time: no ads, no timers, no energy meters. Just you, a cannon, and a table that needs clearing.
How the Game Works
Press anywhere on the scene to take aim: a reticle locks onto the object under your finger or cursor. Drag to fine-tune the shot, then release to fire. The cannonball flies in a straight line to the exact point you picked — no arc, no drop, no guesswork.
Every level gives you a fixed number of cannonballs, shown at the bottom of the screen. Firing at empty air still spends a ball, so aim before you let go. When the balls run out and anything is left on the table, the level is failed — tap Retry and the level resets instantly with no penalty.
As you progress through the 50 levels, structures get taller, materials mix more often, and the number of cannonballs gets tighter. The early levels teach you the basics — later levels test whether you have actually learned them. There is no difficulty selector; the levels themselves are the curve.

Materials Cheat Sheet
Each material breaks by its own rule. Knowing them is the difference between clearing a level in two shots and wasting ten.
| Material | How it clears |
|---|---|
| Jam jar | Shatters the instant a cannonball touches it. The most fragile object in the game. |
| Tin can | Shrugs off direct hits. Knock it off the table — it clears when it lands on the sand. |
| Stone block | Heavy and stubborn. Breaks under a full-force direct hit, or when it falls to the ground. |
| Wooden crate & beam | Never shatters from a hit. Push it off the edge and let the fall do the work. |
One rule covers everything: any object that lands on the sand below the table is cleared. Gravity is your cheapest weapon.
Tips for Clearing Levels
- Shoot the supports, not the decorations. One ball into a load-bearing beam can bring a whole tower down.
- Let collapses finish before firing again. Falling objects clear themselves when they hit the sand.
- Save direct hits for stone. Jars and cans usually die in the chain reaction for free.
- Aim low on tall stacks. Removing the bottom layer sends everything above it over the edge.
- Count your cannonballs before the first shot. If a level gives you three balls and there are four stones, you need to kill at least one stone through gravity, not a direct hit.
- Edge shots are underrated. A cannonball that grazes the side of a crate spins it toward the table rim — sometimes a nudge is better than a head-on collision.

Frequently Asked Questions
Is Smash Fest really free?
Yes. The full game with all 50 levels is free to play in your browser. There are no in-app purchases, no premium levels, and no ads interrupting gameplay. You can play the entire game from start to finish without paying anything or creating an account.
Can I play Smash Fest on my phone?
Absolutely. The game works on any device with a modern browser — phones, tablets, laptops, and desktops. On mobile, press and drag to aim, release to fire. The interface adapts to your screen size and the physics engine runs smoothly even on mid-range devices.
How is Smash Fest different from other physics games?
Three things set it apart. First, the levels are hand-designed puzzles, not random sandbox arenas — every structure has weak points and every level has a tight cannonball budget. Second, the physics are full rigid-body simulation with realistic weight and collision response, not scripted animations. Third, the game loads fast and plays directly in your browser with no download, no account, and no ads.
How long does it take to finish all 50 levels?
Most players clear the first 20 levels in under 15 minutes. The full set of 50 takes anywhere from 45 minutes to a few hours depending on how carefully you plan each shot. Every level can be replayed — there is no time limit, and retrying a failed level is instant.
Does the game save my progress?
Your current level is saved automatically in your browser. Come back anytime and pick up where you left off — no login needed. Clearing your browser data resets progress, which is actually a feature if you want to replay the campaign from the beginning.
Play Free in Your Browser
Smash Fest is built with three.js for 3D rendering and the Rapier physics engine, a Rust-based rigid-body simulator compiled to WebAssembly. Every collision between a cannonball and a tower is computed frame by frame — jars shatter, stones topple, and wooden crates slide off the table ledge in real time. Nothing is scripted, so no two demolitions look the same. The whole game loads in under a megabyte and starts in seconds on a phone connection. No download, no install, no account — just visit the page and start firing.
The game is actively maintained with new levels, environmental themes, and gameplay features in active development. Curious about the project behind the game? See the about page for the tech stack and the full story.
