Solar Smash

Phone / tablet

The usual touch scheme: pick a weapon, tap the planet where you want it to hit, and drag to turn the planet.

Desktop

Same idea with a mouse: click to fire, click and drag to rotate the planet.

Modes

The App Store listing describes two: Planet Smash, where you throw weapons at a single planet, and Solar System Smash, where you set up a star system with its orbits and let it run.

Levels

None. There is no level list and no ending; you pick a target and play.

Progress

There is no run to protect, and whatever the game keeps is saved the way YouTube Playables saves it, tied to your YouTube account.

The good part is the second shot: the same weapon on already-cracked ground behaves differently, so build up damage instead of spamming the biggest thing.

1. Rotate before you fire. Most weapons land where you aim, so spin the planet and hit the far side too. A globe cracked from two directions comes apart in a way one-sided damage never does.
2. Build damage in layers. Meteors to crack the crust, then a laser or a nuke into the crack. Piling one weapon on a fresh wound does more than the same weapon on an untouched surface.
3. Wait for the debris. The show is in the seconds after the hit, when the pieces drift and the glow spreads. Firing again right away just hides it.
4. Try the star-system mode on desktop. Placing planets and nudging orbits wants a mouse; on a phone I kept grabbing the wrong thing. Set an orbit slightly off, then sit back and watch the collision come.
5. Reset often. A fresh planet costs nothing, and half the fun is testing one weapon at a time. Reset, try something else, compare.

This version runs inside youtube.com, so it usually opens where game sites are filtered: at school or on a work network, if YouTube loads, Solar Smash loads with it. There is no separate site, no proxy and no unblocked mirror to trust, which is a better deal than most of the 'unblocked' copies floating around. If YouTube itself is blocked, nothing helps, and I wouldn't go looking for a mirror that claims otherwise. The one practical tip: give it a minute on a slow connection before deciding it's broken. The planet takes a moment to load, and so does the first big explosion.

This is the original Solar Smash from Paradyme Games, on the App Store since January 2020 and sitting at 4.8 stars there from close to 400,000 ratings. What runs inside YouTube is that game in a browser tab: nothing to download, no mod APK, no streaming service in the middle. The 'Solar Smash 2D' that turns up on browser game sites is a flat, simpler take on the idea, not this game, and now.gg runs the mobile app in the cloud; this is the more direct door.

One caveat: I can't promise every weapon and achievement from the mobile listing made the trip. Treat the YouTube version as the core sandbox and you won't be disappointed.

If you've seen Universe Sandbox on Steam, you know the serious end of this idea: real masses, real orbital math, a physics lesson you can break. Solar Smash is the toy end. It gives you the same pleasure of watching a planet come apart, but with weapons instead of a spreadsheet, and it loads in a browser tab in seconds rather than needing a proper PC. The star-system mode gets closest to Universe Sandbox: place planets, set orbits, throw in a black hole and see what unravels. It is shallower and it knows it. For a two-minute break, that's the right call; for a rabbit hole, Universe Sandbox wins.
