About Solar Smash

Solar Smash is a planet simulator that lets you take it apart. What separates it from the countless destruction toys it inspired is the fidelity of the object being destroyed — this is a sphere with a crust, a mantle and a core, and weapons interact with those layers rather than with a flat surface. A laser that scores the surface and an impact that reaches the core produce genuinely different planets afterwards.

That layered model is why the aftermath is the interesting part. A struck planet does not vanish; the crust fractures along the impact, plates separate, molten interior becomes visible through the gaps, and debris either escapes into orbit or falls back over the following seconds. Watching that settle is the reward the game is built to deliver, and it is precisely what firing repeatedly prevents you from seeing.

The creation side is a separate program hiding behind the same menu. Building planetary systems and customising them gives you an object with your own decisions in it, and the difference between demolishing a default world and demolishing one you configured is larger than it sounds. Most people never open it, which is why most people describe the game as shorter than it is.

Sandbox and Casual are its categories. The scale is the thing worth calibrating on before you start — you are operating on planets and moons rather than on objects, and the game's whole proposition is that this is a scale nothing else lets you play with. It is a simulator you are allowed to break, which is a narrow and genuinely distinctive offer.

Tips for Solar Smash

  • Aim for different depths, not just different spots. Surface damage and core penetration produce completely different results on the same planet.
  • Wait for orbital debris to settle. What escapes and what falls back is decided in the seconds after impact, and that is the part worth watching.
  • Open the creation mode. A system you configured is a far better subject than the default planet you have already hit twenty times.
  • Rotate before firing rather than after. Where a weapon lands relative to existing damage changes how the crust breaks.
  • Combine weapons on one planet. Layered damage from two sources behaves differently from twice as much of one.
  • Compare a moon against a planet. Smaller bodies fracture in visibly different ways, and that contrast is free content.

Did you know?

  • The planet is modelled in layers — crust, mantle, core — so weapons that reach different depths produce structurally different outcomes.
  • After an impact the crust fractures along the strike and debris either enters orbit or falls back, which resolves over several seconds.
  • It includes a full planetary system creator alongside the destruction tools.
  • Moons and planets fracture differently because of their size, giving the same weapon distinct results depending on the target.
Comments
Quick FAQ
What makes the destruction worth watching?▼
The layers. The planet is modelled with a crust, a mantle and a core rather than as a painted sphere, so a weapon that scores the surface and one that punches to the centre leave structurally different worlds behind. That fidelity is what separates it from the flat destruction toys it inspired, and it is why the same weapon twice can look nothing alike.
Should I aim at a specific part of the planet?▼
Depth matters more than position. Hitting the same spot with a surface weapon and then a penetrating one gives you two different events, whereas hitting two different spots with the same weapon largely gives you the same one twice. Thinking about how deep a shot reaches is the most productive way to keep finding new results.
Why does the planet keep moving after I stop firing?▼
Because the aftermath is simulated. Fractured crust separates, the interior becomes exposed, and debris resolves into orbit or falls back over the following seconds. That settling is the payoff the game was built around — a struck planet is not a finished event, it is one that takes a while to conclude.
What does the creation mode offer?▼
A full planetary system builder, which most players never open. It matters because a world you configured yourself is a considerably more interesting subject than the default planet you have already hit twenty times. People who describe the game as short have usually only used half of it.
Do moons behave differently from planets?▼
Yes, and it is one of the easiest ways to get new results out of the same weapon. Smaller bodies fracture differently under the same force — less mass holding them together means a strike that would score a planet can dismantle a moon entirely. Comparing the two is free variety that costs nothing to try.
Is combining weapons worth doing?▼
It produces outcomes neither weapon manages alone. Damage from one source changes how the structure responds to the next, so a planet already fractured along one line behaves differently from an intact one. Layering two different weapons is more interesting than applying twice as much of a single one.
Does rotating the planet change anything?▼
It changes where a shot lands relative to damage already there, which is what actually varies the result. Rotating after firing is just repositioning the camera; rotating before firing is choosing whether to compound existing damage or open a new fracture. The second is a decision, the first is not.
What scale are we talking about?▼
Planets and moons, which is the game's actual distinguishing feature. Plenty of things let you destroy objects, vehicles or buildings; very few operate at the level of a world with an interior. Calibrating on that before you start is useful, because the pacing of everything — impacts, settling, debris — is slower than a human-scale toy.
Can I put a planet back together?▼
No, but you can build a new one. Destruction is one-way, and the creation mode is where you start again with something configured to your own specification. That separation between building and breaking is the structure the game offers instead of progression, and using both halves is what makes it last.
Do the weapons need earning?▼
No — every weapon and the creation tools are available from the first moment, with nothing to unlock. It runs in your browser on LemonArcade with no account and no download, and works identically on touch since the whole game is tap and drag. The site is funded by advertising rather than by charging for games.
