About the Game

Solar Smash is a sandbox simulation game that hands players godlike control over the cosmos. Built around realistic physics and an expansive set of tools for both creation and destruction, it sits in a space where scientific curiosity and pure chaos coexist. The game is structured around two modes, each offering a fundamentally different way to interact with the universe.
The first mode, Planet Smash, is centered on destruction at a planetary scale. Players choose a target, whether a familiar world from our own Solar System or a planet in an exotic star system, and then select from a roster of over 50 weapons to tear it apart. The variety on offer is one of the mode's strongest qualities:
Energy weapons: lasers, orbital ion cannons, railguns, laser swords
Explosive and nuclear options: nukes, antimatter missiles, supernovas
Alien and creature attacks: UFOs, space shibas, giant monsters, celestial beings
Military forces: battleships, space fighters
Gravitational tools: black holes
Defensive equipment: shields, defensive satellites
Beyond the standard planetary targets, Planet Smash also includes exotic environments featuring artificial megastructures such as ring worlds and enormous moons protected by planetary force fields, adding fresh challenges to the destruction.
Solar System Smash takes a completely different approach by focusing on simulation and experimentation. Players can choose from three pre-built star systems, one of which is our own Solar System, or build entirely custom systems from the ground up by placing stars, planets, and moons and defining their orbital paths. From there, the mode opens up into a physics sandbox where players can trigger planet-to-planet collisions, introduce black holes that pull objects off their courses, and observe how gravitational forces interact across an entire system over time. The behavior of objects follows realistic celestial mechanics, meaning the outcomes feel grounded even when things spiral into full cosmic disorder.
The physics simulation running beneath both modes is what gives Solar Smash its lasting appeal. Gravitational interactions behave consistently, destruction events produce cascading consequences, and the scale of events, from a single laser strike to a supernova, carries real visual and physical weight. Every action produces a reaction, and watching those chain reactions unfold is a core part of what makes the game engaging.
Controls are designed to be accessible without sacrificing depth. New players can start experimenting immediately, while more experienced players will find enough complexity in the physics and weapon interactions to stay engaged across extended sessions. The game does not gate its tools behind progression systems, which means the full scope of its sandbox is available whenever players want to explore it.
A content warning is included with the game regarding flashing lights, which may affect players with photosensitive epilepsy or related conditions.
