Space Crash Simulator vs Earth Sandbox
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
Space Crash Simulator
Experience realistic planetary collisions with a powerful physics engine. Customize your own cosmic events by adjusting particle count, velocity, and accuracy, or jump straight into high-energy impacts. This app offers a detailed, physics-based simulation for educational or entertainment purposes.
- Smoothed Particle Hydrodynamics (SPH) simulation
- Real-time planetary collisions
- Customizable simulation parameters
- Setup Mode for scenario creation
- Adjustable particle count and accuracy
- Physics-based detailed simulation

Smash worlds together and watch them shatter, merge, and melt, driven by real physics, not pre-made animations. Every planet is made of thousands of interacting particles, so every collision is computed live and no two impacts ever look the same. Build your own scenario in Setup Mode: place up to 8 bodies, set their size, density, spin and velocity, then let gravity do the rest. Or dive straight into a head-on collision and watch the debris glow, cool, and form a crust. - True particle physics (SPH), the first of its kind on mobile - Molten impact zones: heat, lava, and cooling crusts - Give planets rings or shred a moon into one with tidal forces (Roche limit) - Protoplanetary disk and colliding-galaxies modes - Black holes that tear planets apart - Custom planet textures from your own photos - Runs on everything: tune particle count, accuracy, and timescale to your device
Earth Sandbox
Explore the dynamic evolution of a planet by altering its core systems like climate and gravity. Trigger natural events and observe real-time population and ecosystem trends. This experimental simulation game offers unique outcomes with every interaction.
- Earth-focused environmental simulation
- Interconnected climate and planetary systems
- Dynamic natural events
- Real-time population and ecosystem trends
- Interactive experimentation tools
- Clean visuals and intuitive controls

Earth Sandbox is an experimental simulation game centered on Earth itself. Instead of following a fixed story or objective, the game invites you to explore how a planet reacts when its core systems are changed. Climate, gravity, oceans, and atmosphere interact dynamically, creating unique outcomes every time you experiment. You can adjust environmental conditions, trigger natural events, or push the planet into extreme states. Rising temperatures may reshape ecosystems, shifting gravity alters planetary balance, and sudden disasters can permanently change the world you observe. Natural events such as meteor impacts, earthquakes, volcanic activity, and global climate shifts are part of the simulation. Each event influences the planet differently depending on existing conditions, encouraging experimentation rather than repetition. The simulation is driven by interconnected systems inspired by scientific principles. Population trends, environmental stability, and planetary conditions evolve in real time, allowing you to observe long-term consequences of your actions. Features: • Earth-focused environmental simulation • Interconnected climate and planetary systems • Dynamic natural events and long-term world changes • Real-time population and ecosystem trends • Interactive tools designed for experimentation • Clean visuals with intuitive controls How will your choices shape the future of this Earth?

Verdict
The clearest difference is rating: Space Crash Simulator at 4.5 against Earth Sandbox's 4.0. Space Crash Simulator also leads on review sentiment (82% vs 50%) and ratings volume (593 vs 2). Earth Sandbox's advantage is in-app purchases (none vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Space Crash Simulator sells 1 one-off in-app purchase. Earth Sandbox asks for nothing beyond the download.
Space Crash Simulator holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Space Crash Simulator has 593 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 82% of Space Crash Simulator's written reviews are positive against 50% of Earth Sandbox's.
Space Crash Simulator ships an update every 4 days, Earth Sandbox weekly. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
