About AstroArcade

AstroArcade is a small, independent corner of the web built for people who love space: original browser games, practical solar-system calculators, and genuinely interesting space writing. Everything here runs instantly in your browser — no downloads, no installs, no accounts.

What you'll find here

• Astro Dodge — our flagship neon arcade game. Dodge, shoot and combo through endless asteroid waves. Your high score is saved on your own device.
• Weight on Other Planets calculator — a quick way to see what you'd weigh on Mars, Jupiter or the Moon, with the gravity math explained in plain language.
• Age on Other Planets calculator — your age in Mercury years, Mars years and beyond, plus your next "birthday" on every world.
• Space Trivia Quiz — ten random questions with instant scoring, drawn from a 30-question bank.
• The blog — game strategies, space science explainers and curated lists of the best free space games.

How it's made

Every game and tool on AstroArcade is hand-built with vanilla HTML5, CSS and JavaScript — all graphics are drawn in code and all sounds are synthesized in real time. Nothing is scraped, cloned or ripped from other sites, and no external game assets are used. The calculator data comes from public NASA planetary fact sheets.

How it's funded

AstroArcade is free to use. To keep the lights on, the site may display ads (for example via Google AdSense) — those help cover hosting costs so the games and tools can stay free for everyone. See our Privacy Policy for details on cookies and advertising.
