Galaxian

Stare down a relentless swarm of dive-bombing aliens, weave between their looping attacks, and keep your cannon blasting until the screen clears.

You know the drill: rows of bugs, one cannon, nobody coming to save you. Galaxian takes the Space Invaders formula and cranks up the chaos. Instead of sitting in neat rows, these aliens periodically break formation and swoop down at you in tight arcs, firing as they go. The first time a purple alien peels off and dives straight at your ship, you'll panic. After a few rounds, that panic turns into muscle memory — you learn to predict the dive angle and snap off a shot right as they reach the bottom of their loop. The scoring system rewards aggression. The yellow flagship aliens at the top are worth the most points, but they're also the ones that dive most often and with the sharpest curves. I kept coming back because every game feels like a high-speed puzzle: do you clear the edges first to reduce dive angles, or focus on the flagships and risk letting a column of regular aliens get too low? Your cannon has a short cooldown between shots, so spamming doesn't work. You have to place each shot deliberately — usually just ahead of an alien's dive path. It's an old game, but the tight hitboxes and pure reflex challenge still hold up. The sound of an alien exploding is a crisp little pop, and when you clear the last one and the formation resets, there's a split second of pure relief before the next wave starts. No upgrades, no continues, no mercy. Just you, your cannon, and a screen full of things that want you dead.

Use mouse or left and right arrows.

Focus on flagship aliens first — they're worth the most points and dive more aggressively. Keep moving sideways constantly; standing still is a death sentence when a purple alien commits to a dive. Time your shots for when an alien reaches the bottom of its loop — that's when they're slowest. Don't spam shots; the firing cooldown is short but real, so make each shot count. Memorize the formation: leftmost and rightmost columns dive first, so clear the edges early. If an alien is about to pass you, move the opposite direction at the last second — their dive paths are predictable.

Q: Is Galaxian free? A: Yes, it's completely free to play in your browser with no hidden fees. Q: Can I play Galaxian on mobile? A: It's playable in mobile browsers, though arrow-key controls are replaced by on-screen taps or mouse emulation, which is less precise. Q: Do I need to download anything? A: No downloads required. It runs instantly on any modern browser as an HTML5 game. Q: What's the best way to dodge diving aliens? A: Keep moving in small bursts, not all the way to one side.

A: Unlike Space Invaders, aliens break formation and dive at you, making it a faster, more reactive shooter. Q: Can I pause the game? A: Click outside the game window or press P; many HTML5 ports support pausing, though not all versions do.
