Space Invaders
The fleet drops a row every time it touches the edge and moves quicker the fewer of them are left. Four shields take fire from both directions, including yours.
What Is the Space Invaders Trick?
Fifty aliens in five rows, a gun that slides along the bottom, and four shields that erode until they are useless. Clear a wave and the next one starts lower down and faster. The last two aliens move at a pace the first fifty never did.
Google has marked the game with doodles and themed results over the years, and standalone rebuilds like this one keep it a click away between anniversaries.
How Space Invaders Started
It was designed at Taito in 1978. The acceleration everyone remembers was a hardware limitation rather than a decision: with fewer aliens left to draw, the machine redrew them faster, and the difficulty curve that produced was good enough to keep.
That accident is why the game still works. Modern rebuilds copy the speed-up deliberately, in the same way the pac-man rebuild copies the ghost logic instead of simplifying it.
How to Play Space Invaders
- Press start, click the screen, then move with the left and right arrows.
- Space fires. Only a few shots travel at once, so aim before you tap.
- Clear the outside columns first to widen the space you can dodge in.
- Do not shoot through your own shields unless you have to. They do not repair mid-wave.
- Let the fleet reach the ground and the wave ends immediately.
FAQs
Why does the fleet speed up?
Fewer aliens means each is redrawn more often. The original hardware quirk is now a deliberate feature.
Can I play without a keyboard?
Yes. The three buttons under the board cover movement and firing.
Do the shields come back?
Only at the start of a new wave, never during one.
What else is worth playing here?
The brick wall in google block breaker and the runner in dinosaur game, plus everything else under google easter eggs.
