Play Gyruss Online

Summary

Gyruss feels like a cross between Galaga and Tempest, with my ship locked to the outer rim of an invisible circle while the stars rush outward from a vanishing point in the centre. The whole thing is set to an electrified version of Bach’s Toccata and Fugue, a synth‑driven track that instantly tells you you’re blasting through the solar system.

Each level represents a planet – Neptune, Uranus, Saturn, Jupiter, Mars and finally Earth – and you have to survive a series of warps before the next world appears. After every planet a Challenge Stage pops up, letting you rack up points by shredding as many enemies as possible. Double fire shows up when a sun‑like enemy with two blue pods appears; staying near the bottom of the screen makes that formation easier to hit. Asteroids can’t be destroyed, so you learn to dodge them, while bee‑like foes with force fields must be taken out to clear the way.

The cabinet was offered in both upright and cocktail versions, and the arcade board used two Z80 CPUs, a 6809, an 8039 microcontroller and five AY‑3‑8910 sound chips to deliver true stereo audio via discrete circuits.

A quirky high‑score bug freezes the displayed total at 999 990, and the only way to verify scores above a million is to add the 1‑up counter manually. Despite rumors, reaching Earth is possible – it happens on level 25 – and a handful of players like “KOO” and the Elliott Brothers were legendary in the ’90s.

Storyline

In Gyruss, the player’s mission starts with the message “2 WARPS TO NEPTUNE.” Each level brings the ship one warp closer to a planet, and after the ship reaches a world a brief bonus round lets you fire at enemy ships for points without risk of being destroyed.

The journey spans 25 stages of attack by the Ideoclan Empire, whose forces include Exarsions, Petarions, Terarions, Gigarions and, on bonus stages, Zigmas and Dogmas. After the Neptune segment the route continues with three‑warp legs to Uranus, Saturn, Jupiter, Mars and finally Earth, repeating the pattern.

Enemy fire is paused at stage 1 and every tenth stage when they first appear on screen. Once Earth’s bonus stage is cleared, the player must race through a fast “3 WARPS TO NEPTUNE” segment before the cycle begins again.
