Play Sinistar Online

Summary

Playing Sinistar feels like a frantic space‑mining sprint. I pilot a tiny triangular fighter, blasting planetoids until they shake loose glowing crystals, then scoop those crystals into my bomb bay to forge "Sinibombs" – the only ammo that can tear the skull‑faced boss apart. While I’m busy mining, red Worker ships race to steal the crystals and assemble the Sinistar piece by piece, and gray Warrior ships dart in to fire at me, forcing me to weave rather than outrun them.

Each zone has its own flavor: the Worker Zone swarms with crystal‑thieving reds, the Warrior Zone fills the screen with aggressive grays, the Planetoid Zone offers abundant rocks to mine, and the Void Zone is a barren nightmare with barely any planetoids. After 13 successful Sinibomb hits the fully formed Sinistar collapses, its digitized voice snarls “Beware, I live!” before it tries to eat my ship.

The cabinet’s 49‑way optical joystick and the iconic roar – a stock gorilla growl – give the game a tactile, almost cinematic feel. A quirky bug can wrap my lives around to 255, turning a near‑death into an absurd extra chance. Originally slated to be called "DarkStar," the final product became the notoriously hard, speech‑laden classic we still hear echoed in arcade lore.

Storyline

In Sinistar, the player pilots a lone triangular fighter ship through a series of zones—Worker, Warrior, Planetoid, and Void—displayed on a mini‑map at the top of the screen. By shooting drifting planetoids the ship releases white crystals that can be collected; these crystals are used to create Sinibombs, the only weapon capable of destroying the end‑of‑level boss. Red enemy worker ships race to gather the same crystals while Warrior ships both mine crystals and guard the construction site, attacking the player whenever they get too close. When enough crystals have been amassed, the workers assemble the massive red‑and‑silver Sinistar, a demonic skull‑faced spacecraft that springs to life and begins chasing the player. Its digitized voice taunts with lines such as “Beware, I live!,” “Run, Run, Run!,” and “I am Sinistar!”; the boss has no weapons but destroys the player on contact, forcing the pilot to launch a Sinibomb that automatically homes in on the creature.
