Star Trigon is a series of video games developed by Namco. Star Trigon puts the player in the role of a spaceperson spinning around a planet, having to rescue the stranded aliens in time before his air supply runs out. Games in this series have been released for iPod, Windows, and iPhone in addition to the arcade versions.
In Star Trigon, after a character and stage is selected the player has to rescue stranded aliens from aimlessly drifting through outer space by hopping from planet to planet to form triangles, the alien is saved if the player manages to contain a drifting alien within a triangle. The player will be awarded in-game pickups to increase score and air packets to increase air supply. Star Trigon is simple in only requiring one button, the challenge is timing the jumps from planet to planet and rescuing the stranded aliens before the air supply is depleted and as your characters are spinning faster and faster without jumping off screen. Along the way new obstacles will help complicate things and add to the challenge of the game like black holes and flares.
Each character is unique in the amount of air supply, speed and acceleration.
- Wataru: Adequate air supply, lowest speed and high acceleration.
- Susumu: Lowest air supply, moderate speed and slowest acceleration.
- Chuta: Largest air supply, slow initial speed but with highest acceleration.
