Original content
- Games. Every game on Game Utsav was written from scratch for Game Utsav. Each game is named "Game Utsav" plus a plain description of its genre, for example Game Utsav Snake, Game Utsav Grand Prix and Game Utsav Robot Arena. Genre words like "snake", "grand prix" or "brick breaker" are everyday descriptions that no one owns, and the game mechanics are common genres. The name Game Utsav is our own brand; "utsav" is a Hindi word for festival.
- Sports and military games. Game Utsav Cricket and Game Utsav Football use invented teams ("Challengers XI", "Rivals") with plain colours - no real leagues, tournaments, clubs, players, kits or logos. The tank, naval and jet games use generic, made-up vehicles and unmanned robot opponents rather than any real manufacturer's design or real armed forces.
- Graphics. All graphics, including cars, robots, tracks, tiles, icons and textures, are drawn by our own code at run time. Game Utsav uses no image files, sprite sheets, 3D model files or stock art.
- Sound effects and music. Every sound effect and every piece of music is synthesised live in your browser by Game Utsav's own code, using the Web Audio API. The melodies are original compositions generated from our own note data. There are no audio files, samples or third-party recordings.
- Fonts. Text uses your device's built-in system font. No web fonts are downloaded.
