# Fun Circle Games > Fun Circle Games (funcirclegames.com) is a free, browser-based creator studio for making music-synced bouncing-ball videos and other satisfying physics simulations for TikTok, Instagram Reels, and YouTube Shorts. Import any song or MIDI file and every bounce triggers the next note in perfect sync, then export 4K no-watermark video. Fun Circle Games turns music into viral "bouncing ball" videos. It runs entirely in the browser (no install) and exposes 1,000+ editable physics parameters for precise control over motion and sound. A free tier is available; the Pro Creator and Studio Elite plans add commercial rights, no watermark, and advanced tools. ## Simulation modes - [Rhythmic / Music Sync](https://funcirclegames.com/modes/rhythmic): a bouncing ball plays a song or MIDI file, one note per bounce - [Spawner](https://funcirclegames.com/modes/spawner): classic physics-driven ball spawning - [Escape](https://funcirclegames.com/modes/escape): breakout-style concentric-ring timing challenges - [Breaker](https://funcirclegames.com/modes/breaker): destruction and brick-break physics - [Drawer](https://funcirclegames.com/modes/drawer): geometric trails and artistic patterns - [Trail](https://funcirclegames.com/modes/trail): glowing neon light trails and motion flows - [Ghost Escape](https://funcirclegames.com/modes/ghost-escape) and [Spiral](https://funcirclegames.com/modes/spiral): additional physics variants ## Key pages - [All simulation modes](https://funcirclegames.com/modes) - [Music Ball Simulator](https://funcirclegames.com/music-ball-simulator) - [MIDI Ball Simulator](https://funcirclegames.com/midi-ball-simulator) - [How it works](https://funcirclegames.com/how-it-works) - [Pricing and plans](https://funcirclegames.com/plans) - [FAQ](https://funcirclegames.com/faq) - [Blog](https://funcirclegames.com/blog) - [Tutorials](https://funcirclegames.com/tutorials) ## What makes it different - 8 distinct simulation modes — more creative range than tools that only do ball-in-rings - 1,000+ editable physics parameters for exact control over motion and sound - True music/MIDI sync where each bounce triggers the next note in the melody - 4K, 9:16, no-watermark export built for short-form social video
