# pullapse > Pullapse ("pull" + "collapse") is a free inverse Jenga game that runs in the browser. Tap blocks out of a 2D city of towers and score a point for every block that falls to the street. - Play: https://pullapse.com/ - Price: free, no sign-up, no install - Platforms: any modern browser on phone, tablet or desktop - Contact: support@pullapse.com ## How to play - Tap a block to pull it out. The pulled block itself does not score. - Every block that moves scores 1 point. A block that falls to the street scores 2 points. - A round has 10 pulls. After each pull the city settles (up to 2 seconds) before the next pull. - Drag to scroll the city sideways. - More than 5 points in one pull shows "Nice one!". - There is no fail state. After 10 pulls you see your score and can try a new city. ## Details - Each city is 10 towers of black-and-white blocks, generated from a random seed. The same seed always builds the same city: add `?seed=123` to the URL to replay one. - Color appears only during destruction: every block that moves turns colorful, and particles burst when blocks hit the street. - Built with TypeScript, PixiJS (rendering) and Rapier 2D (deterministic physics).
