Destruction with purpose.
Unleash satisfying physical chaos.

Knock Block is an exploration of physical demolition. Clear barriers, track structural loads, and guide Bob and Blinky.

Tactical Physics

Demolition & Vector Mechanics

In our childhood, stacking wooden blocks and knocking them down was our first introduction to physical parameters—mass, force, and gravity. Knock Block translates this tactile pleasure into a digital format. We reject the modern free-to-play model of offering helper items for cash; in Knock Block, success is earned through understanding physics.

You must calculate how mass is distributed across structural elements. A single misplaced impact can collapse a wall prematurely, blocking Bob and Blinky’s path. Find the load-bearing supports and use minimal force to trigger a clean, chain-reaction collapse.

Variables

Gravitational Vector Tuning

Levels feature changing gravity parameters, shifting mass values, and surface friction variables.

Tuning these values shifts how structures slide and collapse, forcing you to constantly adapt your strategy.

Achievements

Global High Scores

Track your level efficiency. Every impact counts against your score. Submit your stats to Game Center to compete for the most efficient demolition runs.

Native Engine & Privacy Integrity

Knock Block is built natively for iOS with a high-performance C-based physics engine, packed into a compact 6.8MB footprint. The game launches instantly, runs with fluid physics rendering, and places no load on your device's cellular data or battery life.

We stand by our minimal data policy. The game does not require an active internet connection to run, collects zero diagnostic analytics, and tracks no identifying user data.

🛡️

Diagnostics Only — Not Linked to You

Knock Block collects zero diagnostic, usage, or performance data. We do not track you, we do not require account registration, and your progress stays 100% on your device.
