About Stack Unblocked

Stack is a minimalist and addictive timing-based game where you drop blocks to build as tall a tower as possible. The challenge lies in precision — misaligned blocks shrink, making the stack harder to continue.

How to Play

Click or tap the screen to release a falling block.
Observe the block above and time your drop so it aligns perfectly with the previous layer.
Each perfect drop keeps the block’s full width; misaligned drops narrow the block and increase difficulty.
Continue stacking until you miss — game ends when block misses or becomes too small.
Try again to beat your previous high score and aim for taller towers.

Game Features

🧱 Simple Mechanics

Tap or click to drop blocks — basic enough for anyone to start playing.

⏱️ Precision & Timing

You must time each drop perfectly to stack blocks without shrinking them.

📈 Endless Progress

See how high you can build — the game continues until you miss a block placement.

🎯 Increased Challenge

As tower height increases, precision demands grow — one mistake can end the run.

🏆 Compete With Friends

High-score chasing and repeat plays make it a fun competitive pastime.

Game Tips & Strategies

Focus on each drop — rushing will cause misalignments and shrink blocks.
Tap when the block’s edges align exactly — even slight misalignment adds difficulty later.
Stay calm — tower height increases stress and makes precision harder.
Practice timing — rhythm helps, tapping in a steady pattern improves accuracy.
Take breaks between runs — fatigue reduces reflex precision and leads to mistakes.
