Tetris – Block Stack Challenge | Classic Falling Blocks Game Online

Tetris – Block Stack Challenge is a modern take on the legendary falling-block puzzle concept. Your objective is to rotate and position descending shapes to form complete horizontal lines. When a line is filled with no gaps, it disappears — giving you more space to survive.

The longer you last, the faster the blocks fall. Precision, quick decision-making, and smart stacking are essential to achieving high scores.

Core Objective

Blocks made of four squares fall from the top of the screen. You must place them strategically to avoid gaps and prevent the stack from reaching the ceiling.

• Rotate pieces to fit tight spaces.
• Create complete horizontal lines.
• Clear multiple lines at once for higher scores.
• Keep your stack flat and controlled.

Understanding the Shapes

The falling shapes are known as tetrominoes, geometric figures made of four connected squares. Mastering how each shape rotates and fits together is the key to advanced play.

Controls

• Move Left / Right: Arrow Keys
• Rotate: Up Arrow
• Soft Drop: Down Arrow
• Hard Drop: Spacebar (if supported)

Quick and confident inputs make a big difference as speed increases.

Stacking Strategy Tips

Keep the surface of your stack as flat as possible to reduce difficult placements.

Leave space for long straight pieces if you want to clear multiple lines at once.

Avoid creating deep vertical gaps — they are difficult to fill later.
