Tetra Blocks

What Is Tetra Blocks?

Tetra Blocks is a fast-paced falling-block puzzle game inspired by the classic Tetris formula. Players rotate and position four-celled shapes (tetrominoes) as they descend onto a playing field, aiming to form complete horizontal lines that clear from the board. The longer you survive without letting the stack reach the top, the higher your score climbs.

How to Play Tetra Blocks

The objective is simple: arrange the falling pieces to create solid horizontal rows. Each cleared row earns points, and clearing multiple rows at once multiplies your reward significantly.

Basic Controls

• Left/Right Arrows: Move the active piece horizontally.
• Up Arrow or X: Rotate the piece clockwise.
• Z: Rotate counter-clockwise.
• Down Arrow: Soft drop (faster descent).
• Spacebar: Hard drop (instant placement).
• Shift or C: Hold the current piece for later use.

The Seven Tetrominoes

• I-Piece: The straight line, essential for Tetris clears.
• O-Piece: The square block, simple and stable.
• T-Piece: Versatile for T-spins and tight gaps.
• L and J Pieces: Mirror-image hooks for corner placements.
• S and Z Pieces: Zig-zag shapes that demand careful planning.

Scoring System

Points scale with the number of lines cleared in a single drop. A single line nets modest points, while clearing four lines simultaneously (a Tetris) yields the highest base reward. Back-to-back Tetris clears and T-spins trigger bonus multipliers that can dramatically boost your final score.

Strategy Tips for High Scores

Build a Tetris Well

Leave the rightmost column empty and stack pieces nine cells wide across the rest of the board. When the I-piece arrives, drop it vertically into the well to clear four lines at once for maximum points.

Use the Hold Function Wisely

Save your I-piece in the hold slot when building toward a Tetris. This guarantees you have it ready when the well is prepared, rather than gambling on the next-piece queue.

Avoid Creating Holes

Empty cells trapped beneath blocks are nearly impossible to clear without dismantling your stack. Always rotate pieces to fit flush against existing terrain.

Keep the Stack Low

A flat, low stack gives you reaction time and flexibility. When the field gets dangerously tall, prioritize survival clears over chasing combos.
