🧱 Tetris: The Standard for Spatial Reasoning

Few software applications have had as profound an impact on human cognition as Tetris. Analyzed in countless psychological studies, this game induces the "Tetris Effect," a state where the brain begins to pattern-match real-world geometry. We present a faithful HTML5 recreation of the classic puzzle, adhering to modern guideline standards for rotation and randomization.

At a technical level, Tetris is a problem of NP-hard packing efficiency played in real-time. The player acts as a sorting algorithm, attempting to optimize the density of blocks (Tetrominoes) within a 10x20 matrix. It is the ultimate test of working memory and processing speed.

📐 Mechanics: The SRS System

This version utilizes the Super Rotation System (SRS), the modern standard for competitive play. Understanding SRS is key to advanced gameplay:

• Wall Kicks: If a piece cannot rotate because it is blocked by a wall, the code checks adjacent coordinates to see if the piece can "kick" into a valid space. This allows for moves that visually appear impossible.
• Bag Randomizer: The game deals pieces in "bags" of 7 unique Tetrominoes. This ensures you never go too long without a specific piece (like the straight "I" piece), reducing RNG (Random Number Generation) frustration.

🧠 Pro Strategies: Beyond Stacking

1. The T-Spin Mechanic

Advanced scoring relies on T-Spins. This involves creating a T-shaped slot and rotating the T-piece into it at the last second. The game engine rewards this with double points compared to a standard line clear, recognizing the mechanical difficulty of the move.

2. Flat Stacking vs. Mound Stacking

Keep your stack flat. A jagged surface creates dependencies—holes that can only be filled by specific pieces. A flat surface maintains option select, allowing almost any incoming piece to be placed efficiently.

🎮 Controls & Interface

Responsive controls are critical. This build minimizes input delay (DAS - Delayed Auto Shift).

• Move: Arrow Keys.
• Rotate: Up Arrow (Clockwise).
• Hard Drop: Spacebar (Instantly locks piece).
• Hold Piece: C or Shift (Swaps current piece for later use).
