# About Retro Block Puzzle

Retro Block Puzzle is a timeless and addictive puzzle game that challenges your spatial awareness and quick thinking. Based on the classic arcade hit, this version offers a clean, modern aesthetic with smooth, responsive controls. The objective is simple: manipulate falling geometric shapes, known as tetrominoes, to create solid horizontal lines on the grid.

As you clear lines, you earn points and make space for new pieces. The game's pace is steady, requiring you to think ahead and plan your placements carefully. The ultimate goal is to survive as long as possible and rack up the highest score before the blocks stack to the top of the screen. It's a perfect game for a quick break or an extended session of strategic fun.

## How to Play

The goal of the game is to score as many points as possible by clearing horizontal lines of blocks.

-   **Falling Blocks:** Colorful blocks of different shapes will fall from the top of the screen one at a time.
-   **Positioning:** Move the blocks left and right, and rotate them to fit into the gaps in the stack below.
-   **Clearing Lines:** When you completely fill a horizontal line with blocks from edge to edge, that line will disappear.
-   **Scoring:** You score points for every line you clear. Clearing multiple lines at once (a Double, Triple, or a 4-line "Tetris") will earn you significantly more points.
-   **Game Over:** The game ends when the stack of blocks reaches the top of the screen, leaving no room for new pieces to enter.

## Features

-   **Classic Arcade Gameplay:** Experience the timeless and addictive fun of a retro block-stacking puzzle game, right in your browser.
-   **Intuitive Controls:** Features simple keyboard controls for desktop and full touch support (tap-to-rotate, swipe-to-move) for mobile devices.
-   **Responsive Design:** The game's display automatically adapts to fit any screen size perfectly, ensuring a great experience on desktop, tablet, or phone.
-   **High Score Challenge:** With a dynamic scoring system that rewards clearing multiple lines, the game encourages you to aim for massive combo scores.

## Controls

The game offers simple controls for both desktop and mobile players.

**Desktop:**
-   **Left/Right Arrow Keys:** Move the current piece left or right.
-   **Up Arrow Key / X Key:** Rotate the piece 90 degrees clockwise.
-   **Down Arrow Key:** Speed up the piece's descent (soft drop).
-   **Spacebar:** Instantly drop the piece to the bottom (hard drop).

**Mobile:**
-   **Swipe Left/Right:** Move the piece.
-   **Tap the Screen:** Rotate the piece.
-   **Swipe Down:** Instantly drop the piece to the bottom (hard drop).

## Tips & Strategies

-   **Plan Ahead:** Always keep an eye on the stack below. Don't just focus on the current piece; think about how it will affect the placement of future pieces.
-   **Build for a Tetris:** Try to build your stack flat, leaving a single-column gap along one edge. This sets you up to clear four lines at once with a straight "I" piece for a huge score bonus.
-   **Avoid Creating Holes:** Try your best not to leave empty, unfillable gaps in your stack. These can be difficult to clear and will quickly lead to a game over.
