Stacktris

Stacktris is an engaging and addictive puzzle game that combines the classic elements of Tetris with a unique stacking mechanic. With its simple rules, intuitive gameplay, and increasing difficulty levels, Stacktris appeals to players of all ages and skill levels.

How to Play Stacktris:

1. Objective: The main goal of Stacktris is to manipulate falling blocks, known as tetrominoes, to create complete horizontal lines without any gaps. When a line is completed, it clears from the play area.

2. Controls:

   • Left/Right Movement: Use the left and right arrow keys or touchscreen controls to move the falling tetromino left or right.
   • Rotation: Rotate the tetromino by pressing the up arrow key or using a rotation button on the screen.
   • Soft Drop: Increase the speed of the tetromino's descent by pressing the down arrow key.
   • Hard Drop: Instantly drop the tetromino to the bottom by pressing a specific key (e.g., the spacebar).

3. Tetrominoes: Different tetromino shapes consisting of four blocks each will fall from the top of the screen. Tetromino shapes include I, J, L, O, S, T, and Z.

4. Clearing Lines: When you complete a horizontal line without any gaps, it disappears, and you earn points. The goal is to clear as many lines as possible.

5. Speed Increase: As you progress through the game, the speed at which tetrominoes fall may increase, making the game more challenging.

6. Game Over: If the stack of tetrominoes reaches the top of the play area, the game ends. The player's score is based on the number of lines cleared.

Tips:

1. Plan Ahead: Anticipate the best placement for each tetromino to create complete lines.
2. Use Rotation Strategically: Experiment with rotating tetrominoes to fit them into tight spaces.
3. Clearing Multiple Lines: Clearing two or more lines simultaneously (called a "Tetris") scores more points.
4. Maintain an Even Stack: Try to keep the stack of tetrominoes relatively even to prevent uneven gaps.

Controls Guide:

1. Keyboard Controls: Use arrow keys for left, right, and down movement, and the up arrow for rotation. The spacebar is often used for hard drop.
2. Touchscreen Controls: On mobile devices, swipe left or right for movement, swipe down for a soft drop, and use on-screen buttons for rotation and hard drop.
