Sand Blast Block Puzzle

Key Points

• Objective: Place blocks to create horizontal lines of the same color (left to right) to clear them and earn points.
• Core Mechanic: Players receive 3 differently colored blocks each turn. After placement, blocks transform into sand that flows downward based on gravity, requiring players to predict sand flow to form same-colored lines.
• Game Modes: Includes an endless mode, potentially with high-score or clear-target modes.
• Unique Feature: Sand physics adds strategic depth, as blocks flow as sand after placement, enhancing visual satisfaction.
• Game Over: The game ends when sand stacks to the grid's top, preventing new block placement.

Detailed Game Rules

1. Game Interface

• Played on a rectangular grid, typically 10 columns × 20 rows (dimensions may vary by version).
• Sand accumulates at the grid's bottom, and players place blocks to form same-colored lines.
• Visual effects highlight sand flow and stacking.

2. Block Generation and Placement

• Generation: Each game cycle provides 3 differently colored blocks, potentially with varied shapes (e.g., Tetris-like I, O, T, L, J, S, Z).
• Placement: Players select a block and place it anywhere on the grid. Upon placement, the block transforms into sand, flowing downward to fill gaps based on gravity.
• Sand Physics: The defining feature is the sand flow. Placed blocks disintegrate into sand particles, following simple physics (similar to cellular automata) to fill lower empty spaces. Players must predict the sand’s final position.

3. Line Clearing

• Condition: A horizontal row (from left to right) filled entirely with sand of the same color is cleared.
• Effect: Cleared rows disappear, and sand above falls to fill the gaps.
• Color Requirement: Rows with mixed colors are not cleared; the entire row must be a single color.

4. Scoring System

• Base Score: Clearing a row awards a fixed score (e.g., 1 point per pixel/row).
• Combo Bonuses: Clearing multiple rows at once or consecutively may yield bonus points (e.g., up to 10x multiplier).
• Mechanism: Scores may depend on the number of rows cleared, color, or consecutive clears.

5. Game Over

• The game ends when sand stacks to the grid’s top, preventing new block placement.
• High scores are recorded, encouraging replay to improve.

6. Game Modes

• Classic Endless Mode: Players place blocks and clear lines until the grid fills. Difficulty increases over time (e.g., faster block generation).
• High-Score Mode: Achieve the highest score within a time limit (e.g., 3 minutes).
• Clear-Target Mode: Clear a set number of lines (e.g., 40) without a time limit.
• Battle Mode (Optional): Some versions may include a “battle” element where clearing same-colored lines “damages” a virtual opponent (via a health bar), though this is not core to the game.

7. Difficulty Levels

• Easy: Slower block generation, ample grid space.
• Medium: Increased speed, limited grid space.
• Hard: Faster pace, smaller grid, higher challenge.

8. Controls

• PC/Web Version:
  • Mouse click or Enter: Confirm block placement.
  • P key: Pause game.
  • W/Up arrow: Rotate block (if shapes are supported).
  • A/D or Left/Right arrows: Move block left/right.
  • S/Down arrow: Fast-place block.
• Mobile Version:
  • Tap: Rotate block.
  • Swipe left/right: Move block.
  • Drag down: Fast-place block.

9. Special Mechanics

• Sand Physics: Blocks turn into sand upon placement, flowing downward to fill gaps, requiring strategic placement based on predicted flow.
• Block Attributes: Some versions mention blocks with “unique attributes” (e.g., blocking sand flow or altering direction), though not specified in standard versions.
• Visual Effects: Sand flow and stacking provide satisfying visuals, enhancing the experience.

Game Rules Summary

Objective: The main goal of the game is to place blocks to form horizontal lines of the same color, clearing these lines to earn points.

Grid: The game is played on a 10×20 grid where sand accumulates at the bottom and supports sand flow effects.

Block Generation: Each game cycle provides 3 differently colored blocks per cycle, possibly with varied shapes.

Sand Physics: Blocks turn into sand upon placement, flowing downward to fill gaps, which is the core mechanic of the game.

Line Clearing: When horizontal rows are completely filled with same-colored sand, they are cleared, and sand above falls down to fill the gaps.

Scoring: Fixed points are awarded per cleared row, with combo bonuses for multiple or consecutive clears.

Game Over: The game ends when sand reaches the top of the grid, preventing new block placement.

Game Modes: Includes endless mode, with optional high-score mode (3 minutes) or clear-target mode (clear 40 lines).

Controls: PC uses W key to rotate, A/D keys to move, S key for fast placement; Mobile uses tap to rotate and swipe to move.

Special Mechanics: Sand flow adds strategic depth, and some blocks may have unique attributes (such as blocking sand flow).
