TETRIS 3D

A Modern 3D Block-Stacking Puzzle Game

3D Fill & Clear is a dynamic 3D puzzle game inspired by classic block-stacking gameplay, redesigned with modern mechanics, immersive visuals, and strategic depth. Players must rotate and position falling 3D block shapes to fill entire floor layers inside a cubic grid. When a layer is completely filled, it clears and awards points.

The challenge increases as the game progresses, introducing faster speeds, special pieces, and strategic decisions.

Core Gameplay

The game takes place inside a three-dimensional grid tower where pieces fall from the top toward the base.

Each piece is made of several blocks forming different shapes. Players must:

• Move pieces across the grid
• Rotate them on multiple axes
• Strategically place them to fill full horizontal layers

When a layer becomes completely filled with blocks, it clears instantly, freeing space and awarding points.

If the stack reaches the top of the grid, the game ends.

Key Features

Fully 3D Puzzle Mechanics

Unlike traditional 2D block games, this game uses a true 3D grid, allowing pieces to occupy space across width, depth, and height.

Players must think spatially to optimize placement and maintain space for future pieces.

Dynamic Camera Rotation

Players can rotate the camera around the grid to view the structure from different angles, making it easier to plan complex placements.

The controls automatically adapt to the camera orientation, keeping movement intuitive.

Multiple Piece Types

The game includes a diverse set of block shapes:

• I piece – long straight shape

• O piece – square block

• T piece – T-shaped structure

• L piece – corner shape

• S piece – zigzag shape

• Dot piece – single block

• Plus piece – complex cross structure

• Bomb piece – special explosive block

Each piece introduces different strategic possibilities.

Special Bomb Blocks

Rare Bomb pieces can appear during gameplay.

When placed, they explode and destroy nearby blocks in a cubic radius, creating space and enabling recovery from difficult situations.

Bombs can also appear automatically when a player reaches a new level.

Progressive Difficulty System

The game becomes more challenging over time:

• Falling speed increases as players clear more layers
• New levels are reached every few cleared layers
• Higher levels introduce faster gameplay

This creates an engaging difficulty curve.

Ghost Piece Preview

A ghost projection shows where the current piece will land if dropped.
This helps players plan accurate placements and perform fast decisions.

Hard Drop & Soft Drop

Players can:

• Soft drop pieces to accelerate descent

• Hard drop pieces instantly to their final position

This adds speed-running and competitive play potential.

Scoring System

Players earn points based on their performance.

Clearing multiple layers at once grants score multipliers:

Layers Cleared	Score Multiplier
1 layer	×1
2 layers	×2
3 layers	×3
4 layers	×4

This encourages advanced strategies and efficient placement.

Two Game Modes

The game currently features two visual environments:

Room Mode

• Classic puzzle environment

• Standard speed progression

Ship Mode

• Faster gameplay

• Brighter visual style

• Increased challenge

Each mode maintains its own high score leaderboard.

Global Leaderboard

Players can compete globally through a high score leaderboard.

The system tracks:

• Player scores

• Game mode used

• Player ranking

Only the best score per player and mode is displayed.

High Score Persistence

The game stores each player’s personal best score for each mode and updates it automatically when a better score is achieved.

Visual Style

The game uses Three.js WebGL rendering to create a sleek, modern visual experience featuring:

• glowing neon blocks

• vibrant color-coded floors

• animated lighting effects

• smooth camera transitions

Each layer of the grid has its own color, helping players visually track height and structure.

Sound & Music

The game features an immersive audio system including:

• background music

• piece rotation sounds

• block landing effects

• layer clearing sounds

• explosion effects

• game-over feedback

The audio engine uses the Web Audio API for smooth playback and looping music.

Controls

Movement

Move pieces across the grid to position them precisely.

Rotation

Rotate pieces around different axes to fit complex spaces.

Drop

Quickly drop pieces to maximize speed and efficiency.

Camera

Rotate the camera to inspect the structure from multiple angles.

Game Objective

Your goal is simple:

Survive as long as possible while clearing layers and maximizing your score.

Efficient placements, quick thinking, and spatial awareness are key to reaching the highest levels.
