Tetris+

Game Overview

Tetris+ is a modernized, arcade-cyberpunk inspired take on the classic arcade puzzle game. Built using modern web tech (HTML5 Canvas and JavaScript), it updates the standard 10x20 Tetris gameplay loop by adding an expansive pool of exotic new piece shapes, advanced scoring mechanics, and fluid multi-platform layout optimization.

Visually, the game utilizes a dark, neon-accented aesthetic complete with a shifting radial background ambient glow, clean border highlights, and vibrant piece designs.

Core Features & Mechanics

1. Massive 18-Piece Roster

Unlike standard Tetris which only features the 7 classic tetrominoes, this edition expands the gameplay pool to 18 unique pieces, including complex pentominoes and modular custom shapes:

• The Classics (7): I, O, T, S, Z, J, and L blocks.
• The Exotics (11): * U (Cup block)
  • P (Plus/Cross block)
  • X (Mini L-Corner)
  • I3 (Short 3-block flat line)
  • Dot (Single-block sniper)
  • W (Stair-step block)
  • F (Branch block)
  • V (Giant Corner V)
  • LongI (5-block Mega Line)
  • Zilla (Extended double-step Z)
  • BigO (Hollow 3x3 box)

2. Modern Handling Engine

• DAS & ARR System: Features Delayed Auto-Shift (170ms) and Auto-Repeat Rate (30ms) mechanics for highly responsive, top-tier competitive piece-shifting behavior.
• Rotation & Kicks: Implements a custom wall-kick engine configuration featuring specific spatial offsets for standard blocks and elongated straight pieces (I and LongI), allowing players to spin pieces out of tight corners.
• Infinite Lock Delay Resets: Provides a 500ms safety buffer when a piece touches a surface. Players can manipulate the piece up to 15 times before it firmly locks, preventing premature placement mistakes.

3. Advanced Scoring & UI

• Dynamic Combo Engine: Tracks consecutive line clears, scaling bonus points heavily the longer a combo streak is sustained.
• Back-to-Back (B2B) Multipliers: Rewards players who clear 4 or more lines simultaneously in succession with a massive 1.5x score modifier.
• Burst Pop Up Typography: Slings visual text notifications directly onto the matrix field (e.g., "B2B MEGA CLEAR!", "COMBO x3") when pulling off difficult moves.
• Complete Analytics Panels: Monitors Hold Piece tracking, a 3-step Next Queue preview, Level Scaling, Combo Meter, Total Line counts, and Live Scores.

Control Layout Configuration

The game features a context-aware system that checks the hardware layer of the user's device and updates both the UI and the operational mapping dynamically.

Desktop / PC (Keyboard)

• A / D — Shift Left / Right
• W — Rotate Clockwise
• S — Soft Drop (Accelerated gravity)
• J / Z — Rotate Counter-Clockwise
• K / C — Swap Hold Piece
• Spacebar — Hard Drop (Instant floor lock)

Mobile / Tablet (On-Screen Touch Pads)

When loaded on a touch-capable device, the layout rescales the canvas safely and renders two ergonomic touch nodes below the active game matrix:

• Left D-Pad Cluster: * ◀ / ▶ buttons for movement.
  • ▼ for manual soft drops.
  • ▲ for quick clockwise rotations.
• Right Action Cluster: * Dedicated ↺ (Counter-Clockwise) and ↻ (Clockwise) rotation keys.
  • A massive HOLD toggle switch.
  • A full-width HARD DROP bumper baseline button for high-speed play.
