Tetra Luciano Rules & Guide

Tetra is the iconic geometric falling-block puzzle game. The objective is to position falling shapes (called tetrominoes or polyominoes) to complete full horizontal rows, clearing them from the matrix and scoring points before the board stacks up to the top.

The 7 Tetrominoes

Each piece is composed of 4 square blocks configured into distinct shapes with standard color coding:

• I (Cyan): The 4-block straight line, the only piece capable of scoring a 4-line TETRA!.
• O (Yellow): The 2x2 square.
• T (Purple): The versatile T-shape used for advanced maneuvers like T-Spins.
• L (Orange) & J (Blue): The two mirror L-shaped hook pieces.
• S (Green) & Z (Red): The two snake / step pieces.

Tips & Strategies

• Keep your stack flat: Avoid building deep wells or spires that make future piece placement difficult.
• Use the Hold queue: If you get a piece that doesn't fit well or you want to save a straight I-bar for a 4-line Tetra, pressing C will save your run.
• Watch the Next preview: Plan ahead by checking the upcoming pieces to build optimal placements in advance.
