About Tetris
Created in 1984 by Soviet engineer Alexey Pajitnov, Tetris is universally acclaimed as one of the greatest puzzle video games ever conceived. Players manipulate falling geometric shapes called tetrominoes (each consisting of 4 square blocks) onto a 10Ć20 playing field. When an entire horizontal line fills with zero empty gaps, it vanishes and awards points.
Advanced Stacking Strategies
Keep the Well Open
Leave a single vertical open column on either the far left or far right boundary. Save long cyan āIā tetrominoes to trigger lucrative 4-line Tetris clears.
Maintain Flat Terrain
Avoid creating spiky pillars or deep jagged overhangs that block pieces from fitting cleanly into underneath pockets.
Utilize the Hold Box
If an incoming tetromino is awkward for your current board state, press āCā to swap it into the hold chamber for later tactical deployment.
Frequently Asked Questions
What is a "Tetris"?
A "Tetris" occurs when you drop a long straight 4-block piece (the I-tetromino) to clear four full rows simultaneously, which yields the maximum score bonus.
What is the ghost piece?
The faint outline at the bottom of the matrix is the ghost piece projection. It displays exactly where your active tetromino will lock into place if dropped immediately.
How do levels advance?
Every 10 lines cleared elevates your level by 1, steadily accelerating the gravitational drop speed of incoming blocks.
