About This Game

Have you ever played Pentomino? You might have without even noticing! Yes, that's true. The well-known tiling puzzle game Tetris has its roots in a lesser-known called Pentominos.

Pentomino is a word derived from two Greek words, "pento" and "domino," meaning a shape that is composed of 5 squares. Developer Alexey Pajitnov once came up with a brilliant idea: "What if Pentominos had dominos consisting of 4 blocks instead of 5?" And thus, the concept of Tetraminos (commercially known as Tetris) came to life.

As of June 6, 2024, Tetris is 40 years old. Needless to say, the game proved itself to be timeless, with millions of users still playing it. OnlineGames.io is celebrating the 40th anniversary of Tetris by offering an HTML5 version.

If you're new to Tetris (or have forgotten about the rules a long time ago), here is the ultimate guide to becoming a Tetris master.

How to Play Tetris?

  • Tetris is a game where you stack colorful blocks in a 20x10 grid.
  • Shapes resembling I, J, L, O, S, T, and Z letters (also known as Tetriminoes) fall slowly from the top of the screen.
  • While the shapes are falling, you can move them to the sides or rotate them to find the ideal angle and location to make the blocks perfectly fit into your grid.
  • When you fill a line completely, all the blocks in that line will disappear.
  • Your main goal is to clear as much as lines as possible before the tetriminoes start falling at a crazy speed.
  • Get the highest score and win this game before all the blocks pile up in a single column.

What is Tetris?

Tetris, a timeless classic, turns 40 in 2024. Rooted in the concept of Pentominos, it was created by Alexey Pajitnov. In this game, colorful Tetriminoes in the shapes of I, J, L, O, S, T, and Z fall from the top of a 20x10 grid. The goal is to stack these blocks to clear lines. OnlineGames.io offers an HTML5 version, which is free, compatible with various devices, and features a neon theme and bonus score mechanism.

How to play Tetris?

Basic Controls

On desktops and laptops, use the A/D or Left/Right Arrow Keys to move the blocks, S or the Down Arrow to drop them, W or the Upper Arrow to rotate, and X to skip a block. On mobile devices, drag the blocks to move and tap on them to rotate. These controls allow players to position the falling Tetriminoes strategically within the grid.

Game Objective

The main objective of Tetris is to clear as many lines as possible before the Tetriminoes pile up and fill the grid. As the game progresses, the Tetriminoes fall faster, increasing the challenge. When a line is completely filled with blocks, it disappears, giving you more space to stack new pieces. The higher the score you achieve, the more successful you are in the game.

Pro Tips

To become a Tetris master, focus on creating long, vertical stacks rather than wide, horizontal ones. This helps in clearing multiple lines at once. Try to keep the well in the center of the grid, which makes it easier to place irregular - shaped Tetriminoes. Also, be strategic with rotations and use them to fit pieces into tight spaces. Don't be afraid to let some pieces stack up if it means setting up a better line - clearing opportunity.
