Tetrominoes

Because the shapes - technically known as tetrominoes - come in a random order, it is hard to predict the best way to organize them so that they can form neat rows.

Love, Google. - 25 years ago - June 6th, 1984 to be exact - Alexey Pajitnov created a simple puzzle video game where you moved blocks around (called tetrominoes) to create horizontal lines of blocks to eliminate rows and gain points. ❋ Unknown (2009)

The researchers used Monte Carlo computer simulations of a simple lattice model (think of the lattice as a checkerboard), on which are placed "tetrominoes," which are S -, Z -, L -, J -, T -, rod - and square-shaped pieces. ❋ Unknown (2009)

These, along with the game's regular random battles, reward you with differing arrangements of four-hex pieces, a little bit like tetrominoes. ❋ Unknown (2010)

The object of the game is to manipulate these tetrominoes, by moving each one sideways and rotating it by 90 degree units, with the aim of creating a horizontal line of blocks without gaps. ❋ Unknown (2009)

A pseudorandom sequence of tetrominoes - shapes composed of four square blocks each fall down the playing field. ❋ Unknown (2009)

Puzzlers featuring the familiar format of clearing out a wave of blocks, shapes, jewels, tetrominoes, bits and who knows what else have graced every gaming console known to man. ❋ Unknown (2009)

In the game a player rotates and moves different falling tetrominoes, or shapes made up of four adjacent square blocks. ❋ Unknown (2009)

The WiiWare update of the classic puzzling franchise supports the Wii Balance Board - presumably seeing players shift their weight left and right to direct the tetrominoes as they fall. ❋ Unknown (2008)
