Klax (video game)

Klax is a puzzle video game released in arcades in 1990 by Atari Games. It was designed by Dave Akers and Mark Stephen Pierce. The object is to catch colored blocks tumbling down a machine and arrange them in colored rows and patterns to make them disappear. "Klax" was originally published as a coin-op follow-up to "Tetris", about which Atari Games were tangled in a legal dispute at the time.
The Atari 2600 port, released in the summer of 1990, was, along with the game "Fatal Run", the last game for the system before the console was discontinued in early 1992.
Gameplay.
"Klax" features a conveyor belt at the top of the screen. It constantly rolls toward the playing area, delivering a steady supply of blocks. The player controls a small device which sits at the interface between the conveyor belt and the playing area, which can be moved left and right to catch the blocks and deposit them either in the playing area (which can hold 25 blocks in a 5X5 arrangement) or push them back up the conveyor belt. The device can hold up to five blocks. An uncaught block is considered a "drop". A flashing block can be used as a wildcard on any colour. In the playing area, blocks can be eliminated by arranging three or more of the same color into a continuous line, known as a "Klax." The line may be horizontal, vertical, or diagonal. A multiple grouping (e.g., one vertical and horizontal) counts as multiple Klaxes, as do Klaxes of four same-colored blocks (two Klaxes) or five same-colored blocks (three Klaxes). Once the goal is reached, bonus points are awarded for remaining blocks on the conveyor belt and device, and empty spaces in the bin (also, on levels where a certain point total is required, points in excess of the required amount are counted both in the scoring and as bonus points).
Klax consists of 100 levels grouped into blocks of five. At the beginning of the game and after each fifth level (levels divisible by five, except for Levels 95 and 100), a player can choose to skip five or ten levels. Skipping levels gives bonus points and a higher drop allowance. The game ends when the player either exhausts their drop allowance, fills up their playing area, or finishes level 100.
Development.
Akers programmed "Klax" in just a few weeks using AmigaBASIC, then ported it line by line to C. In a 1990 interview, he said he wanted to "produce something playable, compact and relatively quick to develop." His influences were both Tetris and tic-tac-toe. He chose the name from the sound tiles make rolling across the screen. Atari Games released "Klax" in February 1990, and soon called it a "major arcade hit". They quickly released several home versions under the Tengen brand. Akers created the Nintendo Entertainment System and Genesis editions himself. Some 16-bit conversions featured improved graphics. "Klax" received the Parents' Choice Foundation's seal of approval in 1990, won Best Mind Game at the 1991 European Computer Leisure Awards, and Dennis Lynch of the "Chicago Tribune" named Klax the Best Cartridge of 1990.
Midway Games gained the rights to "Klax" upon purchasing Atari Games in 1996. The title has been re-released in retro compilations for modern consoles. A 1999 press release called it Midway's "tic-tac tile puzzle game." Mike Mika, who was working on the Game Boy Color version of the game, placed a hidden wedding proposal inside it. It took his then girlfriend three years to uncover the proposal. Mike Mika also placed a hidden Snake-like game as well as a mini-adventure game within the game as easter eggs.
After the arcade version, Klax saw ports to most contemporary home computers and video game systems of the 1990s, including the Atari Lynx, Amstrad GX4000, and even the Atari 2600 as its final official Atari-licensed release exclusively in Europe. "Klax" was the first game with versions for all three of the 1990s' leading consoles: the Nintendo Entertainment System, the Genesis and the TurboGrafx-16. "Klax" was included in "Arcade Party Pak" for the PlayStation. The game was also reissued in "Midway Arcade Treasures", a 2003 compilation for the Nintendo GameCube, PlayStation 2, Xbox and PC. It also appeared in Lego Dimensions. 
Reception.
In Japan, "Game Machine" listed "Klax" on their April 1, 1990 issue as being the seventh most-successful table arcade unit of the year.
On release, "Famicom Tsūshin" awarded the PC Engine version of the game 30 out of 40. The game was ranked the 26th best game of all time by "Amiga Power" in 1991.
Atari Lynx.
In a capsule review of the Lynx version for "STart", Clayton Walnum commented, "Once you start playing "Klax", a maniac with an Uzi won't be able to tear you away. Not only are the graphics clean and vivid, the music is darn near good enough to dance to and the digitized sound effects and speech are astonishing for such a small unit." Julian Rignall reviewed the Atari Lynx version for CVG Magazine in January 1991 quoting "the game is simple, but very, very addictive" giving a rating of 93 out of 100.
