### Platforms

Atari/Tengen has published official Klax® brand games for at least the following systems:

Homebrew game publisher Pin Eight plans to introduce an unofficial version for the Game Boy Advance called "Convey" in 2003. Further details are unavailable as of this writing.

I find the NES version to have the best control among all versions I've played. In addition, it's one of the few versions to have real background music during gameplay; the others have only sound effects.

There are actually at least eight colors of tiles, plus a flashing wildcard tile.

### Controls

- Joystick left, right: Move paddle
- Joystick down: Advance tiles faster
- Joystick up: Throw top tile halfway up the conveyor
- A: Drop tile into bin

### Advancing levels

A 3-in-a-row of the specified type counts as one KLAX for advancing to the next level. A 4-in-a-row counts as two, and a 5-in-a-row counts as three. This does not increase in chains. Some levels require the user to survive `n` tiles or to score `n` thousand points.

Making a KLAX stops the conveyor belt for about two seconds. Thus, it is possible to make a vertical 4- or 5-in-a-row. You can make a horizontal or diagonal KLAX chain to a vertical 4-in-a-row, or you can "manual combo" by placing three tiles in one place, then finishing a vertical 4- or 5-in-a-row before the conveyor starts again. (Manual combo works in Klax and in Magical Drop but not in Tetris Attack.)

### Scoring

Most games give 5 points per tile caught. Points are also awarded for KLAXes:

- 3-vertical: 50; 4-vertical: 10,000; 5-vertical: 15,000
- 3-horizontal: 1,000; 4-horizontal: 5,000; 5-horizontal: 10,000
- 3-diagonal: 5,000; 4-diagonal: 10,000; 5-diagonal: 20,000

Making one KLAX and then making another KLAX through chain-reaction or manual combo earns 2x points for the second KLAX, 3x points for the third, 4x points for the fourth, etc. Making two KLAXes at once (such as a horizontal and diagonal) scores 2x; making one KLAX and then two (e.g. a horizontal that chains to two verticals) scores 1x and then 3x. In general: **In each step of a chain, you get the basic number of points for the KLAXes made in that step times the total number of KLAXes made so far in the chain.**

In points waves, any points scored over the requirement count double.

At the end of a level, you get 200 points for every empty space in the bin and 25 points for every tile on your paddle or on the conveyor. There's also a substantial bonus for using the warp at the end of every fifth wave.
