-->-- Title screen for ''Klax''

1989 game built by {{Atari}}. Coloured tiles tumble down from above; you have to catch them on your paddle and drop them into a 5×5 bin. They vanish when you line up three or more of the same colour, a feat referred to as a "Klax". The paddle can hold up to five tiles.

A simple premise: FallingBlocks plus MatchThreeGame. Of such things, life-shattering events are made. Definitely NintendoHard.

The game is 100 levels ("waves") in length, giving the player the opportunity to skip five or 10 of them every five levels, but never allowing you to skip past the 91st stage. So a minimum start-to-finish playthrough is 40 levels long. To pass a level, you have to meet its requirements in order in (almost) each set of five waves: make a number of Klaxes, make a number of ''diagonal'' Klaxes, achieve a certain score, survive a set number of tiles, and make a number of ''horizontal'' Klaxes. You lose if you fail to catch a certain number of tiles (three, four or five, depending on how far you warped at your last chance) during a set of five waves, or if you fill the bin entirely without clearing enough tiles.
!!''Klax'' provides examples of:
* AnnouncerChatter
* CatchPhrase - Many, given by the voice synthesizer.
* CriticalExistenceFailure - All is well until you drop that last tile and then: "Awwwwwww"
* DifficultyByAcceleration - As the stage continues, the pieces become more dense requiring faster reaction time. Sometimes, you also receive that wonderful hint: "This one is fast!"
* FallingBlocks
* HintSystem: A hint is displayed on the objective screen before each wave.
* HoldTheLine - The survival waves, where you must catch a certain number of tiles to win.
* MatchThreeGame
* NoPlotNoProblem
* NothingIsScarier - With regard to the arcade version's complete lack of soundtrack. Some nice, soothing background Muzak would be well placed, but no, all you get is the relentless ''clack, clack, clack''...
* OneWordTitle: Named after the sound of falling tiles.
* PaletteSwap - All the tiles, except in the Game Boy version.
* PathOfMostResistance - While you get a nice bonus, extra leeway on dropping tiles, ''and'' you skip the intervening levels when you warp, you can get a far higher score playing through every single level.
* ScoringPoints
* SoundCodedForYourConvenience - In the arcade version, each colour of tile produced their own unique sound effect as they tumbled.
* SpeedMetal - The NES port's soundtrack by BügSük (Lx Rudis and Dave O'Riva).
* AWinnerIsYou - A little congratulatory sentence [[spoiler: and a bonus 1,000,000 points]].
