But now two decades later is a colour matching puzzle game worth your attention?
The game actually consists of one hundred levels and your goal is to progress through them. If you set three blocks in a line you have created a "Klax" and initially all you have to do is get a certain number of "Klaxes" to progress to the next level. As the game progresses you'll also have to meet other specific challenges, getting diagonal Klaxes for example of favouring one colour over another. Obviously while striving for this goal you have to always be aware of the blocks on the conveyor belt, as failing to catch one with your controllable paddle counts as "a drop". You have a limited number of ‘drops’ and should you go over this limit, its game over - even if there is still space for blocks on your grid.
The backgrounds are a rather eclectic mix of jungles, space, giant hands and even, oddly, car parks at night. They're thankfully subtle; there if you care to look but so innocuous that I can imagine many players don't even notice.
