"Kippis" is indeed a good translation for "cheers", being very informal. "Maljanne" translates approximately as "A toast to you [Sir]", the polite form of address being implied by the suffix "nne". One might also say " n malja!", meaning "A toast to !". To say that these forms are never used in Finland is simply incorrect; their place is at a formal dinner party, for example. "Pohjanmaan kautta" might possibly be derived from a historical event: literally translated it means "By way of Ostrobothnia", and Ostrobothnia is precisely the way by which Finnish Jäger troops of the Royal Prussian 27th Jäger Battalion came back from training in Germany, to contribute to the victory of the "whites" in the Finnish Civil War. On the other hand, it might simply be derived from the fact that "Pohja" literally means bottom, therefore "Pohjanmaan kautta" means "bottoms up". Also, while "terveydeksi" does mean "to your health", it is to my knowledge used exclusively when someone sneezes, like gesundheit or bless you. It might, however, appear as part of a more elaborate toast.
Thank you to : Ilkka Poutanen
Kippis. Maljanne
Kippis is the most common way to say cheers but "maljanne" is very rear. It is very polite way to say your toast. That is never used in Finland.
There is also "Hölkyn kölkyn". It doesn't mean anything but it sounds funny. That is used when you want to be funny or if you want to make foreign tourists to laugh.
"Pohjanmaan kautta" means bottoms up. Pohjanmaa is a large area in the north west Finland. "Pohjanmaan kautta" is widely used E.g when you drink vodka.

Vielen danke zu Dr.Wilram Tiemann :

Der Georgier sagt: "vakhtanguri", wir sagen "prost", der Engländer "cheers" und der Däne "ska&ål". Dies ist nicht richtig. Der Georgier sagt zu einer Gruppe vonm Menschen: "Gaumardschoss". Dies bedeutet: "man möge siegen". Zu einer Einzelperson sagt der Georgier: "Gagimardschoss", das soviel wie "du mögest siegen" bedeutet. Also in kartuli ena (=georgischer Sprache) heißt "prost": Gaumardschoss. Michail Saakaschwili oder Aduard Schewardnadse würden nie: "vakhtaanguri" sagen . "vakhtanguri" sagen nur die im Landesteil Gurian lebenden Menschen. Diese haben auch einen eigenen Dialekt. Guria liegt im Südwesten von Georgien. Woher ich das alles weiß? Meinen Freund, ein deutscher Offizier, der mehrere Jahre dort leben mußte, wollte ich mit dem Wort " vakhtanguri" überraschen. Dann wurde ich aufgeklärt. Mit freundlichen Grüßen und "prost" oder besser "ska°l". Ihr Dr.Wilram Tiemann

Most common : Gagimardschoss / Gaumardschoss Only in some parts of Georgien (Vakhtanguri)

German (Germany)

Prost (beer)
Zum Wohl (wine) (to your health)
Hau weg den Scheiss (vulgar)
I would pretty much prefer the first (common) one as the second one is never used at all. You should remove it. 'Gruss Got' is used to welcome a person but not at all in the sense of 'cheers'.

From Stefan Brede
In Germany we have different ways to say "Cheers" or "Slainte", depending on the kind of drink as well as on the occasion. For BEER: "Prost!" (no matter at which occasion). For WINE: "Prost" with friends, "Zum Wohl" in a more formal environment. For COCKTAILS: Here we often use a toast, for example: "Auf uns!" (To us!) or "Auf Dich!" (To you!). For SCHNAPS: Here we often say something like "Und weg!" or "Hau' weg das Zeug!" (Down the hatch!), but "Prost!" is fine as well. For WHISKY: We never say "Prost!" with Whisky. Rather, we use "Cheers!" or a toast, like "Auf Schottland!" (To Scotland!).

Malaysia

In Malaysia the language is "Bahasa Melayu" (meaning "malay language"). As "Basaha Malaysia" it has been brought in line with Indonesian and the two are very similar now.
Experience from the Eastern Malaysia in Sarawak, Borneo where for a toast they would simply say "Minum!". Which means "drink!". Simple but effective.
