{{nihongo|'''''Quarth'''''|クォース|Kwōsu}}, known as '''''Block Hole''''' outside Japan, is a hybrid [[Puzzle video game|puzzle]]/[[shoot 'em up]] game developed by [[Konami]] which was released in 1989 as an [[arcade game]]. Besides the arcade version, there were also ports of the game to the [[MSX|MSX2]] (with a built-in SCC chip), [[Nintendo Entertainment System|Famicom]], and [[Game Boy]]—home releases used the ''Quarth'' name worldwide (with the exception of the Game Boy Color release in Europe of ''[[Konami GB Collection]] Vol. 2'', where the game was renamed to the generic title ''Block Game'' for unknown reasons).

''Quarth'' was released on the Konami Net [[i-mode]] service as ''Block Quarth'', with an updated ''Block Quarth DX'' in 2001. It was released without the "DX" suffix in 2005 and was made globally available through Konami Net licensing on many i-mode services offered by mobile operators. In Europe, for example, it was available from [[O2 (UK)|O2 UK]], [[O2 (Ireland)|O2 Ireland]], and [[Telefónica|Telefónica Spain]].

In 2005, [[Konami]] also included the game in the [[Nintendo DS]] title ''[[Ganbare Goemon: Tōkai Dōchū Ōedo Tengu ri Kaeshi no Maki|Ganbare Goemon: Tōkaidōchū Ōedo Tengurikaeshi no Maki]]''. An [[Video game console emulator|emulated version]] of the game was released in 2006 for [[PlayStation 2]] in [[Japan]] as part of the ''[[Oretachi Geasen Zoku Sono]]'' series.
