Xalk is a match 3type game written by Anthony HENRIQUES in 1991 and published in the issue 33 of the Amstrad 100% newspaper in January 1991, following the release of the game Klax.
In 2017 Anthony HENRIQUES rewrote parts of the game : diagonal matches and combos, bug crushing. The speed at the start of the game is more or less random and the game can be paused with the Space key.
In 2019 Tom et Jerry, Kukulcan for the programmation and Ixien for the music also did enhance the game once more.
