An indie remake was made in 2009 for iPhone, called Gem Panic, and a range of Puzznic clones called 'Puzzle Magic' have appeared on mobiles. Many games share the same basic gameplay of Puzznic but have added extra features over the years:- Puzztrix on the web and on PC, Addled and Germinal on the iPhone, Puzzled on mobile phones.

The game was ranked the 34th best game of all time by Amiga Power.
