Designed by Jason Franzen and Adrian Johnson ,Â KERNÂ is a game for the type lovers and graphic designers alike. Inspired by the notion of Kerning (aÂ process of adjustingÂ letterÂ spacing in aÂ proportionalfont - wikipedia) KERN brings together the ever so loved Helvetica font in the form of a game of spaces. The task is toÂ precisely place a missing letter into a falling word while avoiding any unnecessary ligatures. The more you play the better you get. So, do you know your Helvetica as well as you think?
