Over at re/code, the artist for Threes! has revealed some design prototypes for the elegant and minimal mobile game. It turns out it wasn’t always so minimal and elegant. The game went through numerous iterations before coming to the simple, clean look we know and play daily. But that doesn’t mean it was any less of a looker. You can track the evolution of its visual design from a set of lurid yet simplistic rectangles, to a rough approximation of tribal folk art, to cards of little monsters with googly eyes, to its final polished and clean look. I’d say it was worth the six-month effort.
