TriGlyphen Good mental workout - finding the patterns is not always obvious. Making a run of patterns is a challenge :) Good thing for wildcards! My new favorite. UPDATE: Playing with the new difficulty settings they just added. As if this game wasn't challenging enough, "master" level is very hard.
