Gage specializes in taking well-worn casual game mainstays (word puzzles, chess, solitaire) and twisting them in small, clever ways. Often these are simple mechanical tweaks; Really Bad Chess gives players one king and 15 other random pieces to duke it out with, while Sage Solitaire elegantly splits the difference between classic Klondike and poker. His latest game Pocket-Run Pool is his version of an arcade-style billiards game, with rotating pocket multipliers and three lives (i.e. scratches) to clear the table.
A Zach Gage remix is the best kind of remix. Pocket-Run Pool is certainly enjoyable, but Really Bad Chess remains one of my favorite games on iOS.
