Zach Gage

New York indie game designer behind SpellTower, Really Bad Chess, Good Sudoku and Puzzmo

About Zach Gage

Zach Gage is an independent game designer based in New York City who makes deep games that are easy to get into, often by taking a classic game and changing only its tools or starting conditions. He is best known for SpellTower, Really Bad Chess (2016), which gives each player a random set of pieces, Sage Solitaire, Good Sudoku, and Knotwords, a clue-less crossword puzzle made with collaborator Jack Schlesinger that later came to Apple Arcade as Knotwords+.

Gage and Schlesinger also co-founded Puzzmo, a daily puzzle site that combines classic crosswords with Gage's own games and new titles, with Schlesinger building many of the puzzle generators. Gage runs a newsletter and Discord for players and shares his design thinking in interviews and AMAs.
