Gigachess is a puzzle board hero defense. With your custom party of Knights, Rooks and Bishops, defend against the relentless waves of enemy Pawns running a blitz for the board's bottom. The seemingly unbreakable formations and constant downward march of your foe transform chess from slow burn to tactical rush in this deeply addictive single-player remix of turn-based strategy's ultimate grandmaster.

How long can you survive the pawn onslaught?

  • Endless mode with randomly-generated waves and a choice of 4 difficulty levels for a perpetual Pawn menace (now with Autosaves, Hyper states & Mutators!)
  • Puzzle Attack mode offering 40+ high-stakes, logic-testing stages to clear (now with Easy Mode!)
  • Knight's Dungeon mode providing a 40-stage set of knight's tour-inspired puzzles to maze through (now with a Level Editor!)
  • Playable Tutorials & Tooltips for a crash course in the mechanical intricacies and insight on demand
  • Strategic Power-ups that block advancing Pawns, plant explosive traps & more!
"Gigachess is one heck of a tactics game."
