  • Alta uses the official 61-square board from the original W. D. Troyka package.
  • On each turn, place a new diagonal switch of your color or toggle one of your own switches to the opposite diagonal.
  • Blue connects top to bottom; Red connects left to right.
  • Winning connections may use switches of either color, not only your own.
  • You may not place a switch in the three spaces next to each enemy goal node.
  • If one move creates both winning connections, the moving player wins immediately.
