Kal-toh was a Vulcan game of intense strategy that could be played solitaire or by multiple individuals. The object of kal-toh, as stated by Tuvok, "Is not about striving for balance but about finding the seeds of order even in the midst of profound chaos." A kal-toh set consisted of a number of playing rods called t'an.
When described by Harry Kim to an amnesic Tuvok, he said "The object of the game is to turn this jumble of rods into a perfect sphere", and that each player took turns to position pieces, the one managing to form the final intended shape winning. (VOY: "Riddles")
When Kim referred to kal-toh as "Vulcan chess", Tuvok commented that, "Kal-toh is to chess as chess is to tic-tac-toe." (VOY: "Alter Ego") Kim played several games with Tuvok, noting that it was surprisingly addictive for a game of pure logic, although he never managed to defeat Tuvok before Voyager returned to the Alpha Quadrant. (VOY: "Alter Ego", "The Omega Directive", "Riddles", "Endgame")
Tuvok, Icheb, and Harry Kim often played a match of kal-toh together. Icheb was quite talented with the game, although Tuvok blamed Icheb's first victory over him on an early manifestation of his degenerative neurological condition. (VOY: "Endgame")
