TwixT

CONNECTION BOARD GAME invented 1962 by ALEX RANDOLPH. Two players (Red/Black) alternate placing pegs on a 24×24 grid trying to connect their two opposite sides with a chain of KNIGHT-JUMP LINKS. Each peg becomes a potential link node; linked pegs form a fence. Signature: LINKS CANNOT CROSS opposing player's links. NO DRAWS in pure form (like Hex). Published by 3M Bookshelf Games; won SPIEL DES JAHRES nomination. Widely considered ONE OF THE FINEST CONNECTION GAMES ever designed alongside HEX + GO.

Frequently asked

TwixT vs Hex — differences?+

Both are CONNECTION GAMES with NO DRAWS. HEX (Piet Hein / John Nash 1942): stones on HEX GRID, adjacent connections. TwixT (Alex Randolph 1962): pegs on SQUARE GRID with KNIGHT-JUMP links; links CAN BE BLOCKED by crossing. Hex has simpler rules but deeper mathematical analysis. TwixT has richer tactics due to the crossing rule + longer link distance. Both are considered CLASSICS of pure abstract strategy.
