Serpentiles is the name coined by Kurt N. Van Ness for the hexagonal tiles used in various edge-matching puzzle connection abstract strategy games, such as Psyche-Paths, Kaliko, and Tantrix.[1] For each tile, one to three colors are used to draw paths linking the six sides together in various configurations. Each side is connected to another side by a specific path route and color. Gameplay generally proceeds so that players take turns laying down tiles. During each turn, a tile is laid adjacent to existing tiles so that colored paths are contiguous across tile edges.
Serpentiles is also the name of a single-player puzzle connection game developed by Brett J. Gilbert and published by ThinkFun in 2008. The Serpentiles (2008) game includes square (1×1) and rectangular (2×1) tiles and challenge cards which provide a list of tiles that should be arranged to make a contiguous path.
