"Esiema (from the German: Ameise (read backwards) = \"ant\") was designed in 1989 by Dr. Michael Winkelmann (1945-2015), an Austrian math teacher and game inventor. It was derived from Gulek. The game was published in 1990 by the Vock'sche Werkstatt. It is an unusual two-dimensional sowing game, which can be played by 2 - 6 persons and was derived from Gulek. Its suggested age is 8 and up and a game takes about 20-60 minutes. Esiema is a challenging game also suited for adults as a mindsport. If played with special pieces (cubes, cuboids, triangles, spheres, and so on), it can be played by the blind as well."@en . . "Esiema"@en .
