Stored Games.  GoRilla uses the SGF gaming format to store games. SGF collections are supported, enabling many games to be held in a game file. Games may be a mixture of the supported ones. Many lines of play can be stored in a game. Information about SGF and the SGF extensions that GoRilla uses can be viewed at [ SGF Extensions ].

Hex,  Havannah,  Unlur,  Kropki,  Onyx,  Y

Hex.  Hex is gaining in popularity on online game sites. For a good introduction visit [ www.hexwiki.org ].

Havannah, Unlur.  [ unlur.html ], [ havannah.html ]. Unlur was invented by Jorge Gómez Arrausi and won the 2002 Unequal Forces Game Design Competition organised by the Abstract Games magazine. Havannah was invented by Christian Freeling. Both games can be played at my online game site, Gorrion.

Kropki.  Kropki [ kropki.html ] is played by two people on a sheet of squared paper. Kropki supports any size up to 45 x 45. Each player takes turn to colour a node of the grid and aims to create regions of territory that surround the opponent's points.

Onyx, Y.  Onyx [ onyx.html ] and Y [ y.html ] are not supported by GoRilla, but can be played at my online game site, Gorrion.
