Corda

Corda is a tricky puzzle for one or more players using rhombs. The rhombs show vines. As a solo puzzle, the player tries to connect the 48 rhombs, which have thick branches or thin vines on their edges, into one continuous picture. As a competitive game, 35 or 36 tiles (depending on the number of players) are dealt out among the players. The remaining tiles are placed openly on the table. Each player now tries to connect his/her tiles into one picture. Players can take turns taking tiles from the table. A player who took a tile is allowed to put one back there as well, but that is not mandatory, so players can opt to increase the number of their tiles.
When no one can place any more tiles, the scoring starts. All tiles a player couldn't use counts 2 negative points. Each placed tile counts two points; this is doubled if the tiles form a closed ring. Points can also be scored by connecting the thin vines. The player with most points is the winner.

The 1986 edition is part of the Franckh-Kosmos/ 'Edition Perlhuhn' series.
