The Dark Dugi variant incorporates the Center Line variant, the Entrapment variant and a modified Blackout variant. The game pieces start using the starting position in the Center Line variant. The basic game is played like regular Dugi with these three variants. The difference being that when a piece is captured either by being sandwiched by two pieces of the same color or by being entrapped…instead of becoming a black out space it becomes a Dark Dugi (which should be a different color then the other pieces, maybe a dark gray). Dark Dugis act like other game pieces: they can move an unlimited number of spaces in any orthogonal direction; can capture other pieces by sandwiching them with two Dark Dugis; can_not land on spaces occupied by other game pieces; can_not move over other game pieces or blackout spaces; can_not move off the board. Unlike other game pieces a Dark Dugi controlled by any player (i.e. on your turn you can move one of your own pieces or a Dark Dugi), also Dark Dugi can_not be captured, but can be entrapped by 4 Blackout spaces on all 4 sides…in which case the Dark Dugi becomes a Black Out space. Dark Dugis create the Blackout spaces…anytime a Dark Dugi moves the space it moved from becomes a Blackout space.
Note: this variant has yet to be play-tested. –Istari–
Quicksand: When a player enters a space, that space gains a token. An empty space with three tokens is blacked out and cannot be re-entered. A piece in a space that has three tokens is safe from the quicksand until vacated. This varient helps with the mobility problem in the endgame, and capture-free moves gain hieghtened significance. A piece that is “trapped” in an area alone, or with a single opposing piece is eliminated.
Clusters movement variant: When two or more pieces are orthogonally adjacent, they may move as a single unit, retaining their oroginal formation, and moving orthogonally as usual so long as the path is not obstructed. Think of it as moving like a Tetris brick. For example, in [http://superdupergames.org/main.html?page=play_dugi&num=2038|Dugi #2038], the piece formation at 13C-13D-12D-11D could move to 14C-14D-13D-12D or 13F-13G-12G-11G or 2C-2D-1D-24D. Of course, clusters can be broken up after being formed; a cluster is still made up of individual pieces, or even other clusters, and those pieces can still be moved as such. Capturing works as usual. - Cerulean, 13 March 2006 (dammit! now I've got the blasted tetris ditty in my head!)
