Turnier, Castille, Claim
Turnier is a 1976 game by Alex Randolph, published at Parker Brothers.
The game consists of eight board sections, each with 12 positions, some rectangular, some L-shaped.

the setup is randomized, so that new matches
always have something unique;
for two players five boards are used
Each player has 18 pieces (towers) and three flag pieces that can be attached.

the shading refers to the four-player version,
with two teams of two players fighting each other
(so the game comes with 72 pieces and 12 flags)
Rules
- In the setup, players alternatively drop towers on empty positions. Then, players remove four enemy towers (also in alternate turns).
- On their turn, a player may move one of their pieces one space orthogonally to an adjacent empty position.
- A piece may jump over an adjacent piece in a straight line if the space beyond is free.
- Multiple jumps are allowed, and after each jump, the direction may change.
- There are several ways to capture an opponent’s piece:
- If, by moving one’s own piece, an opponent’s piece becomes trapped between two pieces of one or two players, it is removed.
- A piece is also removed if it stands at the edge of the board and an opposing piece moves onto the adjacent space directly across from it on the opposite edge.
- After a capture, the player immediately takes another turn if the same piece can make another capture. If a move allows multiple captures, all those pieces are removed.
- When only pieces of one color remain on a game section, the owner receives a flag, which is placed on any one of their pieces in that area. This board is now conquered, even if later enemy pieces can enter it.
- The conquest can only be undone by capturing the flagged piece.
- When it’s their turn, a player may transfer their flag to another piece of the same color within that section.
- If a flagged piece leaves the area, the flag is immediately removed.
- Removed flags cannot be reused later.
- The game ends when one player has three flags on board.
The game has one big problem -- probably what was called a 'fatal flaw' by the author --, after one flag is captured, that player cannot win the game. If the other player also has a captured flag, the game is automatically a draw, since it becomes unwinnable.
A variant was proposed where flags are not used, and one player scores each conquest immediately. This modification does not suffer the same problem.
In 1983, the author made a new iteration of this idea: Claim (later called Die Wikinger Kommen).
It seems that in these new versions, there are slightly different rulings regarding reclaiming board sections:
- in 1983: the enemy flag is removed and replaced with one of yours on any vacant dot of that section; the flag is returned to its owner
- in 1994: the conquered flag is given back to the owner and replaced on the same position with an own one
- in 1996 a Ko rule was added: a player is not allowed to do the same move within three turns without either trespassing a territory or threatening an opponents piece
§
Turnier and Claim were preceded by 1970's Castille, also from Randolph,
where the board sections are fixed:
In this ruleset the flags can be captured but are given back to the player and become available again for future deployment. So, the mentioned design error apparently appeared between this first version and Turnier.
