This game has some similarities with 9 mens morris (and variants). The Red player has 15 red pieces, the Blue player has 15 blue pieces. Players start with their pieces off the board. In Phase 1 the players take turns to place their own counters on the empty corner points of any triangle, square or hexagon. Phase 2 starts when all 30 pieces are on the board. The players continue by sliding pieces along the lines to neighbouring, vacant points.
 
The following rules apply to both phases:

• A piece can only be placed on a corner point, not along on a line.
• Pieces do not jump over each other, nor can two pieces occupy the same point.
• If a piece is blocked in, it can't be moved until a neighbouring point becomes vacant.
• If, by occupying a point, a player takes control of all three points of a triangle, the player can reposition ONE of its opponent's pieces from the point it is on to any other unoccupied point on the board. (NB You can do this in Phase 1, as the pieces are being placed on the board).
• If, by occupying a point, a player takes control of all four points of a square, the player can reposition TWO of its opponent's pieces from the points they are on to any other two unoccupied points on the board.
• If, by occupying a point on a square, a player simultaneously takes control of both a square and a triangle combination (a "house" shape) or two squares, the player can only reposition TWO of its opponent's pieces from the points they are on to any other two unoccupied points on the board.
• The first player to take control all six points of a white hexagon, or a hexagon of their own colour, wins!
• If a player cannot make a legal move, they pass and their opponent continues. (I can't see how you couldn't make a move though).
• Both players have to agree a draw.
• Optional rule that is implemented here: It is not permitted for a player to rebuild a triangle, square or "house" with the same constituent pieces until two turns have passed.
