Final Round in Boku

About Culls, from BoardGameGeek:

To win The Game of CULLS - which has also appeared in print as Bollox, Bolix, and Bōku - you need to get five of your pieces in a row. To set up, one player places two chips lobster-side down on empty spaces on the game board, then the other player does the same, after which players take turns placing one chip lobster-side down. If by placing a chip, you sandwich exactly two of the opponent's chips, turn one of those chips lobster-side up. On that player's turn, they must cull their lobster, picking up the piece and placing it elsewhere lobster-side down as their entire turn. Continue until someone wins.
