The game was invented by Marino Carpignano in 2016. An 8x8 unchequered game board is used with a certain number of bi-colour counters, white on one side and black on the other, like in Othello. At the beginning, the board is empty. Black moves first. The Black player's first move is obligatorily on one of the 8 squares along the North side of the board. After that, each player will choose an entry square for their counter, placed along one of the two next side rows (clockwise) with reference to the last piece played. A counter slides (also jumping over any other counters already present on the game board) along the line perpendicular to the selected side, and stopping on the first empty square encountered. Ambiguous moves are forbidden: that means you are not allowed to place your counter on a square that may be reached from both sides where you can play in your turn. In this game the counters are captured by flanking them; the result of a capture is instead the same as in Othello. The aim of the game is to be the first to complete an orthogonal or diagonal line of at least four counters of the player’s colour, avoiding a simultaneous alignment of four or more of the opponent’s counters.
