Go (game)
The playing pieces are called "stones". One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections ("points") of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if "captured". Capture happens when a stone or group of stones is surrounded by opposing stones on all orthogonally-adjacent points. The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second). Games may also be terminated by resignation. A teacher might simplify the explanation by saying to a student "you may place your stone on any point on the board, but if I surround that stone, I will remove it."

The puzzles grow in complexity by adding complications to several simple mechanics. Mechanical enemies and obstacles, such as gun turrets and raisable platforms, are hackable via computer terminals on nearby nodes. The player drags their finger on the touchscreen to connect the terminal's node and the hackable device. The character can store an invisibility power-up to move without detection while in an enemy's line of sight. When activated, it lasts two turns. The main game runs about three hours in length, and the player can purchase puzzle solutions through microtransactions. An additional puzzle design node—also new to the "Go" series—lets players make single-screen puzzles to share with others. Square Enix highlights five new puzzles in a weekly rotation. As part of a tie-in with "Deus Ex: Mankind Divided", players complete the main story and weekly puzzles in the mobile game to unlock perks in the console title.
