Go (game)
Two players, "Black" and "White", take turns placing a "stone" (game piece) of their own color on a vacant "point" (intersection) of the grid on a Go board. Black plays first. If there is a large difference in skill between the players, the weaker player typically uses Black and is allowed to place two or more stones on the board to compensate for the difference (see Go handicaps). The official grid comprises 19×19 lines, though the rules can be applied to any grid size. 13×13 and 9×9 boards are popular choices to teach beginners, or for playing quick games. Once placed, a stone may not be moved to a different point.

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.
