Players must visit the Rusty Lake Blog to be informed of a "new drink", a Gin Tonic. If this drink is made in Cube Escape: Theatre, it will indeed make you a gin tonic. This cocktail may be given to Bob, but there will be no effects until he leaves to go into the bathroom. Afterwards, there will be two extra notes on the pilsener coasters, but only one coaster will be of any use. It'll tell the player: "Play BADEGG on the piano". If B-A-D-E-G-G is played on the theatre's piano, Harvey will jump out of the hole where the Hand should be, and begin singing to the Woman's favorite song. Afterwards, a letter will be given to the player by the Hand. When the letter is clicked on, the player is re-directed to a page which enrolls them in the contest.
If the gin tonic was made before the contest was officially announced, the link would instead lead to a separate webpage congratulating the player on finding the secret themselves.
To celebrate the success of Rusty Lake: Roots, Rusty Lake decided to do a giveaway. To participate, a person needed to comment on a post announcing the contest, and subscribe to Rusty Lake's mailing list.
Players needed to find the coordinations to different locations on the map in the Submarine. After a bit of given coordinates, a folder could be found allowing the player to enter the contest. On April 14, 2017, the developers released a clue on social media, pointing to thethreelocations the player needed to visit to eventually find the location of the hidden box containing the folder.
The winners were contacted on May 10, 2017.
