Solution to the Canberra level

Mini Metro is a game developed by Dinosaur Polo Club, available on Steam, GOG and iOS store. It was fully released 06 Nov 2015, but was available in early access long before that.

The sigil was added in an update on 13 Feb 2015 (the game was still in Early Access).

Sigil

Sigil appears in the background after going to the credits screen, going back to the main menu and going to the credits screen again.

Clicking the sigil opens the secret map called Canberra.

Sigil appears both in Day Mode and Night Mode, but it's more visible in the Night Mode.

Piece

The player has to solve the Canberra level by recreating the sigil. This is a bit tricky, though, since the solution requires few of the tracks to have T-like connection, which is not possible by the normal rules of the game. This is done by using the "ghost lines" — tracks that have trains still running on them when the track was rerouted.

The piece appears on a popup on screen as soon as the correct arrangement is achieved.

Discovery process notes

The Canberra map was discovered in May 2015 by the community of Mini Metro players.

On 24 Jan 2016, when the GameDetectives were dissecting the game, user /u/nint8835 has modded the game to return true from the function checking if level is solved correctly and got the piece. The legitimate solution was discovered later.

DataMining

The event handler for clicking the sigil in the credits uses the word sigil:

 private void OnSigil(Button button, FTouch touch)
 {
   AudioSystem.Instance.ScheduleEvent(AudioEvent.CreateEvent(AudioSystem.Instance.DspTime, AudioEventType.StartGame, this.Menu.City.City.Clock, 0.5f, 1f, (Line) null));
   this.Menu.StartGame(new Game(GameMode.ZEN, (Scenario) null, new City(CityDatabase.Instance["canberra"], (Randomator) null, 0, false), (Randomator) null, false, (GameRecord) null));
 }

Similarly, the function to check if the solution of the map is achieved is in the getter of IsSigilComplete property. The screen with the piece is GameScreen.Sigil.

The piece is stored in vector data in the PassengerIcon code class. It's defined by 2464 triangles.
