What is a White Whale?
The White Whale is a floating blimp that produces 2 fuel every 5 minutes, can be speeded up by watching an ad or with 2 Airport cash
Steps to link your account :
1. Register on the trail.gg website (Preferably with same details as your main account such as Email, Username, etc)
2. Login and click on airport city, wait for game to load (NOTE : Do not switch tabs when the game loads, otherwise it will take a very long time to load and may even show error)
3. Once game is loaded, go to your IOS game and copy the GI link code from link progress under settings option. once noting down the code, close the main game app completely (Note : If you don't close the app you wont get the white whale)
4. Go to the Settings option in website game, go to link progress and select the option link progress from other device, enter the code you noted down from main game.
5. Once the code is entered select the server version option when asked which version you want to keep. (Note : this is a very important step, choose carefully as you may loose all your progress if you select the wrong version, also you can see how many coins and airport cash you have but can't see any other stats so choose carefully)
6. A pop up appears saying you receive a white whale as gift, collect it and play game in website for 2 to 3 minutes, then close the game in the website.
7. Open your main game and immediately after the loading screen, app asks which version you want to keep, select the server version again. (Note : this is again a very important step, choose carefully as you may loose the white whale on your IOS and maybe even on website)
8. Search the airport for the white whale and you might find it mostly near airport or airport side expansions, it may even go to the ends so search thoroughly, if you don't find it message here I can try rectifying the issue
That's it, please keep in mind the note points.
