Here’s a quick tutorial to help you unseal all Blue Doors in Blue Prince and continue your journey more smoothly.

There are Blue Doors in Blue Prince that are sealed from the beginning of the game. Players cannot get access to these doors right away. However, there’s always a way to solve things in a puzzle game. So, if you follow certain steps, you will unseal these Blue Doors in Blue Prince. In this guide, we will try to give you a path to walk on and unlock those doors.
Unsealing Blue Doors in Blue Prince
So far, we have only observed one way of obtaining access to these Blue Doors. If there is no other choice left, you can experiment by swapping a few steps and rearranging their order. But for the most part, try following the sequence of actions given below:
- It all starts with getting the Royal Scepter from a Treasure Trove. When picking the item, make sure that you select the blue color. Once you have it, make sure that you end each day in a blue room to ensure the scepter doesn’t get lost. If it does, simply visit any Treasure Trove and claim it back. Also, make sure to grab some coins; they will come in handy.
- Next, you have to visit the Shrine. If you haven’t already built one, craft it as an outer room. Drop some coins in the bowl in the center and then take them back. This will make you cursed.
- Now, you must visit the Gift Shop. Make sure that you have unlocked Room 46 first because, without it, there will be no Gift Shop. Once you are cursed and have unlocked the Gift Shop, you can buy a new item there called the Cursed Coffers, which will be permanently added to the Shrine.

- Now, revisit the Shrine and open the Cursed Coffers placed at the bottom of the small staircase leading to the shrine statue. The game will warn you but open it anyway and you will obtain the Cursed Effigy.
- The next step requires you to go to Room 46 and grab the Crown of the Blueprints there. Then, make sure to head to the Throne Room and upgrade it to the Throne of the Blue Prince.
- The final step is to simply craft 8 blue rooms in a row to unlock all sealed Blue Doors. This notification will appear on your screen once you have completed all tasks successfully. Try crafting different blue rooms every time.
