One of the puzzles that we can find in Sonic Frontiers as part of the mysteries to be solved by the islands, is the one that is related to an ancient door that is locked tight and tight on the fifth and last island of the game, Ouranos Island.

This mystery, which is actually completely optional and has nothing to do with the main story, can be solved to open said door and access an area where portal 4-7 of the island is located. As you may have come this far because you don't know what the final solution to this mystery is, we have prepared this specific entry in our guide in which we show you step by step what you must do to be able to solve the puzzle as easily as possible.

Solution to open the locked door of Ouranos Island

Solution to open the locked door of Ouranos Island

This mystery of the closed door of Ouranos Island is located in the northwestern part of the island and can be solved without any prerequisites, that is, once you reach this last island of the game you can go directly to the location of the mystery to solve it (does not depend on the game's story).

When you reach the place where the mystery icon is marked, you will come across a kind of structure or statue with purple pillars with which you can interact, and behind this, there are three more pillars. When interacting with the central structure, you will hear some musical notes played by a piano.

  • The solution to be able to open the locked door is to replicate the piano melody with the three pillars that are next to the mystery.
  • Each pillar is associated with a fragment of the piano melody.
  • Therefore, you must play them in the correct order so that they complete the entire melody.
  • To make each pillar sound you must encircle by performing a cyber spin.

Luckily, the solution is not too difficult when you already know what you have to do. But if you're still stuck with it, here below is the order in which you need to go around the pillars:

As you can see, first you have to go around the pillar that is in the center; then you must surround the pillar on the left and, finally, finish by surrounding the pillar on the right.

By going around the pillars in this order the piano melody will be replicated perfectly as you could hear when playing the main structure and the gate of the ancestors that was closed will finally open so that you can now access this part of the island.

The most curious of all is that if you previously manage to complete all the challenges on this island, you will be able to teleport to portal 4-7 without having to solve this challenge.
