Sonic Frontiers players will find all sorts of challenges and puzzles while running around at the speed of sound across the various zones. Players can complete the puzzles littered about the world to reveal new sections of the map and unlock special items. The special items earned are Red Seeds of Power and Blue Seeds of Defense. When taken to the correct person, Sonic Frontiers players can increase their power and defense level.

This guide will help players solve one of the puzzles they might come across in the first area, Kronos Island. The challenge is titled 'M-015', and players might notice that there's a moon icon on the sign. If players come to this challenge during the daytime, nothing will happen; however, if players drop by the challenge area during the night, the puzzle can be started and completed to earn a Red Seed.

How to Change the Time of Day in Sonic Frontiers

To start the M-15 puzzle, players will need to make sure it's night outside. As far as we know, based on our early hours of Sonic Frontiers, there's no way to manually make the time of day pass. In order to make it nighttime, players will just need to wait until the sun goes down. Try and complete other challenges or explore the area and then return to the puzzle once the time passes.

Puzzle M-15 Walkthrough

  • Once it's dark, players will find a glowing strip of light next to the puzzle's sign. To destroy it, use the Cyloop ability by holding the X button (Nintendo Switch), making a circle around it, and closing the loop. For other platforms, the button for using Cyloop is Triangle (PS) and Y (Xbox).

  • Another light strip will pop up to the left of the sign --destroy it for the third one to appear.
  • The third light will appear on the platform northeast of the puzzle's sign.

  • Once the last strip of light is destroyed, players will earn themselves a Red Seed of Power.
