Grave Mystery Puzzle Walkthrough
You must solve this puzzle in Sonic Frontiers as you progress through Kronos Island. The mystery begins as we come close to the tombstones and ends when Sonic has arranged the black tombstones correctly.
If you look closely, you’ll see markings on the ground. These markings are your clue to how you need to align the tombstones. Start with the bottom tombstone. Keep in mind that moving one tombstone will cause the others to rotate. The bottom tombstone should point downwards, just like the markings on the ground. Move the middle-left tombstone so that it points towards the upper-left corner. For the top tombstone, Just let it point downwards. At this stage, if you have aligned the first three tombstones correctly, the fourth one will automatically form this pattern in the image below.
