One Kronos Island puzzle that will doubtless confuse some Sonic Frontiers players is the Tombstone puzzle “A Grave Mystery.” This challenge is located between M-020 and M-023, near the Elder Koco on the northwestern corner of the island. Before starting the puzzle, Sonic will comment that there is a noticeable “pattern on the ground” that reveals how the solution should look. This “pattern” he is referring to is the trails of visible dirt that can be seen in some areas between the tombstones but not others. Accordingly, players can solve the A Grave Mystery puzzle in Sonic Frontiers by aiming the obelisks’ beams of light to match the shape shown by the dirt pattern.
