This type is on the upcoming Logic Masters India test, called "Typed Logic," written by some fellow members of Puzzlers' Club. Persistence of Memory is a type I don't have much experience with, but it was fun to write. Unfortunately, the type isn't on puzz.link, so I can only offer an image; still, enjoy! (Ignore the "link" after the puzzle; it won't go anywhere.)
Here are the rules, taken from GMPuzzles: "Draw a snake (a 1-cell wide path) from one dot to the other by moving horizontally or vertically between adjacent squares. The snake cannot touch itself, not even diagonally. All highlighted regions must be visited by the snake, and may be re-entered. If two or more highlighted regions have the same shape and orientation, then how the path passes through those shapes must be identical."
