Standard 9x9 sudoku rules apply.

Non-consecutive Portal Loop: Draw a non-intersecting loop through the centers of all unshaded cells. When the loop enters a portal (circled cell) with a number, it must teleport to another portal with the same number and continue in the same direction. Each portal can only be used once. Adjacent digits along the loop cannot be consecutive.

Killer Cages: Digits in a killer cage must sum to the number in the top left corner of the cage. Digits cannot repeat in a cage.

Renban Regions: Orthogonally connected shaded cells make up a renban region. Digits in a renban region must form a consecutive set of digits in any order, without repeats.
