Rules: Normal Sudoku rules apply, i.e., place the numbers 1-9 once each into each row, column, and 3×3 box.

Guide a robot from the circled to the caged cell. The robot takes one step at a time to an orthogonally or diagonally adjacent cell. Tell the robot in which direction to move at each step by entering a digit at its current position with your remote control on which the numbers 1-9 are arranged in a 3x3 square with "123" in the top row, "456" in the middle row, and "789" in the bottom row, all written from left to right, like in most online Sudoku-solving tools. The direction in which the numbers are arranged with respect to the middle 5 correspond to the direction in which the robot will move, i.e., 1 = up left, 2 = up, 3 = up right, 4 = left, 6 = right, 7 = down left, 8 = down, 9 = down right. With 5, the robot continues in the same direction as in its previous step.

Shaded cells are obstacles through which the robot cannot pass.

The caged and circled digits are in a ratio of 1:2, in any order.

Example: In the following grid fragment, the robot first moves right (6), then continues its movement along the same direction (5), then moves up right (3), then down (8) to get from the circle to the cage.
