Inspired by A tilt at full rank, I made this puzzle for the occasion of bellal's birthday. 🥳

• Normal sudoku rules apply on the 9x9 grid.
• A tilt at Squishtroquadri:
  • There is a 5x5 tilted grid in the center of the sudoku grid, consisting of the 25 circles.
  • If two circles are on the same diagonal, they must contain different digits.
  • Dashed diagonal lines group the circles in four 9-cell extra regions, and digits do not repeat in these extra regions.
  • Digits on a dashed line belong to multiple extra regions. (For example, r6c4 is in the same extra region as r6c2, but also is in the extra region of r8c4.)
• Skyscraper Arrows: The digit on an arrow indicates the number of circled digits seen in that direction (not including itself), and for that effect circled digits block any lower or equal digit from being seen. (Non-circled digits are ignored)
