Accounting Circles Tessellation

(Published on 20. October 2025, 16:03 by ChinStrap)

A constraint I made up that doesn't make sense in normal sudoku contexts but does in Tessellation puzzles. Thanks to all the testers!

Rules:

TESSELLATION:

  • Fill each cell with a digit from 1-9.
  • Cells sharing an edge can't have the same digit.
  • Each horizontal row and vertical column contains a non-repeating consecutive set of digits (like 23456) in any order.
ACCOUNTING CIRCLES/SQUARES:
  • The blue circles and red squares combined form a complete set of digits 1-9.
  • A digit in a blue circle indicates how many of that digit appear in the entire puzzle.
  • A digit in a red square indicates that digit does NOT appear exactly that many times in the puzzle.
  • For example, if there were four 4s and six 5s in the grid, 4 would go into a circle and 5 into a square.

All feedback (positive or critical) appreciated!

Solution code: Row 5, left to right (9 digits)
