• Place a digit from 1-9 in each cell such that digits do not repeat in any row, column, or bolded 3x3 box.
• The two shaded boxes are clones, with each digit in the exact same position.
• Maroon lines are entropic lines (E) - any three adjacent digits on a line must contain one of each entropic set: low (1, 2, 3), medium (4, 5, 6), and high (7, 8, 9). Digits on a two cell line must be from different groups.
• Brown lines are modular lines (M) - any three adjacent digits on a line must contain one of each group of residuals modulo 3: one (1, 4, 7), two (2, 5, 8), and zero (3, 6, 9). Digits on a two cell line must be from different groups.
• The grey line is a palindrome (P), reading the same in both directions.
• The brass line is a renban (R), which must form a set of consecutive digits in any order.
• Digits in a cage do not repeat and sum to the number in the top left of the cage.
• The circle contains an odd digit.
