This puzzle is my best attempt at imitating AnalyticalNinja for Scojo's weekly prompt, which featured an impersonation challenge. Each setter participating in the challenge created two puzzles: one representing themselves and another impersonating a different setter. Scojo and the chat will solve both puzzles for each setter (the real and the imposter) and try to identify which one is the genuine setter.

Thank you, AnalyticalNinja—it was an absolute pleasure trying to impersonate you!

Rules:

Numbered Rooms: Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.

Arrows: Numbers on arrows sum to the number in the attached circle.

This puzzle is solved in two stages:

Stage 1: Each 3x3 box is solved independently as a 3x3 mean mini. (each box uses exactly three digits from 1-9 without repeating in the rows or columns of that box.) During this stage, numbered rooms clues only see into the first 3x3 box the clue sees.

Stage 2: Delete all digits except for the central cell of each 3x3 box. Then solve the puzzle as a regular 9x9 sudoku using the remaining digits as givens. Numbered rooms clues function as normal in this stage.
