Rules:

Normal sudoku rules apply.

Escape from the diamond vault by finding a path from the ventilation shaft (r9c9) to the door (r2c1). Your path may only move orthogonally, and may not visit any cell more than once. You may not pass through any coloured display plinths. Also, stepping on any floor tiles with an even digit will trigger the alarms, so don't do that.

The digit on a diamond equals the sum of the digits on all the keys that match its plinth colour (and letter). No two diamonds have the same digit.

Discover these diamond digits to steal them, and find the path to escape the room. You have 45 minutes!
