It’s a classic “15 Puzzle” game. I played such puzzle games before and passed by using intuition and logic. If you have problem with solving such puzzles, google “15 puzzle game solver” there will be some articles/videos or apps that will help you to practice or solve them quicker.
The main problem is solving them QUICK. On the easy difficulty you have 45-90s for making some progress, after it you need to run into office, restore 3 timers from PC and inject game token in Arcades (I recommend collecting 4-7 tokens from: Office (3), Toilets (3), Dinner Hall (1+); and restore all timers before you start solving puzzle).
