Balthazar nodded his head in approval. "Very good, Max! You are indeed clever. Now, open the box and face the next challenge."

At first glance, Level 300 presents an image of deceptive simplicity. The screen shows a serene living room. A cat sleeps on a rug. A grandfather clock ticks in the corner. The instruction reads: “Wake up the cat.” A normal puzzle would offer a bell, a string, or a loud noise. But Brain Test 4 has spent 299 levels teaching the player that the obvious solution is a trap. Clicking the cat does nothing. Dragging the clock’s pendulum yields no sound. Tapping the word “cat” in the instruction—a trick from Level 47—merely highlights the text. The player begins to cycle through the game’s greatest hits: turning the phone upside down, covering the light sensor, even attempting to blow into the microphone. Nothing works.
