Brain Blow Level 73

Overview

Two stacked control panels face you on a plain white screen. The upper panel has a dark display showing a face silhouette and four small indicator lamps along its top; the lower panel has five indicator lamps above a three-by-three grid of square buttons. The prompt asks you to repeat the sequence. This is a memory-repetition puzzle: the upper machine demonstrates a short pattern of pad positions, and you must enter that same pattern on the lower keypad in the same order. The green lamps on each panel fill in as the sequence progresses, showing how many entries have been accepted.

• Difficulty: Regular
• Estimated moves: 3

Step-by-Step Solution

1. Read the prompt asking you to repeat the sequence, and look at the two panels. Notice the four lamps above the upper display and the five lamps above the lower grid; these lamps track progress rather than acting as buttons themselves.

1. Watch the upper machine run through its demonstration. As it plays, pay attention to which positions on the pad are highlighted in order, and follow the order in which the upper lamps light up one after another.

1. Remember the demonstrated sequence before touching the lower grid. The pattern is short, so keep the first position in mind, then the second, then the third, rather than trying to guess as you go.

1. On the lower three-by-three keypad, tap the squares in the exact same order the upper machine showed. Each correct tap lights one of the lower panel's green lamps, confirming that the entry was accepted before you continue to the next one.

1. After the last square of the sequence is entered correctly, the upper lamps complete their row and the level shows the green checkmark with the completion screen, confirming the sequence has been repeated.

Strategy & Reasoning

The level works like a classic memory game: one device plays a pattern, and the player copies it back. The challenge is remembering both the positions and their order, because tapping the right square in the wrong place in the sequence does not count. The indicator lamps are the feedback channel: a lamp fills only after the corresponding entry matches, so you can tell whether you are on track instead of waiting until the end to find out.

The upper display's silhouette and the plain square buttons are deliberately understated, with no colors or labels to mark the positions, so the only reliable cue is the order the demonstration highlights them. Watching the full demonstration once to fix the rhythm and positions, then repeating from memory, works better than tapping along during the playback. If a lamp does not fill after a tap, the order has slipped; restart the demonstration and watch the sequence again before entering it a second time.

Tips & Common Mistakes

• Memorize the demonstrated order before tapping the lower grid; do not press squares while the upper machine is still playing.
• Match both the position and the order: a correct square entered at the wrong step in the sequence will not light the next lamp.
• Use the green lamps as your check: each accepted entry fills one lamp, so a missing lamp means you should restart and rewatch the pattern.
