Brain Out Level 132

Overview

Three bulbs sit above three red switches, and the prompt asks to light up every bulb. The wiring behind the switches does not connect to all three bulbs, so one bulb cannot be lit through the normal circuit. The solution removes that unreachable bulb from the screen before operating the working switch.
Three bulbs and three switches look evenly matched at first, but the wiring behind them does not give every bulb a live path to the controls.

• Difficulty: Regular
• Estimated moves: 3

Step-by-Step Solution

1. Count the three bulbs and the three switches. Notice that one bulb has no live path through the switches, so flipping the red controls will never reach it.
2. Drag the third bulb off the edge of the screen to remove it from the puzzle. This takes the unconnectable bulb out of the required set.
3. Press the working red switch to turn on the bulbs that are still connected in the circuit.
4. Check that every bulb remaining on screen is lit. The level completes once the surviving bulbs are glowing and the unusable one has been moved away.
5. If a bulb stays dark after the switch, confirm it is the one you removed; do not keep pressing switches that lead nowhere.

Identify which bulb has no reachable connection through the switches, then drag that bulb off the screen so it is removed from the required set. After it is gone, press the working switch and watch the remaining bulbs light; leave the other switches alone to avoid opening dead branches. The level completes once every bulb still visible on screen is lit and the unconnectable one has been moved away. If a bulb stays dark, confirm it is the one you removed rather than another connected bulb.

After the dead bulb is removed, resist the urge to press every remaining switch just to be thorough; only the connected switch matters, and extra taps on dead controls do not light anything. The finished board shows the surviving bulbs glowing together, which confirms the reduced set has been satisfied rather than the original three.

Strategy & Reasoning

The prompt says all bulbs, but the hidden reality is that the circuit only serves some of them. Brain Out allows you to remove an unsolvable object from the board rather than force an impossible electrical path. Removing the dead bulb reframes the requirement: light every bulb that can actually be lit, and the working switch then satisfies the reduced set. The hidden reality is that not every prop can be wired up, so Brain Out lets you remove an unsolvable object from the board instead of forcing an impossible circuit. Reframing the goal around the bulbs that can be lit, after the dead one is gone, makes the remaining switch operation satisfy the level.

Tips & Common Mistakes

• One bulb cannot be wired up, so move it off-screen instead of hunting for another switch.
• Operate only the switch that connects to the remaining bulbs; extra taps do not help the dead one.
• Judge the goal by the bulbs still visible after the removal, not by the original three.
