Brain Blow Level 78

Overview

Grandma stands at a zebra crossing holding her cane, while two red cars are stopped on the crossing and the traffic light beside her shows red. Above the light hangs a circular color wheel split into several colored segments, including a green section. The prompt says she needs to cross the road again. The cars will not yield while the light stays red, so the task is to repaint the traffic light green using the colors on the wheel, after which the traffic clears and grandma walks across.

• Difficulty: Easy
• Estimated moves: 2

Step-by-Step Solution

1. Read the prompt saying grandma needs to cross the road again, and look at the scene: the traffic light beside her is red, cars are occupying the crossing, and a multi-color wheel sits above the light.

1. Tap the red traffic light next to grandma to select it. This is the lamp you are going to recolor, and it becomes the active target before you choose a new color.

1. Look at the color wheel above the light and find its green segment. Tap that green segment to apply it to the selected traffic light.

1. The lamp changes from red to green. Once the light turns green, the cars move off the zebra crossing, leaving the walkway clear.

1. Grandma then walks across the crossing on her own, and the level shows the green checkmark with the completion screen once she has crossed safely.

1. Keep the select-then-color order in mind: the lamp has to be active before a segment from the wheel will apply to it, so tapping the wheel first leaves the color with nowhere to land. Choose the green segment rather than red or another shade, since only green is the pedestrian-friendly signal. After the lamp changes, let the traffic clear itself and watch grandma cross under the normal traffic rules; do not drag her onto the crossing while the cars are still held, because the checkmark appears only once the walkway is clear and she has crossed.

Strategy & Reasoning

This level combines a traffic rule with a color-painting interaction. Normally a red light makes vehicles stop and pedestrians wait, and moving grandma directly onto the crossing would put her in front of the cars. The hidden mechanism is the color wheel above the lamp: it acts like a palette that lets you change the selected light's color. Selecting the lamp first, then picking green, swaps the signal from stop to go.

The wheel contains many colors, but only green matches the pedestrian-friendly signal. Choosing red again keeps the cars held, and other colors do not produce a valid traffic light. The key ordering matters too: if you tap the wheel before selecting the light, the color has nowhere to apply. After the lamp turns green, the traffic responds naturally, clearing the crossing so grandma can finish the walk without being dragged across yourself.

Tips & Common Mistakes

• Tap the red light first to select it, then tap the green segment on the color wheel to recolor it.
• Do not drag grandma onto the crossing while the cars are still there; clear the light and let the traffic move first.
• If the light does not change, you probably picked the wheel before selecting the lamp, so tap the light and choose green again.
