Brain Test 5 Level 41

Overview

A sleeping T-rex lies in a volcano scene, and the task is to wake it using the geyser and the rocks available around the volcano. The solution combines the erupting geyser's force with the rocks to rouse the dinosaur, rather than tapping the sleeping reptile directly.

• Difficulty: Hard
• Estimated moves: 3

Step-by-Step Solution

1. Survey the volcano scene and locate the sleeping T-rex, the geyser vent, and the loose rocks scattered nearby; these are the props that will produce the wake-up.
2. Prepare the geyser so it can erupt, positioning or clearing its vent so the water or steam can shoot upward with force.
3. Use the rocks in combination with the geyser, such as placing them where the erupting geyser can lift or hurl them toward the sleeping dinosaur.
4. Let the geyser-driven rocks reach the T-rex and jolt it awake, repeating the geyser action if the first burst does not rouse it.
5. Once the T-rex has been woken by the geyser and rocks, the checkmark appears over the volcano scene.
6. Set the loose rocks where the geyser's upward burst can lift or hurl them; rocks resting away from the vent will never reach the sleeping T-rex.
7. If the first eruption does not wake it, send the geyser again with the rocks still in its path, since the checkmark appears only after the dinosaur is visibly roused by that combined eruption.
8. Once the T-rex wakes, leave the volcano scene props where they are; the checkmark marks the awakened dinosaur, and no further interaction with the geyser or rocks is needed.

Strategy & Reasoning

The level pairs two environmental props to wake the dinosaur: the geyser supplies the erupting force, and the rocks supply the physical impact. A geyser alone might only spray past the sleeping T-rex, and loose rocks alone have no way to reach it, so the intended solution brings the two together rather than treating either as a standalone wake-up.
This is another scene where tapping the target directly fails. The T-rex is shown asleep, but the level checks that you used the volcano props to disturb it, not that you poked its body. The rocks have to be moved into the geyser's path so the eruption carries them; simply dropping them beside the dinosaur does not create the jolt. Reading the volcano layout first helps place the rocks where the upward burst can lift them toward the sleeping animal. The finished state shows the T-rex awake after that combined eruption, which confirms the geyser and rocks both registered in the wake-up.

Tips & Common Mistakes

• Do not tap the sleeping T-rex to wake it; the level wants the geyser and rocks to do the rousing.
• Place the rocks where the erupting geyser can lift or hurl them; rocks left beside the dinosaur will not jolt it awake.
• Combine the two props rather than using one alone; the geyser provides the force and the rocks provide the impact.
