Brain Test 5 Level 98

Overview

This level asks you to keep a hot air balloon flying safely through two different sky scenes. In the daytime scene, a burning sun sits directly above the balloon's envelope while an airplane and a cloud float nearby, and a tree stands on the ground below. In the nighttime scene, the balloon drifts near an active volcano under a crescent moon, with the airplane still crossing the sky. The challenge is removing or shielding the heat sources that could burst the balloon before it continues its flight.

• Difficulty: Easy
• Estimated moves: 3

Step-by-Step Solution

1. Read the prompt "The air balloon must fly safely." Look at the daytime scene first: the yellow sun is resting on top of the red-and-blue balloon, and its direct heat is the main danger to the envelope.
2. Move the cloud across the sky so it covers or blocks the burning sun. Shielding the sun keeps its rays off the balloon cloth and lets the balloon stay inflated without being scorched.
3. Keep the balloon away from the airplane's flight path as well; the plane is a separate obstacle crossing at height, and a mid-air collision would be just as harmful as the heat.
4. Once the daytime balloon is clear of the sun and the plane's lane, that round settles and the night scene appears.
5. In the night scene, identify the volcano on the ground below the balloon as the new heat source. The crater and lava flow threaten the balloon if it drifts too low over the mountain.
6. Guide or keep the balloon at a safe height above the volcano, away from the rising heat and smoke, while leaving it clear of the airplane overhead.
7. Confirm the balloon is not touching any heat source or obstacle, then let it continue. When both scenes are passed safely, the level reaches its completion celebration.

Strategy & Reasoning

The balloon's weakness is heat rather than wind or landing. The sun in daylight and the volcano at night are both sources of high temperature that can damage an inflated envelope, so the safe route keeps the cloth away from both. The airplane, by contrast, is a navigation obstacle that only needs an empty lane, not a shield.

The cloud in the daytime scene is the obvious protective prop: it exists specifically to cover the sun, and without moving it there is no other way to block the direct rays. Dragging the balloon itself away helps only partially, because the sun's heat still reaches the cloth from above.

At night there is no cloud provided, so the solution becomes vertical positioning: stay high enough to clear the volcano's heat while staying below the airplane. Reading each scene's heat source before acting prevents repeating the same wrong attempt on the wrong object.

Tips & Common Mistakes

• Do not leave the sun exposed over the balloon; pull the cloud over it first to block the direct heat.
• Do not steer the balloon low over the volcano in the night scene; its lava and heat are the same danger as the daytime sun.
• Do not forget the airplane in either scene; keep a clear lane around its flight path before letting the balloon move on.
