Brain Test 5 Level 45

Overview

A flag stands on top of a high structure or ledge, and the only way to reach it is to climb and stack the wooden crates provided on the ground. The solution is to build a crate tower step by step, then climb it to reach the flag rather than jumping from the floor or looking for a hidden ladder.

• Difficulty: Regular
• Estimated moves: 3

Step-by-Step Solution

1. Look at the flag high above and count how high it sits, then locate the loose wooden crates on the ground that will form the climb.
2. Stack the first crate on the ground directly beneath the flag, setting it level and steady so it can support the next crate.
3. Add the remaining crates one at a time on top of the stack, building the tower upward until its top reaches the height of the flag platform.
4. Climb the stacked crates to the top once the tower is tall enough, stepping up from crate to crate toward the flag.
5. When you reach the flag at the top of the crate tower, the checkmark appears and the level completes.
6. Stack each crate squarely on the one below it, centered under the flag, so the tower stays straight and gives a solid step at every level.
7. Climb only after the tower reaches the flag platform's height; a too-short stack leaves you jumping from the top crate, and the checkmark appears once you reach the flag at the top.
8. After reaching the flag, confirm the crate tower still stands beneath you; the level clears on the climber at the flag, and the stacked crates remain the structure that got him up there.

Strategy & Reasoning

The level is a stacking-and-climbing puzzle. The flag is too high to reach from the floor, and no ladder or stairs are supplied, so the crates themselves become both the steps and the height gain. Each crate has to be added to the stack rather than placed scattered on the ground, because only a vertical tower closes the gap to the flag.
Stability matters as much as height. A crate dropped crookedly on the stack does not give a solid next step, so the tower should be built straight beneath the flag. Adding crates in order from the ground up prevents trying to climb an incomplete pile. This also rules out jumping straight for the flag or searching the surroundings for another prop; the loose wooden crates are the intended climbing material. The finished state, with the stack reaching the flag and the climber up on top, confirms the tower was built to the correct height.

Tips & Common Mistakes

• Stack the crates vertically beneath the flag; scattered crates on the ground do not form a climb.
• Add each crate level and steady before climbing or adding another, so the tower does not tilt.
• Do not jump from the floor for the flag; build the crate tower to the required height, then climb it.
