Brain Test 5 Level 99

Overview

Level 99 takes place in an office across two rounds. The first shows a frustrated man at a desk who cannot remember his password, with a pinned note showing digits and slips of paper tucked in the drawer, plus a numeric keypad below the screen. The second round shows the same man holding a plate of lunch in front of a dirty microwave, with a small battery cell on the counter and the workstation computer beside him. Each round asks you to recover a missing piece of information or power before the everyday task can be completed.

• Difficulty: Regular
• Estimated moves: 5

Step-by-Step Solution

1. In the password round, read "He can't remember his password." Survey the desk for written clues before pressing any keypad button: the pinned note on the wall carries the main digit sequence, and two slips rest partly pulled from the drawer.
2. Read the pinned note carefully; its three-digit sequence is the remembered clue the man wrote down for himself. Compare it with the slips in the drawer to decide which numbers are part of the actual entry and which are loose fragments.
3. Enter the correct digit sequence on the 0-9 keypad, one digit at a time. Press the keys shown by the matching note rather than combining numbers from every slip on the desk.
4. Submit the entry once the full sequence is typed. If the red cross appears, re-check which note belongs to the password and correct the digit order; the green check appears when the combination is accepted.
5. After the password round clears, the lunch round begins. Read "Help him heat his lunch." Notice the microwave on the counter has green slime inside its cavity, so it cannot be used while dirty.
6. Clean or clear the slime out of the microwave cavity first so the lunch can be placed inside without contamination.
7. Pick up the battery cell lying on the counter and use it to supply power to the microwave, matching the battery contacts or compartment the appliance expects.
8. Place the plate of food inside the cleaned, powered microwave and run it to heat the lunch. Once the meal is warmed and the round clears, the level moves to its completion screen.

Strategy & Reasoning

The password round is a clue-gathering puzzle rather than a guessing lock. Several numbers are visible on purpose, but only the note matching the login belongs to the entry; treating every slip as part of the code produces a wrong combination. Reading the prominent pinned note first narrows the candidates before the keypad is touched.

The keypad gives immediate feedback through the red cross and green check, so a wrong entry can be corrected by going back to the notes instead of retyping random digits. Order matters as much as the digits themselves, so the sequence should be entered from left to right exactly as written.

For the lunch round, the two blockers are condition and power. The slime makes the microwave unusable until the cavity is cleared, and the battery cell on the counter is the missing power source the scene provides. The computer tower on the desk is unrelated to heating the food and should not be tapped for this round.

Tips & Common Mistakes

• Do not combine digits from every paper on the desk; only the matching note's sequence is the password clue.
• Do not skip cleaning the slime out of the microwave before putting the lunch in, or the appliance will not heat the meal properly.
• Do not leave the battery unused; the microwave needs that cell from the counter to run.
