提示

查看提示

Cross out the struck hints and only follow the equation that is still visible.

为什么有效

Each table is a standalone mini-puzzle. The values assigned to the letters let you work out the total in step one. Once a row is crossed out you simply stop using it, which shrinks the equation down until only the correct number remains in each of the three scenes.

常见问题

How do I solve the sequence in Brain Test 5 Level 27?

Enter 3 for the first table using the letter values, then 5 for the second and 4 for the third once the marked clues are ignored.

What is the answer to Brain Test 5 Level 27?

The three answers in order are 3, 5, and 4, one for each equation table in the level.

What is the hidden mechanic in Brain Test 5 Level 27?

Struck-through clues are dead weight; you only compute with the equation lines that are still active.

Why do I need to cross out clues in Brain Test 5 Level 27?

Removing the marked hints narrows each table to a single readable equation so only one correct number remains.

Is there a video walkthrough for Brain Test 5 Level 27?

Yes, the walkthrough runs through entering 3, 5, and 4 across the three sequence screens.

How do I avoid getting stuck in Brain Test 5 Level 27?

Work each scene separately, apply the letter map on the first screen, and always verify which clues are crossed out before computing.
