Brain Out Level 131

Overview

The prompt references the 26-letter English alphabet and asks how many letters remain after ET left. The surface arithmetic subtracts two letters for E and T, but the joke plays on the movie reference: ET departed in a UFO, so the letters U and O left with him as well. The answer entered in the field is 21.
The prompt names the ET reference directly, which hints that the answer depends on a familiar movie image rather than plain alphabet subtraction.

Step-by-Step Solution

1. Read the wording as a riddle rather than plain subtraction. The alphabet has 26 letters in total.
2. Remember the ET reference: the alien left aboard a UFO. Treat that vehicle as another group of letters that departed along with ET.
3. Remove E and T for the alien, then remove U and O for the UFO that carried him away.
4. Compute 26 minus five letters and enter 21 in the answer field.
5. Confirm the answer. The level accepts 21 once the UFO letters are included in the departure.

Start from 26 total letters and picture how ET leaves the scene: he departs aboard a UFO, so those vehicle letters leave along with him. Subtract E and T first, then remove U and O as the UFO that carried them away, giving five letters in total. Type the remaining count, 21, into the field and confirm. If your first instinct gives 24, you have only removed the two alien letters and forgotten the UFO group that left with them.

When you enter the answer, type the single remaining count rather than trying to spell out the letters that left. The pun depends on the UFO image, so if your reasoning stops at E and T you will land on the wrong subtotal; include the vehicle letters and the 21 total will match what the level expects.

Strategy & Reasoning

Brain Out riddles often hide a second meaning inside the sentence. Literally subtracting E and T gives 24, but that ignores the well-known image of ET leaving in a UFO. The riddle expects you to connect the movie reference to the word UFO, so those three letters count as leaving too. The five removed letters leave 21, which is the pun answer the puzzle rewards. Riddle levels in Brain Out hide a second meaning inside the wording, and here the movie reference supplies the extra departing letters. The pun works because ET and the UFO are tied together in the familiar image, so counting only the two named letters misses the joke the puzzle rewards.

Tips & Common Mistakes

• Do not stop after subtracting only E and T; the UFO letters also leave the alphabet.
• The answer relies on the movie reference, so picture how ET departed rather than counting letters alone.
• Enter the final count 21, not the 24 you would get from a plain two-letter subtraction.
