Brain Puzzle 3 Level 137

Overview

Level 137 is a timed classroom-and-graduation puzzle. The yellow banner says "Help students keep good graduation memories" with a 3:00 countdown. The opening shot is a messy Japanese classroom: a green chalkboard, a wall clock, a teacher's desk holding a pink cherry-blossom yearbook, a grey corner locker covered in stickers, large windows showing bare winter trees, and four students at their desks — a boy reading, a blushing boy clutching a pink love letter, a girl with glasses and braids flipping a sparkling photo album, and a boy asleep on his desk. The floor is littered with paper and trash. The goal is to prepare the class for a proper graduation memory, ending with a group photo in front of the school under cherry blossoms.

• Difficulty: Regular
• Estimated moves: 5

Step-by-Step Solution

1. Open the yearbook on the teacher's desk. Tap the pink cherry-blossom book lying on the teacher's podium. It flips open to a spread, marking the start of the graduation-yearbook ritual.

1. Let the glasses girl write on the chalkboard. Tap the girl with glasses and braids. She gets up, walks to the green chalkboard, and writes "卒業おめでとう!" (congratulations on graduating) with little hearts and cartoon drawings of three graduates. This decorates the room for the occasion.

1. Open the corner locker. Tap the grey locker in the corner. Its door swings open, revealing it is empty inside; clearing it out is part of tidying the room before the photo.

1. Exchange the love letter / photo. The blushing boy in front is clutching a pink envelope. Tap him so he hands over the envelope, which turns into a small framed photo being passed between desks; hearts float around the students as the exchange happens.

1. Change the window view to cherry blossoms. Tap the window. The bare winter trees outside dissolve into pink blooming cherry blossoms, matching the subtitle "Cherry blossoms in graduation season are the most beautiful."

1. Move outside for the group photo. Once the classroom is prepared, the scene cuts to the front of the school building. A white towel hangs on a cherry branch, the green-haired teacher in a suit sits center, and the students arrange themselves — the glasses girl crouches at the bottom painting / arranging photos on the ground. The final subtitle reads "I'm still so young and beautiful," and the red "Completed" banner drops over the finished group photo with confetti.

Strategy & Reasoning

The level is a "tidy up and set the mood for graduation" puzzle. Nothing bad is happening; the students are simply still in a messy winter classroom, and the memory will not feel like graduation until four things change: the yearbook is opened, the board is decorated, the locker is cleared, and the window shows cherry blossoms. Each tap transforms one element, and once all four are done the class automatically moves outside for the portrait.

The love-letter boy is a small side beat: tapping him turns his nervous pink envelope into a passed photo, which is the kind of keepsake exchange that happens on graduation day. The sleeping boy on the right does not need to be woken — he simply disappears into the group photo later. The trash on the floor is cleaned up implicitly as the scene cuts.

There is no failure state and no antagonist. The only wrong move is trying to take the photo before the room is ready: if the group-photo scene does not trigger, check that the board, locker, yearbook and cherry-blossom window have all been changed.

Tips & Common Mistakes

• Mistake: tapping the asleep boy. He does not need waking; he is just a background student who joins the photo later. Focus on the yearbook, board, locker and window.
• Mistake: forgetting the chalkboard. The glasses girl must write the graduation message on the green board. If the scene will not cut outside, tap her desk / the board.
• Mistake: leaving the locker shut or the window bare. The grey corner locker must be opened and the windows must show cherry blossoms before the group photo triggers. If either is unchanged, tap them.
