📖 THE STORY

You are immersed beneath the ocean waves, surrounded by sea creatures of all shapes and sizes swimming around you. Ultimately, you have just 3 minutes to enter the mysterious small room and solve its final puzzle!

あなたは、神秘的な海の生き物や隠された手がかりに満ちた奇妙な海底世界に閉じ込められてしまいました。限られた時間の中で、パズルを解き、海の生き物を集め、脱出する方法を見つけなければなりません。

🎯 HIT THE BULLSEYE

This was our first large indoor puzzle hunt, and we thoroughly appreciated being able to concentrate exclusively on solving puzzles without the usual distractions of weather conditions that come with outdoor puzzle hunts.
We strategically divided our team, allowing Chikako to tackle puzzles requiring a Japanese speaker while we handled the English ones. Our efficiency in solving the puzzles gave us ample time to discuss all the puzzles we individually tackled before proceeding to the final challenge.
The puzzles varied, with some involving "search and find," others requiring logic, and some being phonetic. This diversity allowed each team member to leverage their strengths effectively.
We appreciated the "twist" in the final puzzle, which initially led us to believe we might fail, but a shift in our thought process turned the tide in our favor.

シンプルな謎が多いが、日本の周遊謎やホール型公演の序盤に出てくるような、紙ベースの日本的な謎解きを英語でも楽しめるのが良い。日本の謎解き文化やSCRAPの謎に慣れるための公演に適している。謎を時間内にたくさん解く構成なので、チャレンジとして面白いし、簡単な謎を数多く解くのが好きな人には特に楽しいゲーム。初心者にもおすすめできる。
店舗の指定されたエリアを回る形式のため没入感はやや控えめではあるが、世界観に沿った謎が用意されており、深海をイメージした部屋があったのも印象的だった。店舗内を歩き回りながら謎を探索するのも楽しい。
二つのパートに分かれているため、周遊謎と脱出パートの両方を味わえる構成になっているのは斬新。脱出のパートは３分と短いが、ラストの謎としてふさわしい内容だったと思う。
二つ目のパートのヒントは、とてもありがたかった。

🧩 MISSED THE MARK

The coin's "advantage" at the end was unclear. If it had a more exciting role in intertwining the storyline or added more purpose during the final puzzle, it would have been much cooler.

二つの異なる種類のゲームスタイルに分かれているため、最初の説明が長くなりがち。二つのパートの間にも説明が入ることで、ストーリーやゲームの流れが途切れてしまい、没入感はあまり感じられなかった。ストーリーの展開も特に強くはなく、二種類のゲームスタイルがうまく融合していないように感じた。
最初の３０分が探索と紙謎が中心のため、物理ギミックや電子ギミックが好きなエスケープルーム派の人にはあまりおすすめできない。

🏹 TAKE A SHOT?

This indoor puzzle hunt game offers a dynamic blend of puzzle difficulty levels, clearly marked on each puzzle. Players who understand Japanese have access to more puzzles, but the game is fully solvable for English-only players. English speakers can complete the game, though they encounter fewer puzzles. It's wise to either take detailed notes or snap pictures with your phone, as some puzzles are interconnected and not always located nearby, saving you unnecessary trips. We thoroughly enjoyed racing around the building, searching for clues, and collaborating as a team to solve them. We take pride in having collected all the coins, which aided us in the final puzzle. Do you have what it takes to escape from underwater?

「Escape from the Underwater Puzzle Challenge」は、SCRAP店舗内を回って紙ベースの謎を解くパートと、脱出パートという二つの謎解きスタイルが融合した新感覚のゲームです。日本の謎解きに触れてみたい方や初心者向けで、プレー人数は2~3人がおすすめです。SCRAP渋谷店を訪れた際は、ぜひ一問でも多く解けるようにチャレンジしてみてください！
