## What is Alcyone?

Now, dive into chemistry!

Alcyone is a brain puzzle designed for those with a scientific curiosity. It helps those who want to learn chemistry more easily and enjoyably, while offering a challenging and engaging experience for chemistry enthusiasts. Users worldwide have already recognized its highly effective learning experience.

Build molecules and trigger reactions.

• Combine elements to synthesize a wide variety of molecules. Experience the vast world of chemistry and find joy in discovering over 1,300 real-world compounds.
• Compounds change through three phases—solid, liquid, and gas—depending on the ambient temperature. Their physical properties, where solids and liquids sink and gases rise, act as key variables in your puzzles.
• Place identical compounds in adjacent cells to trigger reactions. The more complex the elemental composition of the compound, the higher the score you earn, allowing you to find your own efficient scoring path.
• Your score increases exponentially as the number of reacting compounds grows and the chain reactions last longer. Strategize your placement to achieve the highest possible scores.
• From basic reactions like acid-base neutralization and hydrolysis to advanced organic chemistry, combine real-world chemical reactions to design and enjoy spectacular chain reactions.

Explore the periodic table and collect elements.

• Conquering numerous stages organized by atomic number, from Hydrogen (H, 1) to Krypton (Kr, 36), allows you to explore chemistry from basic to advanced levels step-by-step.
• Every time you complete a stage, you can collect new elements or unlock new chemical reactions that expand the possibilities of your experiments and your scientific toolkit.
• Upgrade each element to significantly boost your scoring efficiency. As you upgrade specific elements, the value of every compound containing them increases, letting you reach much higher scores.
• Acquire and upgrade organic functional groups to improve synthesis efficiency. Even compounds with complex structures can be created much more easily and quickly using upgraded functional groups.

Alcyone is continuously improved through regular updates. Focus entirely on the joy of chemistry without any in-app purchases or pop-up ads.

### 5/5 — Acetoacetic Acid?

*2026-08-26*

I adore this game and all its contents. It’s great for memorizing molecules and derivatives of compounds, but is there a way to make Acetoacetic Acid without it creating its isomer, Acetic Anhydride?

**Developer response:** Thank you so much for your feedback. Because the game system determines molecules based on element counts, it is difficult to represent different isomers. Although both compounds you mentioned are included in the database, only one actually gets generated in practice—an edge case I hadn't caught.

### 5/5 — Thanks for making such a great chemistry game.

*2026-08-21*

I want to start off by saying that this game became a huge time waster for me. I'm so entranced because of how every molecule reacts with one another. The hydrolysis reactions with lithium hydroxide and lithium nitrate are super cool, not to mention all of the different molecules and elements. Thank you for making such a great game and I am so proud that you released another update after almost 4 months. Thank you for such a great game

### 5/5 — 재밌어요!!

*2026-08-16*

근데 끝까지 다 깨도 별로 뭐가 없어서ㅜㅜ 끝까지 다 깨면 뭐 문구라도 나오는 창을 띄워주거나 아니면 화학 분자 도감(합성하면 도감 채워짐) 같은걸로 과거의 기록을 계속 이어갈 수 있었으면 좋겠어요ㅜ.ㅜ

### 5/5 — 学べるし、何より楽しい

*2026-08-09*

完成度が高く、色んな化合物が出てきて教育的です。パズルも楽しいので、時間を忘れてできます。また、カレンダー仕様も素晴らしいです。さらにこのゲーム独特の温度変化という機能も大変面白く、そして、レベルなど進行状況によってアンロックされる反応（縮合反応など）の機能も大変面白いです。

ただ、「ホーム画面」的な物を用意して、レベルを選択出来るようにすれば良くなると思ったのと、化合物の図鑑的な物があれば、過去に作った化合物が作りやすくなったりするかも、というのが僕の感想です。（投稿した時点では）

その点も考えた上で、現存では☆5というところです。

**Developer response:** 貴重なフィードバックをいただき、誠にありがとうございます。これまでに生成した化合物は、画面右上のスコア表示エリアをタップするか、v1.5.0以降に追加された画面下部の「統計」ボタンから開いてご確認いただけます。また、ホーム画面に関するご意見につきましても、今後のゲームモード拡張の際に前向きに検討させていただきます。

### 5/5 — Beat the game two times. Always make Asparagine or Glutamine. If you want to win.

*2026-08-07*

I really like how each element and compound has an explanation of what it does and what it spouse todo. I do hope more stages will be added in the future, as I would like to see all the elements.

### 4/5 — 점수기록

*2026-07-31*

좋긴한데 명예의 전당같이 최고기록이나 여태 만든 화합물의 횟수나 등등 기럭이 님으먼 좋겠어요. 보통 목표가 ”최고점수보다 높게하기“ 이런건데 그 최고점수가 없어서 하루만에 질렸내요.

화합물 도감같은 것도 있으면 좋겠습니다.

**Developer response:** 소중한 피드백 정말 감사합니다. 생성한 적이 있는 화합물들의 기록들은 우측상단의 점수영역을 탭하면 확인하실 수 있습니다. 최고점수에 대한 부분은 차후 업데이트에 추가하도록 하겠습니다.

### 4/5 — 作り込みが恐ろしいが、少し勿体無い

*2026-07-20*

タイトルにもある通り、このゲームの強みはとてつもなく精巧に作り込まれている点だと思う。元素一つ一つのかなり詳細な説明に留まらず、中和や酸化、凝縮反応など挙げればキリがない。遊び始めてしばらく経ってからようやく気づく要素まであるのだから恐ろしい。
　だからこそ、このゲームはもっと可能性があると考える。ここからはあくまで僕個人の意見だが、ここまで精巧に作り込まれたゲームの全貌を全ての人が見ることができないのが少し残念に思う。ゲームを進めていく途中で反応の種類を増やしていく点は非常に面白いと思う反面、初めから全て見れたら面白いのになと思うこともしばしばある。ステージを段階的に進めていくモードしかないのが少し残念だ。

　これはあくまで素人目線の提案で、開発者様の尽力には遠く及ばない戯言ではあるが、少しでも目に触れたならどうか追加してみてほしい要素が一つだけある。それが、「『サンドボックス』モードの実装」である。
　往古来今、物質と物質の反応を楽しむゲームは多く生み出されてきたが、このゲームほど精密に作られたものは無いように思う。だからこそ、もっと自由にプレイできる場を設けてほしい。具体的には、先述した通り、全ての化学変化(硝酸が水に溶けるなど、ゲームバランスを考慮してボツにした案も含めて)を詰め込み、反応を楽しむモードである。おそらくは連鎖反応も起こりやすく、より広い年齢層に受け入れられるようになると思う。

　何度も書いた通り、このゲームの基盤が恐ろしく綺麗に作り込まれているのは素人目線にも容易にわかる。あとは、ゲームの楽しみ方を少しでも増やせればより面白く、より人気のゲームになるのではないかと思う。
　先述の提案が目に触れたなら、どうかご一考を願いたい。

### 5/5 — 재밌어요!!

*2026-07-14*

퍼즐게임을 무척 좋아하지만 이제 어지간한건 다 해서 질렸던 상태였는데요. 우연히 접해서 세달정도 매일 하는데도 여전히 재밌어요! 화학은 잘 몰랐는데 하는동안 자연스럽게 어떤 원소가 있고 어떤 분자 합성을 할수 있는지 배우게 되네요. 
딱 하나 아쉬운 점이 있다면 업그레이드를 할 때 선택을 취소할 수 있는 기능이 있으면 좋겠어요! 가끔 잘못 누를때가 있어서요 ㅠ 나머지는 다 너무 좋아요~~^^

### 3/5 — 게임 리셋

*2026-07-01*

36레벨 클리어 했는데 아무 이유 없이 갑자기 1렙으로 리셋되었어요 몇주정도 키운건데 당황스럽네요.. ㅠ

**Developer response:** 안녕하세요, 현재 알키오네의 최종 스테이지가 36(크립톤)입니다. 시스템오류나 리셋이 아니라 모든 스테이지를 다 클리어해서 엔딩이 나오고 처음으로 돌아간 것입니다. 끝까지 가기가 매우 어려운데 전부 클리어하셨다니 정말 대단하시네요! 본의 아니게 혼선을 드려 죄송하며, 향후 좋은 업데이트로 보답하겠습니다.

### 4/5 — 약간아쉽

*2026-06-26*

처음 원소 창에서 조합법은 없고 그냥 발견개수만 나와서 항상 만들던것만 만들게 됨 새로운 걸 알거나 지식 획득 과정이 그냥 보통사람에게는 접근이 어려워서 좀 아쉽
