About The Diary

The Diary is a 2D suspenseful narrative puzzle game that revolves around several distinct "diaries," including a journal full of life but full of doubts, two investigative notebooks written by different people, and the planner's diary, which will all be displayed before you.

By solving each page's puzzle, you will turn the pages and gradually gain insight into a heart-stopping missing case. From different perspectives, you will uncover the buried past behind the case.

· Open an unknown diary and search for its owner while solving puzzles

· Among 6 characters, whose perspective are you reading the diary from?

· With multiple reversals, the answer may be right in front of you or it may never appear

How much does The Diary for PC cost right now?

The Diary for PC starts at €7.55 at Difmark, 32% under the €11.05 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €8.55 at Kinguin.

That €7.55 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.

Only 3 offers across 3 stores carry it, and thin supply means the price barely moves.

Which format should you buy?

The cheapest route is a shared account at €7.55 at Difmark: you get into an account that already owns the game, but it never becomes yours. A key for your own Steam account starts at €8.55 at Kinguin, €1.00 more, and that is the sensible option.

Can you activate it in your region?

All 3 offers are Global, so the code redeems on any account no matter where it was created.

So, which The Diary deal should you buy?

For most people the key at €8.55 at Kinguin is the sensible buy: the game stays on your own account and it is only €1.00 more than the shared account.

INFORMATION ABOUT The Diary FOR PC


The Diary is a 2D narrative puzzle game centered on several different diaries, each with its own voice and mystery. Through a journal full of life but full of secrets, investigative notebooks written by different people, and a planner, the player gradually unravels a hidden story related to a lost case. Each page opened reveals more clues and advances in understanding what happened.

The game's mechanics invite investigation from different angles, organizing scattered records such as chats and exploring various elements, from photographs from the past to musical instruments and dolls that hide secrets. This variety of interactions helps piece together the puzzle and uncover key details to understand the plot.

What's interesting is that the same event is presented from multiple perspectives, forcing the player to constantly analyze and reinterpret what is known. The player must chronologically order the events and connect seemingly unrelated clues to form a coherent picture of the story, which is not always easy to decipher.

As you progress, you must think carefully and follow the character Boo's deep reasoning to resolve the questions that arise and get closer to the truth. However, not everything is clear or definitive, as the story includes twists and turns that defy expectations and maintain the intrigue.

Ultimately, The Diary offers an experience where solving puzzles and exploring different narrative voices combine to tell a mystery that may have hidden answers or even be open to the player's interpretation.

Most common FAQs when buying The Diary for PC in digital format:

It is a key that will allow you to download the game The Diary on your PC from official download platforms.
As of 02/08/2026, in United States, the best price we have found in our selection of online stores that include the key for The Diary on PC is €7.55.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download The Diary to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought The Diary, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
