A puzzle you haven’t seen before. A story you won’t forget.

G30 – A Memory Maze is a unique and minimalistic take on the puzzle genre, where each level is hand-crafted and meaningful. It’s a story of a person with a cognitive disorder, who is trying to recollect the elusive past – before the disease takes over and everything will fade away.


• Each puzzle is a story. Solve the memories mystery hidden in 7 main chapters of unique and individually designed puzzles.
• Experience a touching narrative. Live the life of a person whose memories have faded.
• Feel the game. Atmospheric music and haptic feedback will dive you into the breathtaking story.
• Relax and play. No scores, no timers, no “game over”.

Each level sparks a little memory of the person’s life. It’s a two-part puzzle: a visual image of the memory and a telescopic text, that reveals itself with every step. You start with fragmented pieces of the picture and have to move them to restore the original image. In turn, telescopic text reacts to your every step – the closer you are to the solution, the more text unfolds. You are indeed remembering – adding details to the memory and forming a clear picture.


G30 is about memory and consciousness – and what they mean for a human being. There are people around who are losing their ability to remember – some kinds of mental diseases do that to a person. G30 shows how they see the world, how they feel about the past they can’t remember and the reality they can’t recognize.

Not only an incredible game, but an incredible experience.

This is the rare game that truly takes you into its world with all of your mind. Often, a puzzle game will claim to have an underlying plot, when in reality the plot is totally unrelated to the game and serves only as a distraction. This game is not like that. The puzzles *are* the plot, and they tell the story without the need for the player to ever take their mind away from the puzzle. The story itself is incredible, eschewing the traditional Western narrative structure in favor of a looping, ambient format which largely original, at least in my own experience, and which fits the tone of the game as if they were made for each other, which of course they were.
The gameplay is just as incredible, playing out in multiple layers simultaneously, with levels looping back on themselves, and a perfect difficulty gradient which kept me from ever feeling as if it was either too easy or too hard.
This is the needle in a haystack. This is a truly amazing game and a truly amazing journey, and I am so glad I discovered it.

Brilliant execution of a challenging idea

How do you replicate the fractured world of someone with memory loss in puzzle form? Well, like this. I’m not sure I’ve ever seen a better marriage of game mechanics and subject matter. As you work through the puzzles, watching words appear and disappear, you search for meaning; yet, as soon as you think you have grasped the story, it becomes a different story altogether. It’s incredibly empathetic, and I defy anyone with a soul to not experience a sense of the frustration and anxiety of not...quite...knowing who you are, and whether the pieces of your memory are even real. I get that doesn’t make it sound very appealing as a game, but it is, and a very positive experience overall.

Another perspective

This game is definitely worth the 5 stars and the amount to purchase. This is more than just a puzzle, this allows one to view life from the eyes of another. Up until I figured out and solved the entire game including the secret words I didn’t quite understand and felt lost and unsure. If I wasn’t emphatic already for those that live this life daily, Ik that my heart has swelled more with compassion for them and hope one day this dark world will have light shed on it. Now I understand why the game is called G30 a little more. Take the time to really understand this game is more than just a game.
