## What is Cogs?

Cogs is a multi-award-winning puzzle game where players build increasingly complex machines using sliding tiles 3D. Originally launched in 2009, we completely remastered Cogs from the ground up in 2025 to look beautiful on modern phones and tablets.

"One of the highest quality puzzle games we've seen." – PocketGamer

"A masterpiece visually, as well with the actual gameplay." – AppAdvice

INVENTOR MODE
Starting with simple puzzles, players are introduced to the widgets that are used to build machines — gears, pipes, balloons, chimes, hammers, wheels, props, and more.

TIME CHALLENGE MODE
If you finish a puzzle in Inventor Mode, it will be unlocked here. This time, it will take fewer moves to reach a solution, but you only have 30 seconds to find it.

Take your time and plan ahead. Every tap counts when you only get ten moves to find a solution.

### 5/5 — Love the puzzles

*2026-07-08, version 2.0.12*

I bought this to help support the designer, since I am loving and playing all the archives of Uncrossy. I like these puzzle games, so I thought I’d purchase. My only beef is that I can’t get to all of the levels for the full price of the game. It takes me time and many moves to solve, sometimes days to solve one level I have to go back to. What I cannot do is go back in and play them fast enough or with fewer moves in order to get more stars to get to more levels. I’m stuck. I’m annoyed, but love the game. It’s a barrier I don’t appreciate in the game. Is there a cheat code or a way to unlock all the levels no matter the stars?

### 5/5 — Glad it’s back

*2026-01-18*

I’m so glad this game is back on the App Store. I bought it a long time ago and completed it. Last year when I wanted to replay it, I found that it didn’t have a reset option, so the only thing I could do was delete it and then reinstall it. However, after I had deleted it, I found it was no longer available in the App Store. So I was absolutely scuppered as i could no longer download it! Just by chance I searched for it again today and found that it’s back! It’s an intriguing yet soothing game to play, made even better by the lovely graphics. It would be great if a reset button could be added, but in the meantime, please don’t disappear from the App Store again

### 5/5 — Починились.

*2025-06-05*

Починили. Правда, картинка стала бледнее и будто в расфокусе. Раньше графика была лучше. И весь прогресс обнулился. Грусть.

### 5/5 — Best game ever(but it doesnt work :)

*2025-06-01, version 2.0.2*

We are waiting for it so loonngg time. Pls update the game to make it live

### 1/5 — It does nothing

*2025-05-28*

I tab “Inventor Mode” and see a gear. That’s it. iPhone 15, iOS 18.5. Same on my iPad Air (11 M2).

### 1/5 — Version 2.0.0 cassée (update: 2.0.2 toujours cassée)

*2025-05-21*

Elle reste bloquée indéfiniment sur l’écran de démarrage (avec un diaphragme fermé).

Update: malgré la release note qui semble dire que le bug est réparé, la version 2.0.2 bloque toujours, de la même manière.

### 1/5 — Still freezing

*2025-05-20, version 2.0.2*

Are you disabled? After another update the app is still not working. iPhone and iPad. All updated and everything is working fine except for this app.

### 5/5 — A pensar!!!

*2025-05-20, version 2.0.2*

Me encanta y lo mejor es picarse para hacerlo en tiempo oro

### 3/5 — Need to make levels Similar to free version

*2021-09-07*

I like the free version better thenThe paid version paid version guitar really quick and it makes you not wanna play it anymore so I feel like I wasted money you guys need to make it equal to the free version

### 5/5 — 子供でも大人でも楽しめる

*2019-12-31*

難易度は色々なので、子供でも楽しめます。
試しに1歳の子供にはやり方教えたところ、イージーなステージは普通に楽しんでやっていました。コレはもちろんパズルなんですけど、エネルギーがいろんな形をとって伝達していく感じが表現されてるのがいいんです。動力源からエネルギーの伝達経路作ってあげて、なんらかの仕掛けを動かす、というよりコンセプトがいいです。
