## What is kubic?

***** #1 Puzzle Game in over 20 Countries! *****

***** "This quirky puzzle game bends the limits of space and reality to make you create structures that, in theory, should be impossible to replicate." - Pocket Gamer 8/10 *****

***** "As soothing as it is challenging, this grown-up puzzler opened our minds. Time flew by as we recreated sculpture after sculpture in increasingly difficult configurations. The game’s 3D graphics invite focus and sharpen problem-solving skills, making it an entertaining brain-builder. M.C. Escher would be impressed by the twisty, physics-defying structures." - App Store Notes *****

kubic is a unique optical illusion puzzle game based on M.C. Escher's art, impossible objects and other geometric designs. The object is to construct the goal configuration from a number of pieces.

Presented in a simple, clean design and minimalistic art, kubic is a premium game with over 60 escher-esque puzzles.

When you click on a piece, it pops to the front-most layer, and may overlap other pieces. When you combine the pieces, they do not merge. If there are extra pieces, you may hide them behind the others. You can also lock layers and drag pieces without changing their layer order. You can also use two finger pinch to zoom in and out and drag the view for a better control.

If you are stuck on a puzzle you can simply skip it and re-visit at a later time. Rest assured, all puzzles can be solved but beware, some puzzles are hard! Just take your time...Tip: It helps to plan ahead and build figures from back to front.

If you truly get stuck, there is a in-game hint system. You can use it to get started or even get the whole puzzle solved.

Levels divided in 6 groups:
• Ocean - "2D"  Shapes are basically two-dimensional arrangements.
• Desert - "3D"  Shapes appear to be three-dimensional, but remember to think in two dimensions.
• Mountain - "Convex/Concave"  These optical illusions are inspired by Escher's famous "Convex and Concave" lithograph.
• Sky - "Up/Down"  These optical illusions are inspired by the Penrose Triangle featured in Escher's lithograph "Waterfall”.
• Escher - Based on letter designs that spell out MC ESCHER.
• Print - Based on the printable magazine version of Convex-Concave puzzles.

Kubic is localized and supports 12 languages including English, French, German, Italian, Japanese, Korean, Chinese (simplified), Chinese (traditional), Portuguese, Russian, Spanish, and Turkish

Game supports iCloud for progress syncing between devices.

Convex Concave puzzles from the Heaven and Earth game are included with permission. The puzzles were designed by Scott Kim, Puzzlemaster (scottkim.com), and the Heaven & Earth team.

Enjoy!

### 3/5 — Good game but

*2025-10-17, version 3.3*

I am deducting 2 stars because it is near impossible to keep tiles in place. I figure out answer but then spend an hour trying to get the tiles to meld.  Fix and maybe I’ll come back.

### 5/5 — 有创意

*2025-10-09, version 3.3*

自己拼拼不好，看了提示会眼前一亮，很有意思！

### 1/5 — Zero Difficulty Curve

*2025-05-25, version 3.1*

early puzzles are braindead easy, later puzzles are some of the most mean-spirited ones I’ve ever encountered in any game, intentionally designed to force you to watch ads for hints. pathetic waste of time.

### 1/5 — ムズすぎ

*2025-01-01, version 3.1*

ただただイライラする🗑👋🏻ゲー

### 3/5 — Good Game

*2024-09-22*

It’s fun when to play but the difficulty ramp makes it to hard after the first like 10 levels

### 1/5 — So bad

*2024-07-16, version 3.1*

I like puzzle games but this one isn’t the one for me. because when you try to stick a block together to another block, it sometimes goes up instead of sticking together. It’s so annoying. stresses me out. not relaxing, stressful, please fix this then the blocks will actually not go up away from the other block “oh oh I wanna go up so I can stress this player out lol” 😭😡

### 1/5 — Ad Filled

*2023-06-03, version 3.0*

Under a minute of gameplay per 30 second ad. 

Not worth your time.

### 5/5 — 単なる積み木パズルでは無い

*2023-04-24, version 3.0*

最初は見本に表示された形になるようブロックを組み合わせるゲームなのですが、途中から明らかに邪魔なピースがあったり（でも使い切らないとクリアにならない）、表示が変に見える（凹んで見える）ピースが登場して一筋縄で行かなくなります。
クリア方法はネタバレになるので自分でプレイしてみて下さい。
広告頻度はそこそこですが５秒程度見ればスキップ出来るので、人によってはそんなに気にならないかも。

### 1/5 — Shameful

*2023-03-31, version 3.0*

You actually lied to people. Asked them to give you money and swiped the rug at the last second. But what do you care if everyone deletes the app? We’ve already paid you.
Disgusting.

### 3/5 — Cool game

*2022-04-22, version 2.04*

Cool game. Well realized but too many ads immediately in your face. More ads than gameplay means uninstall right away. Shame.
