### 5/5 — Incredible 3D game

*2026-05-04*

Great game to think a bit about geometry in 3D!

### 5/5 — Wonderful Geometry

*2026-02-03*

A fun way to practice and visualize 3D geometry. Think in terms of points, lines and planes, solids and projections. Good practice for anyone interested in visual geometry, art illustration, drawing, CAD design, math and science. Great brain exercise.

### 5/5 — Лучшая в AppStore

*2026-01-30*

Отличная увлекательная головоломка для любого возраста. Дабы не отупеть от соцсетей всем советую скачать и потренироваться. Сам перепрохожу периодически. Из игр схожего направления на мой взгляд одна из лучших(хотя и давно на пенсии), если не лучшая!

### 5/5 — Pretty good

*2025-11-03*

Thanks for it

### 5/5 — Топ

*2025-10-14, version 1.10*

Очень классная игра, удобный интерфейс, есть глосарий

### 5/5 — The best app I ever used to keep my brain exercised.

*2025-01-26*

From idea to execution it is a brilliant project, love all other apps of this company. Great job!!!👍🏻💕

### 5/5 — 100th rating, Yay!

*2024-11-27*

Love this game and all your others.  I’m craving more!!!  Update- Please make more!  I rarely buy games but would gladly pay for more levels of this game!  ❤️

### 5/5 — So good! Wish there were more puzzles

*2024-05-13*

This is such a unique idea for a game. I love the way that being stuck in 2D requires you to really think about where your lines and points are in space. The game UI, while subtle, is very cleverly designed. It provides enough info to disambiguate any uncertain constructions. Even if you are good at visualizing the solution in your head, actually constructing it from known points/lines can be quite challenging!

It’s always a treat to come back to this game to complete all the puzzles again. When I take a long enough break I become rusty enough that some of the puzzles are still a challenge. But I really wish more hard puzzles could be added! They’re so satisfying to complete; and there’s no other game like this!

### 5/5 — Love it

*2023-08-27*

Drawing is intuitive; there are no drawing tools. I want more puzzles.

### 5/5 — 648936
