玩家需要利用視覺上的錯覺來製造現實中不能發生的幾何現像以協助主角到達終點。很抽象對吧? 不要緊，看一下這個例子你就會明白了。

> You have to make use of optical illusions to produce some geometrically impossible 3D figures, so as to assist the character to arrive at the destination. Quite abstract isn't it? Never mind, you will be able to understand by taking a look at the following example.

主角一開始根本不可能到達終點，但玩家在扭動路段的其中一部分之後，便由於錯覺的緣故，形成了一個可到達終點的路線。

> The character is impossible to arrive at the destination at the first sight. However a twist on the road can produce an optical illusion, so that a possible route has formed for the character to arrive at the destination.

<h2>個人評價 My review</h2>

畫面及音效非常好，控制亦很簡潔。最值得稱讚的地方當然就是其創意！

> Great graphics and sound effect. Simple and user-friendly control. Of course the best thing of this game is its creativity!

在數學上其實也有不少人提出過這一類的幾何圖案，就如以下例子在現實的三維世界根本不可能存在。但怎會想到這個概念可以放到遊戲當中呢！

> In the field of mathematics, some people have suggested geometrically impossible 3D figures like those appearing in the game, for instance the pictures shown below. But who can think of incorporating this idea into a mobile game!

因此非常建議大家玩這個遊戲，就算不是免費也值得買呢！

> Therefore I strongly recommend this game, even if it is not free of charge, it is still worth buying!
