Until level 13 I did not need more than 2 tries (just now I played level 14, with 3 tries). The game is reallistic? No, it is a game! The author must let people know it is just a... GAME. Well, and it is not like British traffic? Hmmm, yeah, I believe it is not, but - for example - I do not live in Europe. I live in South America. Sadly it is very reallistic here, but it is not the point now.

About the game:

I think any puzzle game is a bit repetitive, but it is not so addictive like... I don't know, games with bubbles =D ...

But the graphic is good, I couldn't listen the sound because my computer have no speaker, the control is good, after you understand the game - the cars came always from the same point - you can use logic to think where the sign must go...

If you need a bit more control over random traffic, play Simutrans. If you need more realism through the city, play Sim City... If you do not enjoy the game realism, play the "real life".
