## What is Crowd sourcing traffic lights?

Play and help the city to get rid of traffic jams!
Do you remember having to stay at the intersection on red for too long or being stopped at every traffic light?
If so, this game is definetly for you. Choose an intersection and take control of it. You will be setting up real intersections, no fictions.
The first three intersections are FREE!
- Change the priority signs and adjust the duration of the red and green signals at the intersection to unload roads and get rid of congestion.
- Install new traffic lights and road signs to achieve better performance.
- Change the configuration of the traffic light (for example, add an additional sections) to make traffic easier.
- make two intersections connected in a green line so that cars are able to pass without stopping at red - this will reduce congested sections.
When your result appears in the top rating, we will be able to affect the real traffic: we transfer the best results to local authorities.
We guarantee pleasant bonuses.
By now you are suppose to stop complaining and to take part in the traffic control. All this in the form of a game!
It's simple: choose the intersection of interest on the map and start.
If your intersection is still being worked out, you can speed up the process: make a donation to give us additional motivation to prepare it!
We have already worked out all the most important intersections in Kharkov, Ukraine, in the near future we are launching new intersections for Kiev. We constantly update the database and add new ones.
Try to set up the perfect intersection.

### 1/5 — I don’t get this

*2026-03-26, version 2.13*

I don’t understand what’s free. Everything I click I basically have to donate to get it like. Not everyone has money. Every city a click donate this. Nothing is free.

### 1/5 — Achtung

*2025-05-29*

Lieber nicht runterladen.
Man wird aufgefordert zu zahlen (spenden), was totaler schwachsinn ist.

### 1/5 — hardly a game or I’m confused

*2025-05-24, version 2.13*

it’s not clear what you can do, you just tap the screen and hope for the best, you don’t control the flow of traffic, there’s no crashes . it’s just unplayable. i thought this would be like traffic lanes 2 but i couldn’t have been more wrong. it would be good if it was playable but it just isn’t

### 1/5 — Junk

*2025-03-22, version 2.13*

Junk

### 2/5 — Unfortunate

*2025-01-16, version 2.13*

Game has great potential here - I can see it be an amazing simulator, but it just is not there yet. Upon entering one of the many “unfinished”/ unavailable levels you get an ad for donation, which to escape you have to restart the app. The “play for free” text is not a button and confusing…? The few maps that are competed are buggy, clicking on lights is useless and traffic is insanely quick and builds up in seconds. It crashed multiple times when I clicked on the lights to… presumably change the flow of traffic - yeah, I had 0️⃣idea of what was going on - if only there were instructions. Lots to improve on, but good concept / idea and decent start. Don’t give up.

### 1/5 — Horrible and unfinished

*2024-07-27, version 2.13*

This game could of been great but why do I need to donate? Y’all could of just made the game cost money instead of making it free. Also, the game is buggy and crashes a lot. Yeah I ain’t paying for anything until y’all fix this but I doubt it will never be fixed

### 3/5 — Как играть? Где перекрестки брать?

*2024-07-14*

??

### 1/5 — Not worth your time

*2024-01-14, version 2.13*

This game can be played. That it it crashes every time I start to play, can’t even tap the screen.

### 1/5 — This game sucks!

*2023-12-27, version 2.13*

It dosnt even work! Don't download this game it's a piece of junk!

### 5/5 — Мега идея!

*2023-11-09*

Кристина, прошу, вернитесь к игре! Это единственная наполненная смыслом игра среди игр этого класса. Да ещё и со связью с реальными перекрёстками. У меня игра вылетает. Готов внести донат если она будет работать.
