### 1/5 — Abandoned

*2024-10-13*

Looks like the dev has abandoned this game. I downloaded it months ago and it had numerous issues… buggy and IAPs are non responsive. Reinstalled it to see if the issues were resolved and it’s in the same state. Not worth trying unless the game is updated and maintained IMO.

### 1/5 — Unable to watch ads

*2024-08-25, version 4.3*

I tried to watch an ad to increase my tracks but it wouldn’t play for me. Very annoying.

### 2/5 — I can’t progress past a certain point

*2024-03-24, version 4.3*

I can’t get any of the lines past bronze because in order to prestige a line to silver you have to pay 100 gems or watch an ad. I can’t get 100 gems because all the achievements either don’t work or require me TO PRESTIGE A LINE, and the advertisements don’t load at all.. it’s impossible to fully upgrade anything

### 1/5 — Ad platform, not game?

*2022-09-03, version 4.1*

Literally five clicks into the game (upgrade, buy a subway, exit. Upgrade, buy a station) an ad. Only download if you’re looking for a quick, easy way to watch ads.

### 1/5 — This game is just an advertisement board

*2022-04-23, version 3.9*

This game sends you an ad every 30 seconds and it’s hardly even a playable game, you just tap buttons. It’s not what the picture looks like at all. I do not believe that actual people rated this 5 stars, it must have been the game creators

### 5/5 — Good

*2022-03-18, version 3.9*

It’s a really nice game to relax on, I got it today and I’m in the 4 WORLD! Get it today.

### 4/5 — Gem train

*2022-02-21, version 3.8*

The only problem I have with this game is I am unable to collect from the gem train. I read the other reviews and I’m not the only one with this problem. Please fix!

### 1/5 — EXTREMELY Bad Math!!!

*2021-10-02, version 3.8*

You guys seriously need yo work on your math skills, please!!! I am supposed to be getting 3x my leveling up bonus for watching an ad. Well sometimes I do not even get 2x the money that I am entitled to even though I have watched the ad in its entirety and exited the ad and returned to playing my game. One of my base level up bonuses was for 26.8 trillion dollars. I was being told that 26.8 x 3 was 51.84 T dollars. 51.84 is not even 2x times the amount of 26.8.  26.8 x 3 is 78.4 T dollars. There is a GINORMOUS difference between 51.84 T dollars 78.4 T dollars!!! Over 37 T dollars difference. I mean what is even the point of my watching an ad for a certain reward if I am not even going to get all of the reward that I watched the ad for to begin with?

### 1/5 — To many ads

*2021-07-16, version 3.1*

It’s not a good game when you make the first upgrade and an ad pops up and then the same for every upgrade you make.

### 1/5 — Doesnt work on iphone12

*2021-06-23, version 2.8*

The playable screen stretches too much to be playable and ads block the upgrade buttons
