Yes, they definitely can do maths! GI's intention is to tie players to the game. In first option player will be tapping fuel station every 10 minutes, in second will spend 600 coins for additional 20 units of fuel (it's not a business in IMHO too). Spending quite large amount of coins will force player to visit the game more often to regain spent coins. So in first or second option player will return to the game frequently and the goal is achieved
For the record: I'm not a GI employee![]()
GI certainly don't have issues with their maths when it comes to making money (real money) from its clients. I was just at one of my favourite app review and news sites (where we wanted to advertise some of our own apps, so I know the rates), and they [GI] have taken the most premium position (the rate card is at US$60/month) on the site for their latest game.
