What do the angry faces mean?

The red faces mean the customers are unhappy about too few seats and/long lines in your park. Upgrade your rides and queues to fix this. The green faces mean there are not enough toilets. Add toilets to your park.

This mad face means long lines or few seats, and puke face means that YOU NEED MORE TOILETS! Mine are level 80 and I still get them!!!

I only see sick faces when I choose the ‘speed up’ option. I guess the extra speed on the rides makes people sick

On the original roller coaster tycoon for the PCs, green faces meant the guest was sick. They would actually throw up too. Had to have staff for keeping the park clean or there would be a huge mess by the exits of high nausea rates rides. Ahhhh....good times!!! Lol! :-)

I really don't think that has to do with bathrooms. The original roller coaster tycoon for PCs had green faces and it meant the guest was sick...they would actually puke on the ground. Had to have clean up staff to keep it clean or it would get terribly messy by the exits of high nausea rates rides:-)

They mean you need more seats less long lines and more upgrades

Red faces mean there is not enough seats on a ride or the lines are to long so they leave the park
