Parcel Master is a premium simulation game for PC by Error 300. It is a parcel delivery simulator experience featuring puzzle mechanics for its gameplay wherein players will be tasked with going on delivery runs throughout the city. They must figure out the best route to complete as many deliveries as they can with limited roads to take. 

Delivery run 

In Parcel Master, you assume the role of a parcel delivery operator who guides drivers in taking packages to their intended destinations and recipients. The goal is to direct your trucks on the right route that will let them pass by drop-off points while taking into consideration the limited road they will drive on. 

You will start with a small area in the city that will gradually expand to cover more ground across 100 puzzle levels, each one being more complex and challenging than the last. Having said that, there will be some players who will find the gameplay too hard as the difficulty quickly ramps up with each stage. 

Avoid gridlock 

In conclusion, Parcel Master is a deceptively simple puzzle simulator that will test the skills of even the most veteran of players. It's easy to get into yet hard to fully master, and there are a lot of levels to take on. If you are up for the challenge, give this one a try and experience it for yourself.
