Scout doesn't work

My scout which i get for upgrade my city, open one tile and after that he walks around my territory. In every game!
Need fix it.

Consider backing up your request with a selection of screenshots?

The scout is known to not plan route ahead at all, with much backtracking sometimes.
Additionally some will never venture on water.
I only pick the scout on rather small maps with a probability for discoverable dry land nearby, otherwise I pass on the gambit and pick the workshop. The scout can bring near zero value sometimes.

But, "every game"? That's on odd claim that needs supporting material.

The explorers can only move on tiles you can. It can only move on mountains if you have climbing, shallow water if you have fishing, and deep ocean if you have sailing. If the explorers are just wandering around your territory, it is likely trapped by water or mountains without the appropriate tech. It will always target the nearest fog, and pick randomly if there are multiple within the same distance. To make sure the explorer goes in the direction you want it to, clear fog with your other units in other areas. Take explorers in forward cities to give it the best odds of discovering useful tiles.

Thanks for the clarification, wasn't aware of those scout mechanics

@onyx moth does this help with your scouts?

I've been playing a lot on island maps lately and unlocking the entire island before learning water tech. But when I first started playing, I don't remember a scout not being able to cross the ocean. And that was a problem on land maps too.

Then this. Or replays.
