I came across this information and I thought I should share :)
As a Nigerian citizen, there are certain countries which do not require a visa upon entry so long as you have your passport. However, for some of these countries, there is an estimated amount of time you are expected to spend before a visa will be demanded for. The period of days for which you can stay varies from country to country and then you would have to obtain a visa. There are also some other countries that you can visit and you’ll receive a visa upon arrival. Find below a comprehensive list of these countries classified according to their continents.

I believe this list has changed: Macau I know has different rules. I see that many Caribbean nations have easy entry but actually getting there by plane often involves going via UK, etc. which makes it hard.
Oceania isn't a country or territory??
In Laos there is change policy.if u try you be returned
