Nero 2000 is a trivia quiz game released in Finnish only. You choose to compete in four question categories, each including approximately 500 questions.

The categories are:

Sports, dialect words and foreign words
General knowledge, geography and literature
Travel, literature, general knowledge and nature
General knowledge, art and movies

The game can be played against the computer AI or a human opponent on a shared computer. Answers need to be typed on a keyboard. The game proceeds in turns.

The game can be won in two ways. One is to get all the points from your opponent and another way is to get all ten "correct answer" -markers (light bulbs on Commodore version) lit before your opponent does so. These markers are lit whenever you answer a question correctly, unless you choose before seeing a new question to attack your opponent and try to black out one of their markers with your correct answer instead. In a single player game, the AI opponent never answers a question, but gets a marker lit whenever you answer incorrectly.

Both players start with 100 points and they may choose to bet any number of the points before a question is revealed. This amount of points will be stolen from your opponent upon a correct answer and lost when the answer is incorrect. There is also a randomized bonus multiplier of 2 to 4 to the initial bet, which is given to the winner, but not reduced from the loser's points. Running out of points will end the game as well.
