Why is Solitaire addictive?

Why is Solitaire addictive? The game has a learning curve. This makes it more addictive because people can see how they improve over time and eventually want to beat their own scores. As a result, Solitaire can fuel dopamine receptors in the brain, with each successive high score providing a (theoretically) better dopamine rush.
