Pokemon TCG Pocket leverages the Zeigarnik effect, only giving you a small preview of an unobtained card and not letting you view it on a larger scale. This is because when viewers feel they've obtained something, much of the dopamine rush that comes with actually obtaining it is already spent, often making them mentally 'check it off' prematurely. By keeping the full card just out of reach, the game maintains a sense of incompleteness and anticipation, ensuring that players stay motivated to continue collecting rather than losing interest too soon.
