What does it mean to "play with some aspect of the game changed"?

The phrase "play with some aspect of the game changed" refers to adjusting or modifying the standard game rules or state in a way that alters how the game functions. The correct interpretation of this phrase aligns with using special rules that deliberately modify how the game is played.

Playing with some aspect of the game changed may involve implementing house rules or alternate formats that introduce variations, such as special game mechanics, rule adjustments, or unique win conditions. This interpretation directly relates to the general idea of changing the game state to create a different experience from the standard gameplay.

The option regarding keeping certain cards face up is not representative of actually changing the game state in a meaningful way. It's more about visibility and transparency for strategic reasons but does not inherently alter the fundamental mechanics or rules of play. The other options center around either strict adherence to original rules or playing without modifications, which do not reflect the spirit of making intentional changes to how the game is experienced.
