This is also in line with other earlier findings presented in the introduction to this paper. In the context of card games, particularly those with limited strategic or tactical options (not implying that UNO lacks strategic depth), research findings suggest that the visual design should prioritize supporting the social dynamics of the game, particularly player communication, as this has a significant impact on the overall player experience, as outlined in earlier research [21; 22; 23; 24; 25]. As shown in Table 7, the visual impression in the digital version of UNO is shaped by 3D graphics, animations, visual effects, user interface design, and customization options. The results shown in Tables 8 and 9 indicate that the visual impression is significantly higher for the physical version than for the digital version. This may be attributable to the presence of numerous visual elements that could divert players' attention from the gameplay. Colors also emerge as a significantly distinct element in Table 9, likely due to the increased number of color options available to players. Furthermore, the results in Table 8 reveal a higher degree of variability in responses related to colors in the digital version of the game, which may indicate more polarized opinions on the color scheme (either highly positive or highly negative). This implies that additional research is welcome to better understand these differences. As outlined in Table 7, the screen size may limit the visibility of played cards due to certain card placements, which could help explain the results presented in Tables 8 and 9. This limitation may suggest a deficiency in the user interface design, where animations and effects are prioritized. However, given that animations received the highest ratings of all observed elements in the digital version, it appears that while animations are generally well received, their placement or space usage within the interface may require optimization. Further analysis indicates that the quality of the user interface is rated relatively high (Table 8), suggesting that users generally perceive it favorably. The lowest-ranked element in the digital version (Table 8) was immersion, which, when compared to the physical version, revealed a statistically significant difference. Given the relatively positive evaluation of the user interface design, the most substantial difference between the two versions lies in an area beyond visual aesthetics: the absence of tools for direct player communication. The lack of face-to-face communication reduces key elements of fun--an essential characteristic of social games [16; 24]--such as narrative, player teasing, provocation, humor, and other relationship-building and emotionally engaging forms of social interactions. This element significantly contributes to the appeal of these games and situates them within a unique social context, particularly in terms of immersion. Furthermore, if properly incorporated, it could reduce downtime or optimize other time-dependent aspects of the game mechanics. In addressing the limitations of this research, it is essential to acknowledge that the results are derived from survey data reflecting players' overall perceptions of specific aspects of the examined games. These perceptions were subsequently analyzed in relation to the fundamental differences in the visual design of various game elements. Consequently, it is difficult to ascertain the precise impact of differing levels of personalization of these elements on the observed outcomes. To achieve a more nuanced understanding of how visual element personalization affects gameplay, a more comprehensive experimental study would be required. Such an investigation would need to isolate individual elements and their varying degrees of personalization, a scope that extends beyond the current study. Nonetheless, the findings presented here could serve as a solid foundation for future research in this area. Finally, the issue of identity representation emerges as a relevant consideration when interpreting the results.
