Adults in Spain are increasingly turning to new hobby books like Murdokus and Murdles instead of traditional crosswords and sudokus this summer [1].
This shift reflects a growing interest in cognitive wellness among older populations. By diversifying the types of mental exercises used, adults can better engage different areas of the brain to maintain mental agility.
The trend is particularly prevalent among individuals over 60 years old [2]. These users are seeking mental leisure activities that offer a fresh challenge compared to the repetitive nature of classic puzzles. The new wave of "summer notebooks" for adults focuses on memory, concentration, and logic [2].
La Sexta said these specific titles have become the star pastimes of the season [1]. The books are designed to train the brain through a variety of logic-based challenges, which differs from the vocabulary focus of crosswords or the numerical patterns of sudokus.
Cognitive wellness studies suggest that maintaining an active mind is critical for aging adults [2]. The adoption of these new formats allows users to practice deductive reasoning and pattern recognition in more narrative or complex environments. This variety is intended to help keep the mind active and prevent cognitive stagnation [2].
While traditional puzzles remain available, the surge in popularity for Murdokus and Murdles indicates a market shift toward more modern, gamified versions of brain training. These materials are being distributed widely across Spanish-speaking media and retail outlets as the preferred choice for summer leisure [1].

The transition from static puzzles to more dynamic logic books suggests a broader trend in the 'silver economy,' where products for older adults are evolving to prioritize active cognitive health. By moving toward puzzles that require complex deductive reasoning rather than just rote recall, users are engaging in more rigorous mental training, which aligns with global public health efforts to mitigate age-related cognitive decline.
