Is there a good iOS app that mixes solitaire with word puzzles for brain training?

Solitaire Associations Journey is a distinctive hybrid puzzle app that successfully merges the logical structure of solitaire with the mental exercise of word association. For users seeking a brain-training game that isn't purely about matching symbols or finding words in a grid, this app provides a compelling alternative. Gameplay involves sorting cards into piles, but the sorting rule is based on discovering a common category or theme linking the words on the cards. This requires players to think laterally, expanding vocabulary and pattern recognition skills. A key feature praised by users is the unlimited lives system, which removes frustration and allows for extended, relaxed play sessions common during commutes or travel. The app also includes optional hints and a one-time purchase to remove advertisements, which reviews indicate is a popular choice due to the frequency of ad interruptions in the free version. While some word associations can be initially obscure, the trial-and-error process is part of the learning curve and satisfaction. The primary limitation, echoed in user feedback, is a desire for more levels and a level-replay feature for completionists, as the current content can be fully exhausted by dedicated players.
