How much does Pokemon shuffle cost?

I'm curious about the pricing structure of Pokemon Shuffle, as a casual mobile gamer. Could you elaborate on the cost involved in playing this game? Does it have a one-time purchase fee? Or are there recurring costs such as in-app purchases? I'm also interested in knowing if there are any free-to-play options available, or if the game relies heavily on microtransactions. Additionally, I'd like to understand if the cost is justified based on the game's content, replayability, and overall entertainment value. Could you provide a detailed breakdown of the pricing and perhaps compare it to similar mobile games in the market?
