Criminal Case is free to download and play, allowing players to dive into exciting detective adventures without any initial charges. However, the game does include optional in-app purchases that can enhance your gameplay experience. These purchases typically consist of extra energy points, which allow you to continue playing without waiting, as well as items that can assist you in solving cases faster.

In addition to in-app purchases, Criminal Case contains advertisements that appear periodically during gameplay. These ads generally appear between levels or cases, providing non-intrusive breaks during your detective work. While the core gameplay remains free, these optional purchases and advertisements help support the developer and offer players additional ways to enjoy and progress in the game more conveniently.
