### Gameplay Mode Description
* **Classic Double Deduction**: Authentic Wenzhou gameplay with strict card combinations, demanding precise card order and excellent teamwork.
* **Hundred Changes Double Deduction**: The Joker and Ace can be used as "wild cards," replacing any ordinary card except the wild cards. This greatly increases the probability of forming multiple bombs and complex card combinations, making the game faster-paced and more exciting.
* **Thousand Changes Double Deduction**: Building upon the foundation of Hundred Changes Double Deduction, **the number and power of bombs are further increased**, supporting the creation of "giant bombs" with an extremely large number of cards through the combination of various cards. The situation changes rapidly, and a comeback can happen in an instant.
