## Core Gameplay and Rules

- Click any square to select; click an adjacent (up/down/left/right) square to trigger a swap

- If a straight line (horizontal/vertical) of ≥3 identical animals is formed, it is considered a match and cleared

- After clearing, the top square falls to complete the match, and a new block is generated at the top to complete the match; chain elimination is supported

- If no match is formed after a swap, an animation will revert to the original position

- Automatically shuffle the deck when no moves are possible, and automatically remove initial connections after shuffling.
