"## 2. Core gameplay mechanism (detailed version)

### 2.1 Basic reel rules
- Reel Configuration: Usually 3 reels × 3 rows (some versions are slightly different).
- PAYLINES: Mostly 25 (fixed), score points by matching the same symbols from left to right.
- Betting method: You can choose different face values (such as $0.01, $0.02, $0.05, $0.10, $0.25, $1), the total bet per spin = face value × number of paylines × bet amount per line.

### 2.2 Hold & Spin (locked spin) bonus gameplay
This is the most iconic core mechanic of Dragon Link.

#### Trigger conditions
- 6 or more Orb (Golden Ball) symbols appear anywhere to enter the Hold & Spin bonus round.

#### Reward rules
1. Initial number of spins: 3.
2. Lock and Reset:
- When a new coin symbol appears, pin it to the reels.
- Every time a new gold coin appears, the number of remaining spins will be reset back to 3 times**.
3. Gold Coin Value:
- A fixed amount is displayed on each gold coin symbol (calculated based on the current bet amount).
- The word Mini or Minor will appear on some gold coins, which directly represents the fixed small prize or winning amount.
4. Grand Prize Conditions:
- If all 15 grids on the screen are filled with gold coins, you will directly receive the Grand Jackpot (cumulative jackpot pool).
5. End of Round:
- Calculate the total value of all gold coins, plus the amount of Mini/Minor/Grand prizes that may be hit, and distribute them together.

### 2.3 Free Spins Mode
- Trigger condition: 3 Scatter (scatter symbols) appear anywhere.
- BONUS CONTENT:
- Get a fixed number of free spins (usually 6~10 times).
- Multiplier or Special Wild Expansion are often added to free games.
- In some versions, Hold & Spin can be triggered again in the free game, forming a "dual-layer reward".
