<p><strong>假动作模式:</strong> 转盘减速后会有一次假动作，然后才会显示最终结果。</p>
<p><strong>摇摆不定模式:</strong> 在两个选项之间来回摇摆，增加悬念感。</p>
<p><strong>神秘模式:</strong> 先显示一个结果，然后突然改变！谁也猜不到最终会是谁。</p>
<p><strong>双重选择模式:</strong> 同时选出两名同学，适合小组活动。</p>
<p><strong>倒计时模式:</strong> 伴随紧张的倒计时动画，增加刺激感。</p>
<p><strong>心跳紧张模式:</strong> 伴随心跳动画，让结果更加扣人心弦。</p>
<p><strong>提示:</strong> 尝试不同的动画速度，获得最佳体验！</p>
