幸運輪盤的選項可以自訂嗎？

可以。您可以自行輸入任意選項文字，並新增或刪除選項數量。輪盤會根據選項數量自動均分角度，每個選項的被選中機率相同（除非設定加權）。

Yes. You can input any option text and add or remove entries freely. The wheel automatically divides angles equally, giving each option an equal probability of being selected (unless weighted settings are applied).

結果真的是隨機公平的嗎？

是的。本工具使用加密安全亂數決定轉動角度，結合物理模擬的轉速衰減動畫，確保每次旋轉結果完全公平隨機，不受歷史結果影響，適合作為公正的決策輔助。

Yes. The tool uses a cryptographically secure random number to determine the spin angle, combined with a physically simulated deceleration animation. Each spin is completely fair and independent of previous results — suitable as an impartial decision aid.

可以設定某個選項更高的出現機率嗎？

可以透過重複新增相同選項來提高其出現機率。例如加入兩個「A」選項，則 A 的中獎機率即為其他選項的兩倍。這是最直覺的加權方式，無需複雜設定。

You can increase an option's probability by adding it multiple times. For example, entering "A" twice gives A double the chance of any single-entry option. This is the most intuitive weighting method, requiring no complex configuration.

幸運輪盤適合哪些場合使用？

適合用於：課堂隨機點名、決定今天吃什麼、多人遊戲決定順序、聚會抽獎活動、工作任務分配等各種需要公平隨機選擇的場合。旋轉動畫增加儀式感，讓決策過程更有趣。

Perfect for: classroom random selection, deciding what to eat, determining game turn order, party lucky draws, work task assignment, and any scenario requiring fair random selection. The spinning animation adds ceremony and makes the decision process more engaging.

如果不喜歡結果，可以重新轉嗎？

技術上可以。但輪盤工具的精神在於接受隨機結果，讓選擇不帶個人偏見。若預設「不喜歡就重轉」，則失去了工具的公正性意義。建議事前定好規則，例如「只轉一次」或「三次內有效」。

Technically yes, but the spirit of a randomizer is to accept the result impartially. Allowing "re-spin if I dislike it" undermines the tool's purpose. Set rules beforehand — such as "one spin only" or "best of three" — to preserve fairness.

選項很多時，輪盤還能清楚顯示嗎？

選項過多（超過 20 個）時，每個扇形面積縮小，文字可能不易閱讀。建議將相似選項合併，或在選項較少時使用以確保最佳可讀性。輪盤轉停後會清楚顯示結果名稱，不影響最終讀取。

With too many options (20+), each segment shrinks and text may be hard to read. Consider merging similar options or keeping entries under 20 for best readability. The result name is clearly displayed after the spin stops, so readability after spinning is not affected.
