### 1/5 — 準確度太低了

*2026-03-22, version 3.0.3*

競賽題目答案填完後有問題，卻沒有被糾正反而過關贏得比賽

### 5/5 — 可以做的更完善一點

*2025-12-19, version 3.0.3*

希望可以做數字優先輸入模式，長按我想填的數字進行鎖定再按格子填入數字或筆記，這樣就不需要按格子再按數字了

### 4/5 — 還不錯

*2024-07-01, version 2.0.0*

找了好久終於找到一款可以聯機遊玩的數獨了。建議創建PK房間的設定介面可以更新一下配色，黑底黑字什麼也看不清⋯很影響觀感，也沒有找到可以調整配色的地方。希望軟件可以越做越好～
