# 优酷视频HD vs K.O. Sudoku

The clearest difference is ads: 优酷视频HD at none against K.O. Sudoku's shown. 优酷视频HD also leads on ratings volume (31K vs 8) and rating (4.7 vs 4.4). K.O. Sudoku's advantage is review sentiment (85% vs 58%) and update cadence (every 4 days vs fortnightly). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. 优酷视频HD sells 22 in-app purchases, starting at $3.99 per month and K.O. Sudoku sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

优酷视频HD holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: 优酷视频HD has 31K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 58% of 优酷视频HD's written reviews are positive against 85% of K.O. Sudoku's, so the app with the better star average is not the one people write more warmly about.

优酷视频HD ships an update fortnightly, K.O. Sudoku every 4 days. Both last shipped on October 30, 2026.
