Verdict
The clearest difference is ads: 9 Kings at none against UnderGuild's shown. 9 Kings also leads on monetization model (free vs free with in-app purchases) and rating (4.8 vs 4.5). UnderGuild's advantage is review sentiment (79% vs 62%) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. UnderGuild sells 19 one-off in-app purchases and 9 Kings sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
9 Kings holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: 9 Kings has 785 ratings behind it against 79, so its average is the more settled of the two. Written reviews complicate that: 79% of UnderGuild's written reviews are positive against 62% of 9 Kings's, so the app with the better star average is not the one people write more warmly about.
UnderGuild ships an update every 2 weeks, 9 Kings every 6 days. Both last shipped on October 25, 2026.
