Verdict
The clearest difference is rating: Memory King at 4.4 against KoolPuzz's 3.0. Memory King also leads on ads (none vs shown) and ratings volume (332 vs 1). KoolPuzz's advantage is update cadence (every 9 days vs every 3 months) and review sentiment (100% vs 91%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Memory King sells 3 one-off in-app purchases and KoolPuzz sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Memory King holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Memory King has 332 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of Memory King's written reviews are positive against 100% of KoolPuzz's, so the app with the better star average is not the one people write more warmly about.
Memory King ships an update every 3 months, KoolPuzz every 9 days. Both last shipped on November 1, 2026.
