# JJ麻将 vs 推理学院

The clearest difference is rating: JJ麻将 at 4.7 against 推理学院's 3.7. JJ麻将 also leads on ads (none vs shown) and ratings volume (197 vs 15). 推理学院's advantage is iOS requirement (11.0 vs 13.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. JJ麻将 sells 38 in-app purchases, starting at $3.99 per month and 推理学院 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

JJ麻将 holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: JJ麻将 has 197 ratings behind it against 15, so its average is the more settled of the two.
