Both are free to download. The riddle box sells 3 one-off in-app purchases and 4=10 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
4=10 holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: 4=10 has 2.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 86% of The riddle box's written reviews are positive against 98% of 4=10's.
The riddle box ships an update monthly, 4=10 every 2 months. The most recent releases landed on October 13, 2026 and October 23, 2026 respectively.
