This ancient Egyptian spiral race game, played between roughly 3100 B.C. and 2300 B.C., involved up to six participants guiding lion- and sphere-shaped pieces across a coiled snake-shaped track. Its rules weren't fully recorded and were only recently analyzed in depth in a 2024 study, making it a fascinating untapped app concept. Prior to this app, no iPhone implementation existed.

Verdict
The clearest difference is rating: Mehen at 5.0 against Eterna's 3.7. Eterna's advantage is ratings volume (15 vs 1) and iOS requirement (13.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Mehen holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: Eterna has 15 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 5, 2026 and October 4, 2026 respectively.
