Verdict

The call

Sipher Odyssey and Immortal Rising 2 both sit at 4.5 stars, but that hides the real split: 81% of Sipher Odyssey's written reviews are positive against 42% of Immortal Rising 2's. Sipher Odyssey also leads on ads (none vs shown). Immortal Rising 2's advantage is ratings volume (1K vs 22). On price, rating, update cadence and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Immortal Rising 2 holds the better App Store score, 4.6 against 4.5. That said, the two scores are not equally well evidenced: Immortal Rising 2 has 1K ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 81% of Sipher Odyssey's written reviews are positive against 42% of Immortal Rising 2's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 3, 2026.
