Chalice: Revive once with 50% HP upon death Shard of Collapse: For the next 3 battles, all non-boss enemies start with 1 HP Shackles of Binding: +1 mana per turn, but shop prices increase by 25% Sanctuary Lantern: Fully restore HP whenever you enter a shop ■ Distinct Enemies — Every battle is a new puzzle.

Verdict

The call

The clearest difference is price: Sidius Nova at Free against Dungeon Merge!'s $2.99. Sidius Nova also leads on ratings volume (49 vs 2) and review sentiment (84% vs 74%). Dungeon Merge!'s advantage is rating (5.0 vs 4.4) and update cadence (every 3 days vs every 3 months). On ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Dungeon Merge! holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Sidius Nova has 49 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 84% of Sidius Nova's written reviews are positive against 74% of Dungeon Merge!'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sidius Nova ships an update every 3 months, Dungeon Merge! every 3 days. The most recent releases landed on October 23, 2026 and October 31, 2026 respectively.
