Dominate the dungeon. Or let it dominate you. A turn-based deckbuilding roguelite — Dungeon Merge! Every run, a different strategy. A different hero. A different ending. ■ Unique Heroes — Not just different stats. A completely different way to play. Assassin: Double damage to a single target. Pick one. Make it count. Engineer: Stack shields, then unleash devastating area attacks. Defense is offense. Gambler: Free level-up rerolls. When luck becomes strategy. Noble: +1 level-up choice, gold-powered leveling at shrines. Money is your weapon. …Every hero demands a different strategy. ■ Diverse Skill Cards — Not collection. Combination. Your deck is your strategy. Chain Lightning: Hit up to 3 enemies in a chain Double Cast: Trigger the same skill twice in a row Replicate: Copy any card in your deck on the spot Skill grades: Common → Rare → Epic → Legendary Upgrade cards mid-combat and discover powerful combinations. ■ Powerful Relics — Sometimes a single relic changes everything. 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. Read the pattern or die. Treasure Goblin: Escapes after 7 turns if you fail to defeat it Snowman: Freezes you for 1 turn Crow: Forces you to discard a random card from your hand Face powerful bosses with unique attack patterns and multiple phases. ■ Seal System — The real challenge starts here.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Sidius Nova is free to download; Dungeon Merge! costs $2.99 up front. Sidius Nova sells 3 one-off in-app purchases and Dungeon Merge! sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
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.
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.
