About this app

Developer Description

Merge monsters to feed the Devourer in this idle merge game mashup!

The Devourer is always hungry and it’s your job to feed it in this idle merge game mashup. Play as the NecroMerger and use dark magic to summon an army of monsters (skeletons, zombies, demons, banshees… the list goes on). Merge them from piddly little grunts into massive (and tasty) brutes, before feeding them to your ever hungry pet.

As you grow your Devourer you’ll attract the attention of merchants, champions and even rivals. Some can be useful, others must be fought… or fed to your insatiable pet. The bigger the Devourer grows the more your lair will expand and you’ll unlock powerful new abilities and spells.

Complete feats to unlock new stations and equipment… graves, altars, fridges and even a bathtub to hold excess slime. New stations will let you summon stronger (and even more tasty) minions. Manage your lair and monsters to maximize your resource generation.

NecroMerger is a whole new type of game that combines merge and idle mechanics with resource management to create something truly unique.

Grow Monsters
• 100+ minions to spawn and merge.
• Minions have unique abilities to manage (resource generation, damage, deliciousness).
• Create new Forgotten Minions by merging different types of minions together.
• Unlock powerful Legendary Minions with big benefits.

Expand your Lair
• Expand your lair. Unlock new equipment including; graves, altars and portals.
• Attract champions, merchants and thieves to your lair.
• Complete feats, master spells, brew potions.
• Use a unique prestige mechanic that takes you to unexpected places.

Events
• Take part in distinct repeatable events with special mechanics. You’ll battle your sister, keep bees and travel back in time.
• Head outside the lair to play seasonal events, whether that’s organising your own birthday party or playing Santa.
• Unlock unique skins and themes to change up your lair and its inhabitants.

Idle Merge Mashup
• A unique system of resource management.
• Resources generate even when you’re offline.
• Months of fun!

From the makers of Idle Apocalypse and Idle Mastermind, NecroMerger has the humour and inane chatter you’d expect of a Grumpy Rhino game.

Great unique game. Charming Sprites, Fun Soundtrack (although I wish there was more music). It has a great UI and a theme I really dig. The game has lots to explore and uncover. However, it's not without its flaws. Namely, there's a premium store if you'd like to spend money, there you can purchase upgrades such as add removal, bonus damage, increased storage etc. Although not needed, it would have been nice to include the add removal in the premium bundle instead of 2 separate purchases.

Just started playing the game and it feels like one those slow-burning but richer quality games, the art style is unique and the spawns are interactive in their own way. It almost feels like an ds game. Although, I wish they had more options to watch ads to refill(im not tryna spend my gems on refilling). ps(if the devs read this) please add more cheat codes im stuck in my tiny lair😔🙏🏽

cool game cool soundtrack and artworks. Also very addictive :) edit: had 5 stars but now 3. Reached the point where as a free2play player a wall is reached and almost no progress is possible.

its a fun game thats held back a lot by all the ads and microtransactions. it would be a lot better if you could just buy the full game (with no ads and unlimited mana, slime, etc.) for a single transaction like $5 to $10. the devs are obv way too greedy considering some of the microtransactions are like $10 for something that you can play through in 10 minutes.

Necromerger is a fun game, and I didn’t mind the ads or microtransactions at first they felt reasonable and optional. However, things changed when locked chests started appearing and blocking board spaces, requiring you to watch ads just to remove them. At that point, it stopped feeling optional and started feeling forced. It takes away from the core gameplay and turns what was a relaxing experience into an interruption-heavy one.
