About this game

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 creatures (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 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 new, stronger (and even more tasty) creatures. Manage your lair and minions 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
+ 70+ creatures to spawn and merge.
+ Creatures have unique abilities to manage (resource generation, damage, deliciousness)
+ Legendary Creatures with big benefits.

Expand your Lair

Idle Merge Mashup

+ 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.

I don't make reviews very often anymore. That being said, this game deserves all its flowers. The character design is charming, offering lots of different monsters to work at collecting to merge more monsters! As resources collect over time to build more monsters, you can ignore the game for as long as you'd like and come back. There's also seasonal events to encourage the player to play every day for limited edition items and gems/coins. Plus the music is fun to vibe to. Easy to pick up & play!

gameplay is simple and fun, ads are for refilling resource gagues, which also refill offline so can be avoided. ads are also for unlocking golden chests that spawn 'premium' currency (gold and gems) which can unlock permanent upgrades. I approve of this style of ad injection so I paid for the ad removal (which is one and done, not a monthly sub!) so all in all super approve, super happy. Just unlocked the spellbook and still have dozens of creatures left to make.

Decent casual game. But I have gotten pretty bored with it about halfway through progression. The ads are way too much though. I know you don't "have to" watch them, but you kind of do or else you can only play 1/4 as much and will miss all of the timed events. The quick ads are pretty reasonable. The minute+ ads that make you wait to tap 3 different X's and still take over your phone to open the app store are overkill. *and now I'm getting the ads that won't close or give rewards. One star.
