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

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

Fun, Cute and Addicting! If you like merging things and love old school graphics and chip tune music, then this is made for you! Few ads, and each watched is rewarded. No major complaints, besides of course the everlasting desire to acquire more space. Lots of surprises to unlock, the game keeps you grinding through the day. Great F2P time buster.

I love this game; another great entry form Grumpy Rhino! Grindy, but the level it should be! In app purchases, but completely possible to get everything for free! Optional ads that can be avoided, but I personally reccomend them. Even an event system better than the last game! The only issue I can think of is that the devourer level right before unlocking the fridge has cravings that come from the fridge, which completely halts progress until you spam the Ogre fogotten minion enough. Please fix!

I wouldn't call this an idle game, it's more of a recharge based resource manager. It's about managing your limited space, which you need for resource generators, spawners and the components you are merging. The game continues to add new systems as you progress, preventing it from becoming stale, and those systems play well into the core mechanics evolving the complexity as you play. Progress feels rewarding and fun, and it's intriguing to see what you'll unlock next. All in all, a great game.
