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.

I love this game, the most played game on my phone. I usually don't go for this particular genre, but this game is actually quite...cute. I love all the random phrases and the silly banter. 7☆ but it would have been 10☆ if the events lasted a little longer, the recharge time a little shorter, and the cost of themes a little cheaper, but overall, one of the best games I've ever played.

I actually love this game, I think it's very fun. I like the vibes, art style, gameplay. I like everything about this game, except it's clear to me that the developers have put a lot of time and effort into researching various psychological hooks to get people to spend money, and the amount of effort that they've put towards that could have been put towards improving content and player experience. Instead, the vast majority of the game is simply inaccessible without an enormous time/$ investment

Strangely addicting. Not difficult to play, but it's about managing resources, space, time, and focus. Compellingly made. Art is great. The prices for things in the shop with in-game currency (gems, coins) seem high, but since you can gain that currency without spending a real cent, it's not a huge problem. You can buy gems and coins for convenience or specific boosts, but it is unnecessary. If you enjoy the game, buying the no-ads thing is well worth it.
