## What is NecroMerger?

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 array 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 tasks 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 your underlings to maximize your resource generation.

NecroMerger is a whole new type of game, which 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 massive benefits.

Expand your Lair

+ Attract Champions, merchants and thieves to your lair.

### 5/5 — Addicting!

*2026-08-21*

Very fun, addictive and high rewarding. It’s a shame the prices for brazilians aren’t adjusted and exorbitant though.
Great game!

### 5/5 — NecroMerger

*2026-08-18, version 1.79*

This game is so addicting and entertaining. Never thought a phone app would be fun but this truly is a gem and the other games by this dev are also fantastic. Love them all

### 5/5 — Finally, a quality game not fuelled by greed!!

*2026-08-13*

I’m seriously impressed by the level of thoughtfulness put into this game. It’s creative, witty, and a lot of fun. The dialogue and game mechanics are hilarious! The art is, dare I say, really cute?? Pixel art goodness!

Crazy how rare it is to find a breath of fresh air from all the AI junk out there. Ads are always optional and I actually want to watch them because 1) when a developer cares about making a good game and listens to their community, I want to support them and 2) the rewards are worth it.

It speaks true to being an idle game and is perfect to pick up casually.

[Spoilers ahead] I just unlocked the event lair and that has added a whole new layer (hehe… lair… layer) of gameplay and strategy.

Big thanks and huge kudos to Grumpy Rhino. I hope you make a billion dollars off this because you deserve it.

### 5/5 — Absolutely brilliant

*2026-08-10*

For a free mobile game, I struggle to think of any other games that compare in just how good this one is. Put simply, it’s a fun, humorous and enjoyable game.

If you want to, you can play without buying anything like ‘no ads’ and the double food and damage bonuses until you’ve decided you like the game enough to, that’s what did and it was well worth the price. 

It’s free, so give it a go :D

### 5/5 — Best Mobile Game

*2026-08-01, version 1.79*

I love this game so much, it’s so addicting. The art style is one of my favorites Ive seen in pixelated games and the monsters are designed well. I love the game, thank you for making this gem.

### 5/5 — Just a perfect game

*2026-07-31*

I very rarely take time to write reviews but this game is just kinda perfect. The art style is great, it’s simple to understand and the pacing is the best. The creators of this game should be very proud.

### 5/5 — So good

*2026-07-31, version 1.79*

I. Love. This. Game.

### 5/5 — Bestes Spiel, ohne Witz

*2026-07-30*

Macht so viel spaß und ist mega Spielerfreundlich ausgerichtet.

### 1/5 — 3 minutes in an ad

*2026-07-25*

Seriously, 3 minutes in an advertisement where I was directed to dowload screen 3 times. Close option apeared after suffering through 3 minutes of video followed by forced interactive content. Game publishers and developers own the decision of how bad/long they want ad experience to be so 1 star. I haven’t seen anything like this.

### 5/5 — I never leave reviews

*2026-07-19, version 1.79*

Honestly just a freaking great game
