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.

What I was looking for from an idle game

This game makes you feel like a necromancer while not forcing you to pay for anything.
The thematic, music, art, and overall play style is truly fun and addicting but the biggest pro is how the ads are not invasive. You can pay for permanent boosts and no ads but the game never puts you in a position where you feel like its the only way to make progress so the free to play aspect is rewarding still. I usually remove games like this since you experience ads like random encounters in an rpg but it doesn't get in the way of the experience.
Doing the daily's and managing it from time to time is a bit mandatory to make any real progress. You will encounter some missions that requires a bit of farming but unlocking the new monsters to summon and tools is very satisfying when you get there. It’s not meant to be beaten in a day so as long as thats kept in mind you can find yourself playing this and slowing upgrading your lair to become the necromancer you wish you could be.

Never change grumpy rhino

Another lovely innovative game from a developer I’ve loved for years. The game takes the base merge two mechanic and adds it’s own interesting twists with the champions and upgrades and smoothes out my biggest issue with most of these games by making generators purchase based with runes not chest drops. I bought the no ads pack and got exactly what I expected all ad bonuses given no issues. They even worked in a prestige mechanic that actually feels like a move forward not a reset step back. My only fear is that in a year or two the game won’t recive significant new content or events because I am so hooked on how much better this game feels to play than other merge two games I will not know what to do with myself if it leaves active development. Nevertheless this game deserves all the love and attention any other high quality cute quirky game recives!! (My only ‘complaint’ is that I NEED a cute skin for my lil tadpole, maybe something candy theamed???)

Incredible Game

This game is truly a perfect mobile game, at least for me. It has plenty of content to keep you busy whenever you have free time to play it, but rewards you as well for being afk, and doesn’t leave too much locked behind a time barrier or a paywall. Every currency in the game can be achieved by just playing, while obviously having pay options if you want to jump ahead. I just unlocked the event area and it absolutely blew away my expectations with the amount of content in this game. The art style is absolutely gorgeous, and the humor is on point.

All I ask is that developers, please keep pouring your love into this game. It’s obvious how much you enjoyed making this game, and I would hate to see it die and loose support like many mobile games do. As long as you make content I’ll be more than excited for every update!
