★★★★★ Game still lags randomly after trash iOS gloss update.
★★★★★ As you get to higher levels, the app is slow to the point of unusable until it crashes.

★★★★★ As you get to higher levels, the app is slow to the point of unusable until it crashes.

★★★★★ Have to watch ads for things but never get credit for them, watch multiple ads no reward.
★★★★★ - When a time limited event starts (4 a year), the event starts at the same time for everyone and ends at the same time for everyone.
Worse after an update12%

2 of the 1 and 2 star reviews.

★★★★★ Game still lags randomly after trash iOS gloss update.
★★★★★ The problem is not everyone gets the update before the scheduled start time and you don't get any compensation for that.
No customer support12%

2 of the 1 and 2 star reviews.

★★★★★ I recently switched from iPhone to Android, and reached out to customer service to restore progress/purchases on new phone and was told after a few days delay, 'sorry, we can't do that because they are different app…
★★★★★ I understand and support ads .
WHAT THEY ASK FOR
  • I like the game but wish there was a little more to do. 4★, Sep 6, 2026
  • Events are all on the same cooldown timer, I think each event should have its own cooldown timer so that you don't have to wait for 3 days to do an event. 4★, Jul 7, 2026
  • only criticism i have is that i wish the events cooldown was shorter or you could do multiple events at once(aside from the courtyard) i really don't like waiting a week since i have time on my hands and the game can… 5★, Dec 4, 2025
  • Please let me watch ads. 5★, Nov 27, 2025
  • My only recommendation is that I wish I could tap on the devourer so that he reacts as if I'm petting him? 5★, Nov 5, 2025
  • I wish i was able to play it on here and transfer my data. 5★, Sep 12, 2025
  • This happens every playthrough and the Dietician is useless because that's also gate kept by level (makes her pretty pointless in early game/rebuilding after a Time Machine use, when you need all the help you can get). 3★, Sep 2, 2025
  • Having to build up and merge two level 5 sources is great but I wish that I would get back at least a level three if not higher. 4★, Jun 24, 2025

Worth the money16%

14 of the 4 and 5 star reviews.

★★★★★ I bought the ad free version and it is worth it - when they say ad free they mean ZERO ads.
★★★★★ The grind feels worth it every time.
★★★★★ Of the hours of entertainment I've gotten, I found purchasing the golden upgrades or whatever they're called, super worth it from the beginning.

7 of the 4 and 5 star reviews.

★★★★★ just a simple and fun game.
★★★★★ It is entirely worth it, and a quick and easy game to pick up and play whenever during the day.

Useful, it helps6%

5 of the 4 and 5 star reviews.

★★★★★ It helps pass time and sometimes you hit a bit of a wall and it usually just takes a minute to remember what you need to focus on to propel forward.
★★★★★ I've been playing free all this time and didn't mind the ads because they're all opt-in and have good rewards, but I recently decided I've had this game long enough to drop the money for ad-free and it's a game changer!
★★★★★ all ads give genuinely useful items.

Low stress fun fr

The pixie art is wonderful, shout out to the artist(s)! The game runs smoothly, and events bring familiar yet fresh themes with generous time limits and rewarding progress. It’s a charming, relaxing game you can enjoy at your own pace. Engaging, but never too demanding of your time. Huge appreciation to the developers for such a thoughtfully crafted game!

★★★★★Oct 20, 2026
Love it

I love this game. I’ve had it for almost 2 years at this point and that is saying something since I usually keep games for like a month max. There is consistent updates keeping you hooked with new content and I have bought a few in game purchases to show my support for the developers which is also unusual. I recommend it for anyone who wants a chill merging game with that undead Halloween feel.

★★★★★Oct 17, 2026
Best Phone game I’ve played.

I’ve been playing this for years. Never gets old. I literally play it every day. Easy to play. Seems simple but is surprisingly complex.

★★★★★Oct 4, 2026
Nerf Cubes?

Now it’s impossible to get enough cubes; the game has become unreasonably затяжной in terms of meta‑leveling. I regret updating the client; the reward for the protector was significantly reduced.

★★★★★Sep 27, 2026
Good Game!

One of the few games with accurate mobile adds that delivers exactly what it promises and I can say I’m very satisfied with this game thus far.

★★★★★Sep 25, 2026
Favorite merge game

Genuinely one of if not THE best merge game i have ever played. Wonderfully balanced, delightful art, great music. I bought the ad free version and it is worth it - when they say ad free they mean ZERO ads. You just get the ad rewards for free.

Store description

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 + Expand your lair. Unlock new equipment including; graves, supply cupboards, lecterns. + Attract Champions, merchants and thieves to your lair. + Complete tasks, master spells, brew potions. 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 all the humour and inane chatter you’d expect of a Grumpy Rhino Game.
