Merge creatures and feed them to a hungry devourer to unlock new abilities and stations.

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.

★★★★★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.

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…

★★★★★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.
