15 Best Idle Games on Mobile, Ranked

Amidst the hustle and bustle of life, it can be hard to find the time to just sit back and relax. That’s where idle games come in. These are the perfect way to kill a few minutes (or hours) without having to put too much thought into it.

And while there are plenty of great idle games out there, we’ve narrowed it down to the very best for this list. So, whether you’re looking for something cute and casual or something a little more challenging, there’s sure to be an idle game here for you:

15. Tower of Hero

This is an idle game with a bit of a twist. In Tower of Hero, you need to help the heroes climb the tower by casting spells. The higher they get, the more difficult it becomes. There are over 100 heroes to collect, and you can upgrade them as you progress.

However, it places in the 15th spot since the rewards for playing are not as great as some of the other games on this list. You can only get so many heroes, and once you’ve upgraded them, there’s not much else to do.

14. Om Nom: Merge

The objective of this adorable puzzle game is to clear a path for Om Nom, the little green monster, by matching and combining pieces of candy. The game is simple yet challenging, and the cute graphics make it all the more enjoyable.

The problem with the game is that it’s not very original. It’s a lot like Bejeweled, and there have been many games like it before. However, the developers have done a good job of making the game their own, and it’s still a lot of fun to play.

13. Neko Atsume: Kitty Collector

Neko Atsume: Kitty Collector is a game where players provide food and toys for virtual cats in order to attract them to their yards. The cats will then leave behind items for the player, which can be used to purchase more attractive items to bring in even more cats. It’s a simple but charming game that’s perfect for when you need a break from reality.

However, the replayability factor is low and it can get repetitive after a while. As such, you may feel the urge to uninstall it after a month or two, that is unless you’ve grown attached to your digital feline friends.

12. Egg, Inc

If you’re looking for an idle game with a bit more depth than most, Egg, Inc. is the perfect choice. In it, you’ll be tasked with building up your own egg farm, hatching eggs, and selling them for a profit.

There’s a lot to manage in Egg, Inc., but that’s what makes it so addicting. You’ll constantly be trying to optimize your farm to get the most out of it. And as you progress, you’ll unlock new upgrades and buildings that will help you even further.

11. Realm Grinder

Realm Grinder is an idle game where players grow their kingdom by managing resources and building up an army to defeat monsters. There are a variety of ways to play the game, including different types of Buildings and Upgrades that players can purchase. The game also features a unique artifact system that allows players to further customize their gameplay experience.

The gameplay is quite slow, though, making it less than ideal for people who want a quick idle game fix. It’s also been criticized for being too complex and confusing for new players. However, if you’re willing to put in the time to learn the ropes, Realm Grinder is a deep and rewarding idle game that offers a lot of content and replayability.

Fallout Shelter is one of the best idle games on mobile, as it allows players to build up their own vault and manage it however they see fit. The game also has a lot of replay value, as there are many different ways to build one’s vault and there is always something new to do.

What’s great about Fallout Shelter is that it’s a game that can be played in short bursts or for long periods of time, making it perfect for when you have a few minutes to spare.
