ONI Games · Published The idle and incremental games worth installing on Android in 2026, from deep classics to fast idle RPGs, with how each one makes money.
Idle games are the easiest way to play something good on a phone without giving it your whole evening. You set things in motion, put the phone away and come back to progress. These are the idle games on Android we think are worth installing in 2026, from deep incremental classics to fast idle RPGs.
Every entry lists how the game makes money, ads, in-app purchases or both, as shown on its Google Play page in September 2026. Disclosure: we make three of the games on this list, marked "our game". We placed them where we honestly think they fit, next to games we play ourselves.
Quick picks
- Best first idle game: Egg, Inc.
- Best for months of progress: Melvor Idle and Antimatter Dimensions
- Best idle RPGs: Idle Slayer, Legend of Slime and Idle Ronin: Cyber RPG
- Best idle tycoons: AdVenture Capitalist and Idle AI Factory: Robot Tycoon
- No ads at all: Melvor Idle and Unnamed Space Idle, the only two here that Google Play does not mark with "Contains ads"
1. Egg, Inc.
You start with one chicken and a coop and end up shipping eggs into space. Egg, Inc. by Auxbrain is one of the most polished idle games on the store and the one we recommend to people who have never played the genre. It has 4.7 stars and more than 10 million downloads on Google Play. Free, with ads and in-app purchases.
2. Melvor Idle
Melvor Idle, published by Jagex, is a RuneScape-style skilling game turned into an idle game: you train woodcutting, fishing, mining and combat skills that keep leveling while you do something else. It is slow in the best way and lasts for months. Free to start, with in-app purchases and no ads.
3. Antimatter Dimensions
A pure incremental game. Numbers grow, you reset for bigger numbers, and every reset opens a new layer you did not know was there. Antimatter Dimensions has 4.8 stars on Google Play and more than 1 million downloads, and it is the game to try if you like idle games for the math rather than the pictures. Free, with ads and in-app purchases.
4. Idle Slayer
An idle runner with pixel art: your hero runs, jumps and slashes through enemies on the way to bigger upgrades, and you can play actively or let it run. 4.6 stars and more than 5 million downloads. Free, with ads and in-app purchases.
5. Idle Ronin: Cyber RPG (our game)
You are the last Cyber Ronin in a neon city overrun by mechs. Your blade keeps swinging while you are offline, you recruit a squad of cyborgs, run dungeons for gold, diamonds and Unit Cores, and climb the 300 floors of the Neon Tower. It is fully translated into 14 languages and has cloud save through Google Play Games. Free, with ads and optional in-app purchases. More about Idle Ronin.
6. Legend of Slime: Idle RPG War
For once you play the monster. Your slime grows stronger and fights off the heroes who come for it. Legend of Slime has more than 10 million downloads and is one of the most popular idle RPGs on Android. Free, with ads and in-app purchases.
7. Idle Summoner: Pixel RPG (our game)
Tap the summoning gate to push your monster up a chain of 55, from Slime to Lord of the Abyss, and send your legion against the castles of the underworld across five biomes. When progress slows you rebirth for permanent bonuses. Free, with ads and optional in-app purchases. More about Idle Summoner.
8. Cookie Clicker
The game that started it for a lot of players. Click a cookie, buy grandmas, and watch it spiral into something much stranger than it looks. On Google Play the DashNet version is marked with ads and no in-app purchases. 4.4 stars and more than 5 million downloads.
9. Exponential Idle
An incremental game built on mathematics: you grow one number with ever bigger formulas and unlock new theories as you go. Calm, clever and very easy to put down and pick up. 4.7 stars and more than 1 million downloads. Free, with ads and in-app purchases.
10. Idle AI Factory: Robot Tycoon (our game)
Run a factory full of cheerful robots, automate every production line and grow from a small AI lab to a base on the Moon. The coins keep rolling in while you are away. Free, with ads and optional in-app purchases. More about Idle AI Factory.
11. AdVenture Capitalist
The classic business idle game by Hyper Hippo: start with a lemonade stand, hire managers so you never have to tap again and build a money empire. 4.5 stars and more than 10 million downloads. Free, with ads and in-app purchases.
12. Unnamed Space Idle
A space-themed idle game that Google Play lists without ads, a good pick if you want to play without interruptions. 4.1 stars. Free, with in-app purchases.
What makes a good idle game
We looked for games where progress continues while the phone is off, where upgrade choices matter, and where the game does not push you to pay to keep going. A good idle game should feel generous when you come back to it, not guilty when you leave.
What is the best idle game on Android?
If you only install one, start with Egg, Inc. It is polished, easy to learn and has more depth than it first shows. If you already know the genre, Melvor Idle and Antimatter Dimensions are the ones people keep playing for months.
Are there idle games without ads?
Yes. Of the games above, Melvor Idle and Unnamed Space Idle are listed on Google Play without ads. Most other idle games use ads, and many of them only show ads you choose to watch for a bonus.
What is an idle RPG?
An idle RPG is a role-playing game where your heroes fight and level up on their own, even while the game is closed. You make the decisions, what to upgrade, who to recruit, when to rebirth, and the game does the grinding. Idle Slayer, Legend of Slime, Idle Ronin and Idle Summoner are all idle RPGs.
