The Best Idle Games for iPhone and Android

Mobile is where idle games make their money, which is exactly why you need a filter. These are the phone games worth the storage space, with the pay-to-win ones flagged so you know what you are walking into.

1

Antimatter Dimensions 9.4

web, steam, android, ios · free · hybrid · high complexity

The genre's reference implementation. Deep, free, no pay-to-win, and endlessly layered prestige. The one everyone else gets measured against.

Idle Obelisk Miner 9.2

android, ios, web · free · hybrid · high complexity

A genuinely deep mining incremental that does the unthinkable in mobile idle: zero ads, not even optional ones. Prestige artifacts, then whole new systems (stargazing, archaeology, fishing) keep unfolding for hundreds of hours.

Universal Paperclips 9.2

web, ios, android · free · active-heavy · medium complexity

The AI-alignment thought experiment as a four-hour masterpiece. You start clicking 'make paperclip' and end up dismantling the universe. No prestige, no grind — just a perfectly paced three-act arc that every incremental since has quietly copied.

Melvor Idle 9

web, steam, android, ios · freemium · pure-idle · medium complexity

Old-School RuneScape distilled into a spreadsheet you love. Enormous content, respectful monetization (base game is cheap, expansions are optional), and the rare idle game with genuine build variety.

Cookie Clicker 8.8

web, steam, android, ios · free · hybrid · medium complexity

The genre's ground zero. It invented the vocabulary everyone else borrows, and somehow the jokes still land a decade later. The Steam version with achievements is the definitive way to play.

A Dark Room 8.7

web, android, ios · free · hybrid · low complexity

The minimalist classic that proved a text incremental could be art. It starts with one button — 'stoke the fire' — and quietly becomes something you won't see coming. Topped App Store charts in 70 countries for a reason.

Egg, Inc. 8.5

ios, android · freemium · pay-to-win · pure-idle · low complexity

The ur-example of mobile idle done charmingly: hatch increasingly absurd eggs, ship them, prestige for Soul Eggs, repeat. Ten years of updates (Dark Mode landed June 2026) and 1.4M+ reviews — a genuine genre landmark.

Exponential Idle 8.5

android, ios · free · hybrid · high complexity

An idle game that's secretly a love letter to mathematics: progress by pushing equations, then unlock custom 'theories' with their own mechanics. Free, ad-free, and quietly one of the smartest games on mobile.

Idle Slayer 8.4

steam, android, ios · free · hybrid · medium complexity

A pixel-art auto-runner welded to a soul-collecting idle engine, with an Ascension tree deep enough to reward planning. Cross-platform cloud saves, 600+ achievements, and a solo dev who's still shipping major updates six years on.

Realm Grinder 8.4

web, steam, android, ios · free · pure-idle · brutal complexity

The faction-swapping grandaddy of strategic idlers: align with elves, demons, fairies and more, each rewriting how you play. Three stacked prestige layers and a decade of depth keep it a genre benchmark.

Theresmore 8.4

browser, android, ios · free · active-heavy · high complexity

The rare incremental that's genuinely a 4X in disguise — a tech tree, real armies, diplomacy and conquest layered onto number-go-up. A perennial r/incremental_games favorite, entirely free, no ads, and the new 1.2 idle queue system finally softens the click-heavy early game.

Leaf Blower Revolution 8.3

steam, android, ios · free · pure-idle · medium complexity

Exactly as silly as it sounds and far deeper than it has any right to be. What starts as blowing leaves becomes a sprawling automation game with fishing, gems, and a hundred systems. Free, no P2W, still updated.

Revolution Idle 8.3

steam, android, ios · free · pure-idle · low complexity

Full-released in May 2025, this is the friendly on-ramp to number-go-up: fill a circle, multiply, prestige, repeat, with new layers (Promotion, Infinity, Unity) unfolding as you go. Low friction, 670+ achievements, still actively expanding.

Legends of IdleOn 8.2

web, steam, android, ios · free · pure-idle · high complexity

The idle MMO that actually works: run a whole roster of characters across six worlds and 38 classes, each grinding a different system while you're away. Fully released Nov 2025 after years of steady growth.

Idle Planet Miner 8

ios, android · ad-supported · pay-to-win · pure-idle · high complexity

A surprisingly strategic space-mining idle where the real game is selling galaxies, not building them. Deep upgrade scaling, live tournaments, and a mothership economy that rewards genuine optimization — as long as you can look past the ads.

Cell to Singularity 7.8

web, steam, android, ios · freemium · pure-idle · low complexity

Evolution as an idle game, and a gorgeous one — tap your way from primordial cell through dinosaurs to AI and the stars. The late-2025 'Reality Reboot' redesigned prestige and it's more approachable than ever.

Idle Champions of the Forgotten Realms 7.6

web, steam, android, ios · freemium · pay-to-win · pure-idle · medium complexity

Official D&D wrapped around a formation-puzzle idler: slot hundreds of licensed champions into a line and optimize their buff chains. Deep and generous with free content — but the shop leans hard on paid champion packs.

Idle Skilling 7.5

steam, android, ios · free · pure-idle · medium complexity

The prolific LavaFlame2's earlier idler: 21 skills plus pet combat and spelunking sub-games, all ticking away at once. Free, sprawling, and a lighter on-ramp to the same dev's bigger IdleOn.
