Games like Fortune Mill

The Squirrel's verdictPerfect Tower II layers tower defense, automation, and both vertical and horizontal progression into a free idle game with a median playtime around 116 hours. Reviewers describe the systems as genuinely engaging but needlessly opaque—many say a wiki tab is required to understand builds and advancement. Weekly updates have been consistent since launch. Suits players who want actual build decisions rather than clicking whatever upgrade is available.

Not for you if you find wiki-dependent progression frustrating or want transparent systems you can understand in-game.

The Squirrel's verdictIdle Research structures its progression through distinct tiers—Flasks, then Cylinders—where clearing one layer opens a substantially different game beneath it. It is free, though reviewers flag premium-currency microtransactions tied to gameplay speed rather than cosmetics only. One widely cited review notes the game has no autosave, which caused total progress loss during a power outage. Median playtime reaches 62 hours.

Not for you if you want autosave as a baseline feature, or object to premium-currency transactions that affect progression speed.

The Squirrel's verdictRow Divers is a single dive-and-upgrade loop: runs complete themselves, you buy upgrades, numbers scale until 100% completion. At $2.99 and around 2.4 median hours, it fits players who want a short, low-commitment incremental without multiple disconnected game modes. Reviewers note the game cannot run while minimized, and that mechanical variety stays thin from start to finish.

Not for you if you want multiple distinct game modes to switch between, or need the game to progress while running in the background.

The Squirrel's verdictMilitary Incremental Complex adds weapon assembly, contracts, a stock market, and prestige runs to the upgrade loop, giving more interlocking systems than most games in this category. Reviewers praise the early game but flag that manual weapon assembly grows tedious as complexity increases, slider-based prestige management frustrates, and the stock market eventually overshadows other mechanics. Median playtime sits at 22.2 hours at $9.99.

Not for you if you dislike repeated manual assembly sequences or slider-heavy prestige resets that reviewers describe as slow and grindy.

The Squirrel's verdictIdle Colony keeps the idle-incremental skeleton of Fortune Mill: upgrade trees, meta-progression, numbers that build on each other. The difference is focus. Instead of five loosely connected minigames, you run one colony system, drawing paths and managing resources, and reviewers note it needs active attention rather than idle waiting. Median playtime sits at 17.2 hours.

Not for you if you want to leave the game running and return to progress later, since reviewers report it barely advances while idle or closed.

The Squirrel's verdictFortune Mill's core loop is buying upgrades that change ratios across linked systems; Supply Chain Idle builds a whole game around that idea instead of five separate minigames. You set up production chains, upgrades shift ratios, and you relink everything for efficiency. No gacha, no scratch tickets, no minigame stitching. It is free.

Not for you if you want distinct minigames rather than one continuous optimization puzzle about ratios and logistics.

The Squirrel's verdictBoth are casino-themed idle games built from multiple minigame rooms with cross-upgrades and light clicking between waits. Gamblers Table trades Fortune Mill's five distinct minigames for a single tech tree across tiers (Copper through Diamond), with a random Visitor mechanic replacing gacha pulls. Median playtime sits at 17.3 hours, shorter for those chasing full completion.

Not for you if you want deep per-minigame upgrade trees rather than one repeated tier-based progression path with limited real decisions.
