Spin a Fem All Fems: 137 Units and 17 Rarities Explained

Spin a Fem is a Roblox idle tycoon built around collecting 137 free Fems across 17 rarity tiers, and knowing which units earn the most per plot slot is the difference between slow grinding and a fully stacked income engine. This guide maps every Spin a Fem all fems entry, breaks down income scaling by rarity, and lays out practical unlock paths so you can plan your rolls instead of gambling blindly. Whether you are after the rarest Fems or just want the strongest per-slot earners, the data below comes straight from the official Spin a Fem page on Roblox and community-tracked Spin a Femboy Wiki data.

How Rarity Tiers Scale Per-Slot Income

Every Fem you roll lands in one of 17 rarity brackets, and each bracket's per-slot income roughly doubles at every step up the ladder. Community-tracked values place a Common at the baseline and put the top-tier Mythic Flex units orders of magnitude above the bottom tiers, which is why chasing rare Fems early feels slow but compounds fast once slots fill. The list below summarizes the bracket structure, with approximate per-slot income bands reported by players (exact values vary by mutation, pet buffs, and active events).

The takeaway: the Spin a Fem best income fems you can place are almost always the ones in the upper half of this table, but unlocking them takes dice upgrades and a lot of patience. A solid mid-game plan is to fill your open plot slots with Epic and Legendary units first, then gradually swap them out as you roll into Mythic and above.

How the 17 Rarities Break Down

The 17 rarities are not a straight ladder. The first nine tiers form the standard income progression, while the remaining eight are event-locked or limited windows that rotate around the calendar. According to community data, event Fems often carry a 1.5x–2x income multiplier over their non-event counterparts of the same base tier, which makes them some of the strongest Fems to farm during active windows.

Why Flex Fems Sit at the Top

The Flex tier is treated as a sub-category of Mythic, but the community wiki notes that Flex Fems earn meaningfully more than regular Mythic units of the same slot. They are only obtainable through Marble dice and occasional special rolls, which is why they are listed among the rarest Fems in the game. Holding even one Flex unit can shift your passive income curve noticeably, especially when paired with mutation rerolls that land on the income stat.

Spin a Fem Fem List: Categories and How to Find Them

The full Spin a Fem fem list groups units by both theme and unlock method, and understanding the categories helps you decide where to spend your dice. Themed sets usually appear together in the dice pool, while hidden and secret Fems only drop from specific dice types or during event windows. Below is a practical overview of how the 137 units cluster, drawn from community-tracked sources.

The exact split fluctuates as the developer adds seasonal content, so the numbers above should be read as a working baseline rather than a fixed roster. For a per-unit breakdown, the Spin a Femboy Wiki Fems page is the most complete community reference, though it lags behind live patches by a few days.

Standard Themed Fems

The standard themed pool makes up the bulk of the 137 Fems. These include recurring visual themes (nature, urban, fantasy, sci-fi, holiday) and are the units you will roll most often from Silver through Diamond dice. Because they are accessible at relatively low dice tiers, they form the backbone of any starter plot and give new players a steady stream of income to fund upgrades.

Limited, Hidden, and Secret Fems

Limited event Fems are the rarest Fems in the standard pool because they only appear during active event windows. Hidden Fems are slightly different — they exist in the data but only drop under specific conditions (such as a certain dice tier combined with a luck boost). Secret Fems are the smallest pool and tend to require either Marble-tier rolls or redeemed codes, which makes them genuinely Spin a Fem rare fems rather than just higher-numbered entries.

Spin a Fem Best Fems for Income per Slot

Picking the Spin a Fem best fems is less about which unit looks strongest on paper and more about which slot you are filling. A single Mythic Fem in your best plot tile will outperform a stack of Common units, but the income delta shrinks once you start stacking mutations and pet buffs. The table below walks through practical slot priorities based on community testing and player reports.

Players who focus on stacking their highest-earning slots with Flex and Mythic Fems first tend to see faster income growth than players who fill every available slot evenly. If you are still building your dice pool, working through the dice tier list can help you prioritize which dice to upgrade first so your next spin has a realistic chance at higher rarities.

Best Income Fems by Tier

Across every available Fem, the Spin a Fem best income fems are reliably the ones that combine a high base rarity with a positive mutation roll on the income stat. According to community data, the difference between an unmutated Mythic and a fully-mutated Mythic can be several multiples in per-slot income, which is why mutation rerolls are worth saving up for.

Pet Synergy for Best Fems

Pets are the second-largest income modifier after mutations, and pairing the right pet with a high-rarity Fem can push its per-slot earnings well above the baseline. The pet tier list ranks the most impactful companions, and the income-boost pets at the top of that list are the ones most players stack alongside their Flex and Mythic Fems. A common mid-game setup is one income-pet per plot tile holding a Mythic-or-better Fem.

Spin a Fem Rarest Fems and How to Unlock Them

The rarest Fems are spread across three unlock paths: Marble dice, event windows, and codes. Each path has its own grind, and the rarest Fems in the game are usually locked behind a combination of all three. Community data puts the Flex tier as the single hardest group to complete, with several Flex units only obtainable during specific event reruns or through developer-issued codes.

Marble Dice and Flex Fems

Marble sits at the top of the standard dice ladder and is the main source for Flex-tier Fems. Rolls are expensive, which is why most players treat Marble pulls as a long-term goal rather than an everyday expense. The community reports that even with Marble dice, landing a Flex Fem can take hundreds of rolls, so stacking luck boosts from pets and potions before a Marble session is standard practice among endgame players.

Event-Locked Fems

The eight event rarity tiers rotate on a calendar, and each window usually lasts a few weeks. Event-locked Fems often come back during reruns, but the exact timing is set by the developer. According to community data, players who log in consistently during events tend to collect most of the event pool within two or three rerun cycles, while players who skip windows may wait months for a specific Fem to return.

Code Drops and Event-Exclusive Fems

Codes are a smaller but reliable source of rare Fems. Active codes are usually posted on the developer's social channels, and redeeming them through the in-game code menu grants either a specific Fem or a dice that can roll one. The community maintains a working list of active codes on the wiki, and several Youtubers track new codes as they drop — for a walkthrough of how to roll and unlock more rare Fems efficiently, the how to get fems guide covers the practical side of grinding and luck stacking.

A Phased Plan for Building Your Full Collection

A practical collection plan saves you from burning dice on low-impact rolls. Start by locking in your income core, then expand outward into cosmetic and Flex units. The table below breaks a typical progression into phases, with the Fems and dice to focus on at each step.

This phased approach matches the income scaling in the first section and lines up with the dice upgrade curve. Players who follow a similar order report a steadier climb than those who chase Flex units immediately, because they lack the pet and mutation support to make those slots pay off early.

Common Mistakes When Collecting Fems

The most common mistake is filling outer-ring slots with Mythic and Flex Fems before the inner slots are optimized. Because outer-ring multipliers are lower, even the strongest Fems earn less there than a mid-tier Fem in a top slot. Another frequent error is spending dice during events without checking which event Fems are still missing from the collection, since event pools rotate and missed windows mean waiting for the next rerun.

Long-Term Collection Goals

Once your plot is full and your dice pool covers Marble, the remaining grind is mostly event-locked and Flex Fems. A reasonable endgame target is to clear every event tier within its rerun window and to land at least one Flex Fem in your top slot. Players who maintain that level of collection tend to have the strongest passive income in the game, because their stack combines the highest base tier with mutation and pet multipliers.

Comparing the Strongest Fems in Spin a Fem

Ranking the Spin a Fem strongest fems is partly subjective because mutation rolls and pet buffs change the math, but the table below summarizes how each top tier stacks up in practice. Income values are community-reported and assume a baseline plot with average pet support.

The same Fems also appear in the wider Spin a Fem fem list, but the income values above only count the highest performers in each tier. Lower-rarity units in any given bracket will earn noticeably less, which is why the practical gap between a top Mythic and a mid Mythic can be larger than the gap between mid Mythic and a high Legendary.

Frequently Asked Questions

How many Fems are there in Spin a Fem total?

There are 137 free Fems spread across 17 rarities, according to the official game page and the community wiki. The roster grows during event reruns, so the count can inch up over time.

What is the rarest Fem in Spin a Fem?

The rarest Fems are the Flex-tier Mythic units, which drop almost exclusively from Marble dice. Some Flex Fems only appear during special roll conditions, which is why they are considered the hardest entries to complete in any Spin a Fem fem list.

Which Fems earn the most per slot?

The Spin a Fem best income fems per slot are Flex-tier units with positive income mutations, especially when paired with a top-tier income pet. Among standard tiers, Mythic and Celestial Fems are the next-best anchors for high-multiplier plot tiles.

How do I unlock event Fems?

Event Fems are unlocked by rolling event-themed dice during the active event window. Aquamarine, Glacial, Pride, Angel, New Year, Sakura, Pirate, and Cyber dice each gate a specific event pool, and missing a window usually means waiting for the next rerun.

Do I need all 137 Fems to max income?

No. Income is driven mainly by the highest-rarity units in your top slots, so a smaller collection of Mythic and Flex Fems can outperform a larger roster of lower-tier units. Completing the full 137 is mostly a cosmetic and completionist goal rather than an income requirement.
