For an established BALL x PIT run, the strongest starting targets are Holy Laser, Maggot, Mosquito King, The Sun, and Black Hole. This ranking combines those picks with five other options from a published tier list, weighing practical payoff, how demanding each recipe is to assemble, and whether an evolution supports further combinations. It reflects evidence available as of October 8, 2026—not a universal order, and not a comparison of the Naturalist Update’s newer evolutions.
How evolution works in BALL x PIT
Evolution combines two different max-level balls into a new ball when a valid recipe is available. It is a run-time choice shown alongside Fusion and Fission when the required balls or passives are in your inventory; combining the pair also frees space for another passive or ball. See PCGamesN’s evolution guide for the mechanic and recipe context.
The order below is an editorial recommendation for ordinary runs, not an official ranking. PCGamesN’s November 3, 2025 tier list places five of these selections in S tier and the remaining candidates in A tier, but it does not establish a canonical order within either tier. The ranking here also considers recipe path and fusion potential, so a lower entry can still be the better choice for a particular build.
The 10 best evolutions to pursue
1. Holy Laser
Recipe: Horizontal Laser + Vertical Laser.
Holy Laser is the clearest all-around target in this list: it pairs two laser directions into an evolution PCGamesN calls one of the strongest. Pursue it when both laser components fit your run and you can bring them to max level; its position at the top reflects its broad appeal, not a promise that every run can assemble it in time.
#1 Best Overall
- Fuse Your Balls: The Ball Fusion system encourages explosive experimentation with over 60 randomized balls to equip and combine during your journey. Discover overpowered combinations and unexpected synergies from hundreds of possible outcomes.
- Build New Ballbylon: Expand New Ballbylon with over 70 unique buildings that provide gameplay bonuses and unlock further power-ups, new characters, and more! As your community grows, task homebound heroes with automated tasks to keep the resources coming while you dive deeper into the pit.
- Discover New Realms: Face legions of diverse enemies within the pit, battling through barren deserts, frozen caverns, savage forests and more. Each region offers its own unique set of hazards on top of hordes of increasingly challenging foes and mighty, screen-filling bosses.
- Recruit Fellow Hunters: As you explore the pit you’ll encounter fellow treasure hunters eager to add their skills to your expedition. Each character has unique, upgradable mechanics that totally change the way you play the game. Experimentation and adaptation are crucial to the success of New Ballbylon.
2. Maggot
Recipe: Cell + Brood Mother.
Maggot stands out for what it can do with other balls. Its spawned bonus balls can gain effects from another ball when fused, giving it support value beyond its own recipe. PCGamesN specifically notes its potential with Laser items and Nuclear, making it an attractive choice when your run can exploit those interactions.
3. Mosquito King
Recipe: Vampire + Brood Mother.
Mosquito King is one of the five S-tier picks in PCGamesN’s November 2025 list. It is a strong target if Vampire and Brood Mother already suit your run, but the recipe requires two specific components; do not chase it at the expense of a more attainable evolution that fits your build.
Rank #2
- "The physical edition contains 6 trading cards and a double-sided poster: on one side the basic, fusion and evolution balls of the game, on the other hand impressive artwork!
- Merge your balls: The ball fusion system invites you to explosive experiments with over 60 randomly selected balls to equip and combine on your journey. Discover overpowering combinations and unexpected synergies from hundreds of possible results
- Build New Ballbylon: Expand New Ballbylon with over 70 unique buildings that offer game bonuses and unlock more power-ups, new characters and more!
- Discover new realms: battle legions of different opponents in the pit and battle your way through barren deserts, frozen caves, wild forests and much more
- Recruit more hunters: as you explore the pit, you will encounter other treasure hunters just waiting to bring their skills to your expedition
4. The Sun
Recipe: Burn + Light.
The Sun is another S-tier selection and has an extra strategic draw: it can be used to make Black Hole. That makes it worthwhile both as an evolution in its own right and as a step toward a later combination, provided the Burn and Light path is practical in your run.
5. Black Hole
Recipe: The Sun + Dark.
Black Hole is in the published S tier, and PCGamesN describes the Sun-and-Black-Hole combination as powerful. It has a less direct route than a single pair recipe because The Sun must come first. Treat it as a payoff to plan toward, rather than assuming it is an early or easy pickup.

6. Nuclear Bomb
Recipe: Bomb + Poison.
Nuclear Bomb is an A-tier option in the November 2025 list and earns a place here for a straightforward, clearly identified pairing. It is especially relevant if your run already supports Bomb and Poison; Maggot’s noted compatibility with Nuclear also gives it a potential role in a broader build.
7. Spider Queen
Recipe: not stated in the cited PCGamesN material.
Spider Queen is among the A-tier candidates in PCGamesN’s list. The evidence supports its inclusion as a promising option, but does not provide enough recipe detail here to judge how accessible it is against the other entries. Check the in-game evolution prompt before committing upgrades to a specific route.

8. Laser Beam
Recipe: not stated in the cited PCGamesN material.
Laser Beam is another A-tier candidate. Its laser identity makes it a plausible consideration for a run already built around laser effects, but the available source material does not establish its exact recipe or a comparative performance advantage. Select it when the game offers the recipe and it fits your current plan.
9. Leech
Recipe: not stated in the cited PCGamesN material.
Leech appears in the A tier of the dated list, which makes it a reasonable alternative when its recipe becomes available. No recipe or specific synergy is established in the cited material, so its lower placement is a cautious editorial choice rather than a claim that it is weak.

Recipe: not stated in the cited PCGamesN material.
Mosquito Swarm rounds out the ranking as another A-tier candidate. It may be worth considering alongside Mosquito King when the run presents a suitable path, but the cited evidence does not establish a recipe or comparative case for preferring one over the other. Let the offered recipe and your build decide.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What changed with the Naturalist Update?
The available community page lists an “Ultimate Guide of Evolutions (Naturalist Update),” updated August 17, 2026 for game version 1.301. Its preview confirms that a Naturalist-era guide exists, but the full guide was not accessible in the material used for this ranking. A separate community recipe post lists added combinations such as Drill (Earthquake + Iron), Flesh Mound (Brood Mother + Flesh), and Mosquito Kingdom (Mosquito King + Mosquito Swarm). Those are recipe leads, not evidence that the additions outperform the ten ranked here. The new evolutions are therefore not ranked against the established picks.
Should you plan around Risen Ballbylon?
As of October 8, 2026, Risen Ballbylon is announced for November 12, 2026, with 20 new ball evolutions expected. PC Gamer reported the scheduled release on September 20, 2026. The expansion is upcoming, not available on the date of this ranking, so its evolutions cannot yet be evaluated here.
