Blox Monsters Codes (June 2026) — All 10 Working Codes

All working Blox Monsters codes for June 2026

10 codes are currently active in Blox Monsters as of 24 June 2026, verified across ProGameGuides, Pocket Tactics, PCGamesN, RobloxDen, and Earnaldo. The newest code is Reluckyone, which delivers 5 Mutation Potions — the highest-volume mutation drop of any code in the list. All codes below were confirmed working in at least two independent sources checked on or after June 22, 2026. The exception is Ticket, which appears in Pocket Tactics and RobloxDen but not ProGameGuides or PCGamesN — it is included but treat it as slightly lower confidence than the rest.

Start with Reluckyone — five Mutation Potions is the best single-code return in the current list. Then redeem the Bloodline Rerolls (ShadowClaw gives 2, BonVoyage gives 1) before anything else if you are in early progression: your starting Bloodline matters more than a single Fruit or Crystal.

No expired codes were listed by any of the tracked sources as of June 24, 2026. Blox Monsters launched April 26, 2026, and kimi09 has not yet rotated out any of the codes added since launch.

What is Blox Monsters?

Blox Monsters is a Roblox monster-collecting RPG by kimi09, released on 26 April 2026. The game has logged approximately 3.98 million visits, 16,000–20,000 favourites, and ~9,540 concurrent players at a 93.7% positive rating (Roblox API, universe ID 10086454767, as of 24 June 2026).

The game’s core loop is structured around three actions: find wild monsters in adventure zones, weaken them in combat until their health is low, then capture them. Once captured, duplicate monsters can be fused together to rank them up to stronger forms. The Bloodline system adds depth to both capturing and egg hatching — rarer Bloodlines unlock better abilities, which is why the Bloodline Reroll items from codes matter early.

Core progression systems:

• Catch system — weaken wild monsters in PvE combat, capture at low HP; harder targets drop rarer species
• Bloodline system — your Bloodline determines the skill pool available during capturing and egg hatching; rarer Bloodlines give access to better abilities; Rerolls re-randomize this pool
• Fusion system — combine duplicate monsters to increase their rank and base stats
• Mega Evolution — spend Solitude Crystals to mega-evolve monsters into their strongest form (the Mega code covers one Crystal)
• Boss encounters — respawn approximately every 6 hours and drop rare eggs with a 15-hour hatch time; these are the primary source of the rarest monsters
• Incubator — passive progression system that generates resources over time
• Mutation system — Mutation Potions (from Reluckyone) unlock trait mutations; trait fruits (Miracle Birth Fruit, Gorgeous Fruit, Reverie Fruit) further modify traits and unlock abilities
• Season Spins — limited-time progression pulls tied to the current season rotation
• Capture Contest — competitive event where Capture Contest Tickets (Ticket code) let you enter and earn contest rewards

How to redeem Blox Monsters codes

The code redemption interface in Blox Monsters is accessible through the in-game Shop:

1. Launch Blox Monsters on Roblox.
2. Click the Shop button on the right side of the screen.
3. Scroll down to find the Codes text input box at the bottom of the Shop panel.
4. Paste a code exactly as written and click Redeem.

Codes may be case-sensitive — paste directly from this page rather than typing manually to avoid errors. If a code does not register, scroll to make sure you are in the Codes input box and not a search or filter field within the Shop.

Redeem all codes in a single session. The rewards drop immediately and go directly to your inventory.

What each reward type is actually for

Understanding how each reward type fits into Blox Monsters’ progression makes the codes significantly more useful than they look in the raw table.

Mutation Potions (Reluckyone — 5 of them): Applied to monsters to trigger trait mutations. Mutations are the game’s equivalent of stat-boosting upgrades that do not replace the base monster — they layer on top of existing traits. Using five Mutation Potions on a monster you plan to keep long-term is the highest-leverage use; do not apply them to disposable early-game catches.

Bloodline Rerolls (ShadowClaw — 2, BonVoyage — 1): Randomize your active Bloodline, changing the ability pool you draw from when capturing or hatching. If your current Bloodline is Common or Uncommon, using both Rerolls immediately is worthwhile — each re-roll is a chance to land a Rare or Epic Bloodline with dramatically better ability access. Save them if your Bloodline is already Rare or better.

Season Spins (SeasonReward — 3): Enter the current season’s spin pool, which contains limited-time cosmetics, monsters, and progression items tied to the season. Spin all three at once if you want to see what the current season table contains before spending additional resources.

Capture Contest Tickets (Ticket — 3): Entry into the Capture Contest competitive event. Hold these until a Capture Contest is active in-game — they have no value outside the event window.

Miracle Birth Fruit (10000CCU, NewTrait — 1 each): A trait fruit that influences trait inheritance during egg hatching or monster evolution. Two Miracle Birth Fruits from codes is a meaningful early boost for optimizing your first high-priority hatches.

Gorgeous Fruit (NewMutation — 1): Another trait fruit variant. Each Fruit type alters different parameters of trait expression, so using this alongside a Miracle Birth Fruit in sequence on the same hatching cycle can compound the benefit.

Reverie Fruits (SkillRefund — 3): Used to refund and respec skill allocations on a captured monster. Most useful after you have enough combat experience to know exactly how you want a specific monster’s skills distributed — do not spend them before you have a plan.

Solitude Crystal (Mega — 1): Required to trigger a monster’s Mega Evolution. One Crystal per code is the current rate, making each Solitude Crystal code worth holding until you have a fully ranked-up, well-Bloodlined monster ready for the Mega step.

The Bloodline system: why the early rerolls matter

Bloodline is the single highest-leverage variable in Blox Monsters’ early game. Your Bloodline determines which abilities you can access when you capture monsters or hatch eggs. A Common Bloodline will limit you to a small ability pool with low ceiling; an Epic or Legendary Bloodline opens abilities that are not accessible at all on lower tiers.

The two Bloodline Rerolls from ShadowClaw and the single Reroll from BonVoyage mean codes give you three reroll attempts total. If you land a Rare or better Bloodline in the first two, save the third for later. If you are still on Common after three rerolls, it is worth farming or purchasing additional Rerolls before investing heavily in capturing, since your Bloodline cap will limit the quality of every catch you make.

Where kimi09 drops new Blox Monsters codes

New codes for Blox Monsters are typically announced through the Blox Monsters Discord server (linked from the official Roblox game page) and via in-game notification prompts when you log in after an update. The codes in the current list correspond to CCU milestones (10000CCU), new mechanic introductions (NewTrait, NewMutation, Mega), and seasonal events (SeasonReward, Ticket) — suggesting kimi09 ties code drops to player milestones and content updates rather than to a fixed schedule.

No expired codes have been listed by any of the tracked sources as of 24 June 2026. That retention rate is unusually strong for a two-month-old Roblox game, but it is not guaranteed to continue indefinitely — check this page before your next session if any significant time has passed since you last redeemed.
