Blue Lock Rivals Codes: All Active Codes (September 2026)

Summer 2026 confirms Roblox's stranglehold on the multiplayer gaming scene. The platform has never had so many viral experiences running at once, and this July's ranking already blends established blockbusters with surprise newcomers. From Grow a Garden, which shattered every counter, to Steal a Brainrot, now a genuine cultural phenomenon, not to mention anime licenses (Blue Lock Rivals, Anime Vanguards) or more "cosy" games like Fisch, there's plenty to keep you busy over the holidays. Here's our selection of the best Roblox games right now, with the concept, how a session plays out, essential tips, and active codes to grab before they expire, for each one.

1. Grow a Garden — the garden that crushed everything

Grow a Garden is probably Roblox's biggest recent hit. Released in 2025, it crossed twenty billion visits in a matter of months, a pace never seen before on the platform, even for giants like Adopt Me or Brookhaven.

• Concept: you start with an empty plot, a few seeds, and a handful of Sheckles (the game's currency). You plant, water, wait, harvest, sell, reinvest.
• How to play: plant your seeds and let weather events (rain, snow, wind) mutate your crops. Mutated harvests sell for much more, which greatly speeds up progression.
• Strengths: relaxed gameplay, short sessions, rich seasonal content (Summer Part 2 in July).
• To unlock: rare seeds, pets, plot extensions.
• Active codes (July 2026): redeem via the gear icon, then "Redeem Codes". The list changes almost every week: keep an eye on the official Discord or specialized trackers so you don't miss any.

2. Steal a Brainrot — the cultural phenomenon of the year

There's no missing Steal a Brainrot this year. The game broke the all-time record for concurrent players on a single Roblox experience, peaking at over 25 million.

• Concept: you build a base populated with "Brainrots", those creatures straight out of viral TikTok memes. Each Brainrot generates money, and rarity drives up earnings.
• How to play: steal other players' Brainrots with bats, "slappers", and traps, all while defending your own. Join Admin Abuse events to grab exceptional creatures.
• Strengths: absurd meme-based humor, highly addictive social gameplay, fast progression.
• To unlock: legendary Brainrots (like La Vacca Saturno Saturnita), defense upgrades, skins.
• Active codes: as of mid-July 2026, no official code is available without purchasing an associated plush. Keep watching the official Discord: a first free code is highly anticipated.

3. 99 Nights in the Forest — the rising survival co-op

99 Nights in the Forest is this year's big horror-survival surprise, playable in co-op with up to four players.

• Concept: survive 99 consecutive nights in a cursed forest inhabited by cultists, mysterious entities, and above all a terrifying giant deer.
• How to play: form a team, camp near the fire, explore chests and watchtowers to find flashlights, food, and gear. Light is your ally: the deer fears flashlights and campfires.
• Strengths: oppressive atmosphere, tense co-op, progressive difficulty.
• To unlock: classes (each with its own perks), diamonds to reroll perks, equipment upgrades.
• Active codes (July 2026): forestwakesup26 grants free diamonds. Also remember the special chat code yay fishing (usable after reaching campfire level 2 and fishing with a rod), which gives 2 gems. Redeem via the Gems button in the bottom left, only from the lobby before starting a run.

4. Blue Lock Rivals — next-gen arcade football

An unofficial adaptation of the cult manga, Blue Lock Rivals is THE arcade football game of the moment on Roblox.

• Concept: 1v1 or team matches where each player controls a striker with a unique "Flow", essentially a signature technique.
• How to play: join the game's official Roblox group, reach at least level 10 to unlock code redemption, then chain matches and daily missions to earn Spins.
• Strengths: skill-based gameplay, faithful manga atmosphere, Flow tier list refreshed with every patch.
• To unlock: Flow abilities via Flow Spins, Style via Style Spins, Cash and boosts.
• Active codes (July 2026): NELSHIDOU, NEWCHEMSOON, and DEMON unlock Style Lucky Spins and Flow Lucky Spins. Watch out, some codes expire within 24 hours: redeem them right away. Tip: save your Lucky Spins for upcoming character additions instead of burning them all at once.

5. Blade Ball — the addictive sword duel

Blade Ball, released in 2023 by Wiggity, has become a nerve-wracking phenomenon: deflect a ball with your sword as it keeps accelerating until only one player remains standing.

• Concept: a ball bounces between players. Every impact makes it faster, and you need to deflect it with the right timing or take damage.
• How to play: pinpoint timing is essential. Too early, you miss. Too late, you get hit hard. Use Abilities (mobility, defense, offense) to turn the tide.
• Strengths: short rounds, constant adrenaline, very satisfying progression curve.
• To unlock: swords and skins, equippable Abilities, wheel spins.
• Active codes (July 2026): 14 codes still valid, including 4BVISITS (Bubble Wand skin), DUNGEONSRELEASE (50 Dungeon Runes), and GIVEMELUCK (x4 Luck boost in the AFK World). Codes are not case-sensitive: redeem via the "Extra" gift icon in the top left.

6. Anime Vanguards — the must-play manga tower defense

Anime Vanguards is THE manga tower defense game on Roblox in 2026, with an Extermination Part 1 event currently running in July.

• Concept: place units inspired by anime heroes on the map to fend off waves of enemies, upgrade, evolve, and chain runs.
• How to play: level up to unlock maps, summon units via the gacha system, upgrade their Traits and Memoria.
• Strengths: massive content, constantly shifting meta, very generous limited-time events.
• To unlock: rare units, Trait Rerolls, Memoria Shards, Iced Teas, Stat Chips.
• Active codes (July 2026): codes grant Trait Rerolls, Memoria Shards, Iced Teas, gems, and Stat Chips. Note that they are case-sensitive and generally expire two weeks after release. The list is updated weekly on the official Discord and on the wiki. Redeem via the Codes button on the right side of the screen, or through the profile.

7. Fisch — zen fishing, XXL edition

Fisch is Roblox's star fishing simulator, with over 400,000 fish variants to catch.

• Concept: cast your line, catch, sell, upgrade your gear and boat, then head off to ever more exotic zones.
• How to play: start with the basic quests to build up Cash, then invest in a better rod and better bait. On your first login, you get 200 Cash as a welcome bonus.
• Strengths: zen gameplay ideal for summer, full-fledged economy, numerous seasonal events.
• To unlock: rods, boats, skins, titles, event currencies like Sunshells.
• Active codes (July 2026): DrylandsIsFire, KingCrabstle, and Fischfest2026 respectively grant a Cactus skin, the Duck Floatie boat, and a Beach Umbrella, plus bonus Sunshells and consumables. Redeem via Menu > Other > "Type Code Here".

8. Mine a Planet — idle mining that runs 24/7

Mine a Planet is the idle hit of the moment, from Skydog Games.

• Concept: command a swarm of laser drones that continuously mine a giant planet, even while offline.
• How to play: upgrade your drones, unlock more powerful batteries and new mining zones. The loop is very satisfying, like a 3D space version of Cookie Clicker.
• Strengths: continuous progress even while AFK, space aesthetic, low barrier to entry.
• To unlock: special drones, Strong Batteries, Time Skips.
• Active codes (July 2026): four active codes as of mid-July, including BETABETA (1 Super Alien Treat). Rewards include Drone Packs, Strong Batteries, Super Alien Treats, and Time Skips. Redeem via the gear icon in the top right, then the input box at the bottom of the menu.

Going further

Beyond this top 8, a few classics remain must-plays this summer. Blox Fruits is still THE go-to RPG inspired by One Piece, with a monstrous end game for anyone who loves long-haul grinding. Adopt Me continues to dominate the "collect and trade" scene: it's where you'll find the wildest pet trades. Pet Simulator 99 and Brookhaven round out the landscape for fans of life simulation and collecting. On the challenge side, Tower of Hell and Murder Mystery 2 retain a loyal community. Finally, the "cosy" wave is here to stay: relaxing games (gardening, fishing, aquariums) are winning over an ever-wider audience. To stay up to date, pin Roblox's official top trending page and the Discords of the games you enjoy: most exclusive codes are announced there first, often with a lifespan of just a few days.
