Beginner Guide

From first launch to your first elite reroll — start here.

Last updated:

Build A Blue Lock Squad launched on Roblox in late June 2026 and quickly became one of The LockerRoom’s flagship gacha squad builders. If you are opening the game for the first time, this beginner guide walks you through everything that matters in your first hour — tutorial completion, free reroll sources, code redemption, and the reroll mechanics that define progression.

The game is a Blue Lock-themed squad builder where you roll 200+ anime characters, slot eleven into a lineup, and raise squad OVR through rerolls and refreshes. You do not need Robux to progress competitively if you follow the free-resource path outlined below.

Before You Start

Three facts every new player should know:

Group membership is mandatory for codes. Join The LockerRoom Roblox group before attempting any promo code. Codes fail silently or show errors without membership.

Finish the tutorial first. The Settings menu — where codes are redeemed — only becomes available after you complete the short in-game tutorial. Launch the game, follow the onboarding prompts, and enter the lobby before hunting codes.

Reroll replaces your weakest player. Every reroll swaps out the lowest-OVR squad member for a new random pull. This is not a full squad reset. Read Reroll Strategy before spending tokens.

First-Hour Checklist

Complete these steps in order during your first session:

  1. Join The LockerRoom group on Roblox (free, required for codes)
  2. Launch Build A Blue Lock Squad and finish the tutorial
  3. Like the game on its Roblox page — grants reroll rewards
  4. Favorite the game on its Roblox page — additional reroll rewards
  5. Redeem all three active codes — ELUSIVE, OneThousandCCU, OneThousandMembers from Working Codes for 25 rerolls and 15 refreshes total
  6. Talk to Sendou NPC in the lobby — verify like, favorite, and group status for up to 10 bonus rerolls (see Free Rerolls)
  7. Claim login rewards if prompted — see Login Rewards for daily coin and bonus details
  8. Read Reroll Strategy before spending any tokens
  9. Check the Tier List so you know which characters to keep

This sequence takes 15-20 minutes and delivers more starting rerolls than most players earn in their first week of random play.

Understanding Core Mechanics

Roll / Reroll — The gacha system pulls random Blue Lock characters. Reroll specifically replaces your lowest-OVR lineup member with a new pull.

Refresh — Resets the character options in your current roll without replacing a squad member. Use when your pool shows multiple strong candidates.

Squad OVR — Average overall rating across your eleven-player lineup. Higher OVR improves match outcomes and leaderboard rank.

Rarity tiers — Common, Rare, Epic, Legendary, and Elusive (added in the ELUSIVES Update). Higher rarity means higher stat ceilings.

Cash / Coins — In-game currency from login rewards, quests, and expired codes like SpiriXSolos (which once granted 20k cash). Used for additional rolls and squad costs.

Where to Redeem Codes

Open Settings via the icon in the bottom-left corner of the screen while in the lobby. Paste codes exactly as written — they are case-sensitive. Full walkthrough with video on How to Redeem Codes.

Sendou NPC Explained

Sendou is the lobby NPC who rewards players for supporting the game. After liking, favoriting, and joining the group, walk up to Sendou and interact to verify your actions and claim up to 10 free rerolls. This is separate from code rewards and stacks on top of them.

Make Sendou part of every login alongside Daily Quests and Login Rewards.

Characters to Chase Early

Consult the Tier List for full rankings. As of July 2026, prioritize:

  • NEL Isagi, NEL Rin, NEL Nagi — Elusive-tier S-rank from the ELUSIVES update
  • Kaiser, Bachira, Barou, Shidou, Sae — Legendary and Epic staples
  • Lavinho, Kunigami — Strong A-tier options for early squads

See Best Characters and Elusive Characters for detailed breakdowns.

Common Beginner Mistakes

Spending all rerolls immediately — Early rerolls are valuable, but blind spending wastes tokens. Target your weakest OVR slot after checking the tier list.

Skipping group join — Every code fails without group membership. Join first, always.

Using expired codes — DUELS, SpiriXSolos, RELEASE, and others no longer work. Stick to Working Codes and check Expired Codes for archives.

Ignoring daily systems — Login rewards, daily quests, and Sendou provide renewable rerolls that outperform one-time code bursts over time.

Running scripts on your main account — Auto-farm and infinite reroll scripts risk permanent bans. See Scripts Overview for safer alternatives.

Your First Week Roadmap

Day 1: Complete the first-hour checklist above. Reach 60+ OVR with smart rerolls.

Days 2-7: Login daily, talk to Sendou, complete daily quests, check for new codes on Updates Hub. Follow High OVR Squad Guide for OVR benchmarks.

Week 2+: Chase Elusive-tier characters, optimize refresh timing, join Discord & Community for code announcements.

Game Stats (July 2026)

Build A Blue Lock Squad reached a peak of roughly 1,400 concurrent players on July 21, 2026, with steady growth since its June 29, 2026 launch. Milestone codes OneThousandCCU and OneThousandMembers reflect that momentum.
