The Seven Deadly Sins collaboration runs April 3 – May 3, 2026, and the free reward track is one of the best Blood Strike has offered. Confirmed F2P players can unlock 4 weapon skins, 3 Playpals, 3 avatars, 2 frames, and 1 exclusive title — zero diamonds — through login streaks, gallery tasks, friend invites, and Sin Mark Duel. Stack that with active April 2026 redeem codes worth an estimated 1,100–2,300 Gold equivalent, and budget players have a serious haul.
All Active Blood Strike Redeem Codes — April 2026
These codes are circulating across official Blood Strike social channels, community Discord servers, and verified creators. Community-validated as of early April 2026 — expiry varies, so redeem now.
MARCH21ST is confirmed expired — don't waste the attempt.
Where to Find New Codes First
Official Blood Strike Facebook page — milestone codes drop here first
Official Blood Strike YouTube — creator partnership codes in video descriptions
Blood Strike official Discord — event announcement channels
BlueStacks and Gamsgo — community aggregates, usually within 24 hours
One pattern worth knowing: new codes tend to drop around player milestone announcements. When you see a milestone post, check all channels immediately — those codes often expire within 48–72 hours.
How to Redeem Codes in Blood Strike
All redemption happens inside the game. No official web portal exists as of April 2026 — any third-party site claiming otherwise isn't official.

SDS Collab Rewards: Free vs. Premium
The event runs April 3 – May 3, but several sub-events have tighter internal deadlines. The ⚠️ markers below are the ones that'll hurt if you miss them.
Free Track (No Diamonds Required)
Premium Track (Spending Required)
Four of the best free rewards — Playpal Second Form Guardian, Avatar Meliodas, the title, and gallery frames — all expire April 29. Miss the April 13 gallery start and you're already behind.
How to Max Free Rewards Without Spending
Passive play won't cut it here. The SDS Collab has overlapping sub-events with hard cutoffs. Here's the sequence that works.
Phase 1: Login Streak (April 3 onward)
Start immediately. The Kar98k skin and Avatar Hawk are tied to cumulative logins across the full window. Missing early days creates a deficit you can't recover. Lowest-effort reward in the event — don't fumble it.
Phase 2: Friend Invites — Use the Overlap Window
The AK47 invite window closes April 19. The M700 window runs April 17–May 3. That April 17–19 overlap means invites during those three days count toward both reward tracks simultaneously. If your friend list is limited, concentrate all invite activity in that window. You'll double-dip on two weapon skins with the same actions. Community testing confirms this stacking is intentional — not a bug.
Phase 3: Gallery Tasks (April 13–29)
Sixteen days for Playpal Second Form Guardian, Avatar Meliodas, and the exclusive title. Don't wait until April 20 to start. Community experience shows players who delay past April 20 consistently fail to finish the chain before April 29. Start on April 13, full stop.
Phase 4: Sin Mark Duel Daily (April 3–May 3)
The QBZ95 skin requires active participation in Sin Mark Duel — not just logging in. This is the most common F2P mistake. Play it daily and prioritize reaching the Crest Stone Pillars first; they grant temporary Crest Abilities that make matches easier and count toward participation milestones.
Phase 5: Team-Up Tasks (April 20–May 3)
Playpal Hawk and Avatar Elizabeth need coordinated squad play. Line up teammates before April 20. Solo players can find event partners through Blood Strike's community Discord or official Facebook group.
F2P Resource Management
The SDS Collab free track is better value than the standard Battle Pass for F2P players this month. Four exclusive weapon skins, three Playpals, and a full cosmetic set — all free — outweighs what the pass offers at its price point during this window. If you're choosing where to focus limited time, the collab wins.
On the Lucky Draw: Avoid gacha for SDS skins until you've locked every free reward. The premium skins are attractive, but without a confirmed pity counter, community consensus is clear — F2P players who chase gacha during collab events consistently deplete resources before hitting pity, ending up with neither the skin nor enough currency for future events. The free track gives you four weapon skins. Lock those in first.
On the Battle Pass: Skip it this month if you're strict F2P. SDS free rewards are time-limited and irreplaceable; battle pass content rotates. Any budget you have goes further in the collab.
Minimum Spend Strategy
If you've secured all free rewards and want to reach into the premium tier, target Collab Stash Vouchers and Lucky Chests over raw Lucky Spin pulls. Vouchers give predictable value; spins don't.
LUCIAN Meliodas is the most spend-gated reward in this collab — top-up vouchers only, no free path. If that's your target, budget for it specifically. Everything else in the premium tier is technically accessible through Lucky Spin, but at variable cost.
For players doing a small top-up, getting the best rate matters. Buy Blood Strike gems cheap through a reliable top-up service to stretch your budget further on SDS Collab vouchers.
Common Mistakes to Avoid
Assuming passive login covers the QBZ95. It doesn't. Multiple players reported missing this skin despite daily logins because they never touched Sin Mark Duel. Active participation is required.
Missing the April 19 AK47 deadline. Tightest hard cutoff in the event. Don't start friend invites after April 6 and expect to finish in time. The AK47 Sacred Axe Rhitta is one of the best-looking free skins here — losing it to a missed deadline is avoidable.
Delaying gallery tasks. April 29 sounds distant until it isn't. Start April 13.
Chasing gacha before locking free rewards. Guaranteed rewards first, always. Gacha can wait.
Trying expired codes. MARCH21ST is dead. Verify against a current list before entering anything.
Frequently Asked Questions
Can I complete the SDS Collab entirely for free? Yes. All four weapon skins, three Playpals, three avatars, two frames, and the title require zero diamonds. LUCIAN Meliodas and the M4A1 Demon skin are spend-gated only.
How long are the April 2026 codes valid?BSTT2MPLAYERS and5MSTRIKERS run through May 2026.BSREWARD10K,BLOODSTRIKEFB, andTYSTRIKERS expire within April. Redeem immediately when you find a new code — milestone codes can expire within 48–72 hours.
What happens to event progress after May 3? Unclaimed rewards and incomplete tasks expire with the event. No grace period. Event currency tied to SDS tasks won't carry over. Finish everything before May 3.
Do these codes work on all server regions? Most are global, butBLOODSTRIKEFB has shown inconsistent behavior across regions. If a valid code fails despite correct entry and meeting level requirements, regional restriction is likely. Check the official Blood Strike Facebook page for region-specific announcements.
How often does Blood Strike release new codes? Roughly every 2–4 weeks around milestone events, major updates, or community celebrations. During active collabs, the cadence increases. Official Facebook and YouTube give the fastest notification.
Which free rewards should budget players prioritize? Kar98k Double Bow Harlit first (login — easiest). Then AK47 Sacred Axe Rhitta (friend invites, tight deadline). Then QBZ95 via Sin Mark Duel. Then gallery tasks for the title and Meliodas avatar. Weapon skins over Playpals for gameplay visibility, but Playpal Second Form Guardian is distinctive enough to chase if you're on track with everything else.
The SDS Collab is a genuinely strong event for budget players — the free tier alone justifies daily engagement through April. RedeemBSREWARD10K before it expires, lock in your login streak from day one, and treat April 17–19 as your most valuable three days in the entire event. Everything else follows from consistency.
If one premium SDS item is worth a small investment to you, getting the best rate on your top-up matters — compare Blood Strike recharge best price options before committing, especially when collab vouchers require specific diamond amounts to unlock efficiently.
