The Blood Strike Seven Deadly Sins crossover runs April 3 – May 3, 2026. F2P players who stay consistent can walk away with four weapon skins, three Playpals, three avatars, a crossover frame, and a title — no Gold required. Premium gacha skins exist for spenders, but the free ceiling here is genuinely strong. Here's how to claim everything.
What Is This Event?
A full crossover with the Seven Deadly Sins anime. It's not just a cosmetic drop — there's a dedicated collab mode, parallel reward tracks, and time-gated windows that require active daily engagement across the full month.
Structure: No Currency Shop
This is the most important thing to understand upfront. There is no Anniversary Gold, no sin milestone tier system, and no exchange shop. Official sources confirm this. Every reward comes through direct task completion, login accumulation, or friend invites — and each track is independent. You can't grind one activity to compensate for missing another. Miss a window, lose that item permanently.
Sin Mark Duel Mode
The collab mode features Crest Stone Pillars across the map that grant temporary Crest Abilities when activated. These are combat-relevant buffs, not cosmetic fluff — controlling pillars actually changes how engagements play out. It's worth playing on its own merits, and it's also the unlock path for the QBZ95 – Coffin of Eternal Darkness, arguably the most useful free skin in the event given the QBZ95's mid-range role.
Complete Free Reward Matrix
How Each Track Works
Login accumulation is passive — log in daily from April 3 and the Kar98k and avatar rewards build automatically. But you must manually claim them from the event hub. This is the most common mistake players make. Rewards don't auto-deliver.
Friend invites gate two weapon skins. AK47 Sacred Axe Rhitta requires invites during April 6–19. M700 Elizabeth uses a slash-price invite mechanic running April 17 – May 3. There's a three-day overlap (April 17–19) where both tracks are simultaneously active — coordinate with your squad during this window to progress both at once.
Gallery tasks run April 13–29. That's 16 days — the shortest critical window in the entire event. Playpal – Second Form Guardian lives here. Don't treat mid-April as a slow period; it's actually the most time-pressured stretch.
Team-up tasks for Playpal – Hawk run April 20 – May 3. These need coordinated squad play. Line up your regular teammates before April 20, not after.
Premium and Limited Rewards
These require Blood Strike Gold or gacha pulls. No evidence suggests they'll return after May 3.
Standard Blood Strike Gold is used for all pulls — no separate event currency. The Lucky Spin launched April 3 with LUCIAN Meliodas and Playpal Wild as featured items. The Featured Seven Deadly Sins Treasure banner houses the M4A1 Demon, Galil Elizabeth, and EMMA Elizabeth Goddess skins.
There's also a top-up event that grants Collab Stash Vouchers and Lucky Chests when you recharge Gold during the event window — bonus incentives for spenders, not a separate currency system. Players looking to stack Gold before the May 3 deadline can find competitive rates through Blood Strike top up discount 2026.
Gacha Transparency: What's Confirmed vs. Not
Confirmed: Featured Seven Deadly Sins Treasure uses standard Gold. Lucky Spin launched April 3 with Meliodas and Playpal Wild featured.
Not confirmed: Pity rates and guaranteed pull thresholds for this specific banner have not been officially disclosed. Community observations on Blood Strike's general spin mechanics exist, but applying those numbers here is speculation. If you're targeting a specific skin like the M4A1 Demon, set a Gold budget you're comfortable with and treat anything beyond it as a bonus — there's no reliable cost floor to plan around.
F2P vs. Spending: The Clean Comparison
Community testing confirms that a player who logs in daily from April 3, completes gallery tasks during April 13–29, sends friend invites during the correct windows, plays Sin Mark Duel for participation credit, and runs team-up tasks April 20 – May 3 can claim all 12 free rewards. That's a real offer.
The line is clean. Everything in the free matrix is earnable without spending. Everything premium requires Gold. No "almost free" mechanic to exploit.
Is spending worth it? For collectors, yes — especially LUCIAN Meliodas and EMMA Elizabeth, which are genuinely limited crossover cosmetics. For competitive players, the free QBZ95 and Kar98k are functionally sufficient. If you're a mid-spender evaluating where to focus, the M4A1 Demon is the most practically useful premium skin given the weapon's meta presence. Character skins are prestige items — worth it for collection, not for performance.
The Parallel Track Problem (Most Guides Miss This)
In events with a central currency shop, missing a day just means fewer coins — you grind harder later to compensate. This event doesn't work that way.
Each track (login, gallery, friend invites, team-up, mode participation) is independent and non-fungible. Missing gallery tasks doesn't get compensated by extra Sin Mark Duel matches. Missing invite windows doesn't get compensated by login streaks. "Just play casually and you'll be fine" is actively bad advice here.
The flip side: you don't need to grind for hours. You need to do the right tasks during the right windows. Twenty to thirty minutes of focused daily play covers most tracks if you're organized.
Mistakes That Actually Cost Players Free Rewards
Not logging in on April 3. The login track starts day one. Every missed day is a permanent gap — no catch-up mechanic exists.
Treating gallery tasks as a "later" problem. The April 13–29 window is 16 days. It sounds like enough time until it isn't. Start the moment they unlock.
Assuming rewards auto-claim. They don't. Build a daily habit of opening the event hub and claiming before you queue into a match.
Missing the invite overlap window. April 17–19 is the only stretch where both the AK47 and M700 invite tracks are simultaneously active. Coordinate friend invites specifically during these three days.
Waiting to form a squad for team-up tasks. Players who scramble for teammates in late April regularly run out of time. Lock in your regular squad before April 20.
Efficiency Tips That Actually Work
Play Sin Mark Duel daily rather than in bursts — participation credit accumulates per session
During April 13–29, gallery tasks come first if your daily playtime is limited
Only invite friends who are actively playing the event — inactive friends waste invite slots

FAQ
Can I complete the event after May 3? No. All task windows close on May 3. No post-event grace period is confirmed. Unclaimed rewards are gone.
Is there a pity system for the gacha banner? Pity rates haven't been officially disclosed for this specific banner. Don't rely on unconfirmed numbers — budget conservatively.
Do free skins expire after the event? Based on how Blood Strike handles event cosmetics, task-earned skins are added permanently to your inventory. Not explicitly confirmed in official patch notes for this event, so verify in-game after claiming if permanence matters to you.
Is Anniversary Gold real in this event? No. No Anniversary Gold currency, no sin milestone tiers, no exchange shop. Rewards come through direct task completion only. Guides describing an Anniversary Gold shop either reference a different event or are speculative.
What's the fastest way to complete everything? Log in daily from April 3. Start gallery tasks April 13. Hit the April 17–19 invite overlap hard. Have your team-up squad locked in before April 20. Sin Mark Duel is the least time-pressured track — spread it across the full month.
Are premium skins worth pulling? For collectors: yes, especially the character skins — they're genuinely limited. For competitive players: the free weapon skins are functionally sufficient. Purely a cosmetic decision.
The Blood Strike Seven Deadly Sins event is one of the stronger F2P crossover offerings in recent memory. Four weapon skins and three Playpals without spending is real — but only if you stay organized across the parallel tracks. Start April 3, don't skip gallery tasks, and coordinate your friend invites during the overlap window.
For players chasing premium skins, keeping your Gold reserves healthy before May 3 matters. Blood Strike cheap recharge gold options are available through BitTopup with fast delivery and competitive pricing — worth checking before you commit pulls on the Featured Seven Deadly Sins Treasure banner.
