White Day 2026 runs March 6–22, 2026 (ending 23:59 UTC). F2P players who execute correctly can earn 988–1,417 locked Diamonds — enough for 6–9 pulls on the limited SSR banner. The single most important decision you'll make: solo NPC submission vs. partnering with another player. The math strongly favors solo. Here's everything you need.
Key Dates
Miss one window and you're leaving real Diamonds behind.
Available servers: Idol School, Shining Star, South East Asia Global (1001), Middle East (1002).
The code expiry on March 12 catches players every year. It expires ten days before the event closes — not on March 22. Redeem it Day 1.
All Reward Tiers
Participation stacks with everything. Win Consolation and you get 888 + 100 = 988 locked Diamonds. That's the F2P target.
The Submission Mechanic
Submit a couple-themed in-game PLOG or screenshot with your UID and description to either the official Discord (💖┊white-valentine) or the Steam page. No partner? Use an NPC — explicitly allowed, community-recommended.
Best Couple requires 5,376 Diamonds in gifting per event week. That's whale territory. Don't chase it unless you're already spending heavily.
Solo vs. Partner: The Math
Solo NPC Consolation: 988 locked Diamonds (888 + 100 Participation)
Lucky Award with a real partner: 600 locked Diamonds (500 + 100) — and you need competitive ranking to win it
Best Couple: 1,100 locked Diamonds — but requires 5,376 Diamond gifting floor
Solo NPC wins for almost every F2P player. You'd need to actually win Best Couple to beat it, and that costs far more than the 112 Diamond difference.
Step-by-Step Walkthrough
Day 1 Priorities (March 6)
Don't pull anything yet. First 30 minutes:
Redeem IT7BQGSC1V — Profile icon → Gift Code → enter code (case-sensitive) → Redeem. Expires March 12.
Check Achievement Gallery — community testing finds 50–200 unclaimed Diamonds sitting in social, affection, and login milestones. Collect everything.
Prepare your NPC couple photo — have it ready before the Couple Event window opens March 12.
Check your pity history — count current pull count and include locked Diamonds in your math.
Daily Checklist (March 6–22)
Daily missions — align with event tasks to double yield per session
Login bonus — Day 7, 14, 28 streaks pay most; missing one resets progress
Club rewards (30–60 Diamonds across the event)
Achievement Gallery for newly unlocked milestones
After March 12: confirm couple submission is registered
The alignment tip matters more than it sounds. If a daily mission requires gifting and an event task also involves gifting, do them simultaneously. Same Diamonds, half the time.
F2P Diamond Maximization
That's 7–9 pulls at 160 Diamonds each. Not enough to guarantee the SSR alone, but a real contribution toward pity — especially if you've been building reserves.
The Locked Diamond Misconception
Most players get this wrong. Locked Diamonds count fully toward limited banner pity. They can't be spent on non-gacha purchases like name changes, but every locked Diamond spent on the limited banner moves your pity counter forward exactly like a regular Diamond.
If you have 800 locked from previous events plus 988 from White Day, you're at 1,788 toward the 4,480 hard pity threshold. That changes your math significantly.
Late Joiners
Starting after March 13? The code is gone, but you can still hit 988 from NPC submission plus 50–150 from dailies, logins, and club rewards. The core F2P ceiling is still reachable.
Time-Limited vs. Ongoing Sources
Don't miss these:
Gift code IT7BQGSC1V — expires March 12
Couple submission — March 12–22
Daily login streaks — missing resets progress
Magic Box Exchange Cards — expire March 22
Available throughout:
Daily missions
Club rewards
Achievement Gallery (check weekly minimum)
The Hidden Sequencing Advantage
Most guides skip this entirely. The order you collect rewards matters for pity math.
Locked Diamonds count toward pity, so your effective pull budget changes depending on when you collect event rewards. Collect your 988 locked Diamonds before opening the banner on March 13, and those Diamonds are part of your starting budget. Pull first and collect later, and you're making decisions with incomplete information.
Don't open the limited banner until your Consolation submission is confirmed and the 988 locked Diamonds are in your account. The banner runs until March 22 — nine days. No urgency to pull Day 1.
Same logic applies to Achievement Gallery. Those 50–200 unclaimed Diamonds could be the difference between stopping at pull 19 (before soft pity) and reaching pull 20 (where your odds start improving).
Limited SSR Banner Guide (March 13–22)
Ten-day window. Pity resets March 22 with no carryover to standard banners.
The featured SSR is a support-type idol that scales with 2–3 skill upgrades — genuinely useful for gifting, affection mechanics, and stage performance. Not just a collection piece.
Should F2P Players Pull?
Pull only if you're within 1,500 Diamonds of the 4,480 hard pity threshold and you specifically need the support SSR. If you're at pull 5 with no prior pity, skip it — you won't reach the guarantee without spending, and you'll burn your White Day reserves for nothing.
The 70/30 rule: never commit more than 70% of total Diamond reserves to a single banner. If your entire reserve is 1,400 Diamonds, spending 1,000 here leaves you dangerously thin for future events.
The Soft Pity Trap
Soft pity begins around pull 20, meaning your SSR rate starts climbing. But stopping at pull 22–25 — after entering soft pity but before hard pity at 28 — is the worst possible outcome. You've spent most of the cost without the guarantee. If you're past pull 19, commit to pull 28. The incremental cost of pulls 20–28 is far smaller than restarting from zero.
For players calculating whether they can bridge the gap to hard pity, Idol Party Diamonds cheap top up March 2026 White Day is worth checking before you commit to a recharge.
Common Mistakes
Pulling Before Securing Event Rewards
Your 988 locked Diamonds from Consolation feed directly into your pity budget. Pull before collecting them and you're doing math on an incomplete number. Secure event rewards first.
Partnering for Lucky Award Instead of Solo NPC
Lucky Award pays 500 locked Diamonds. Solo NPC Consolation pays 888. The math: 888 > 500. Going solo is better even if you'd win Lucky Award — you need a real partner, competitive ranking, and you still net less. Only partner if you're genuinely competing for Best Couple.
Pulling Standard Banners During the Event
Standard and limited banners have separate pity pools. Every standard pull during March 13–22 does nothing for your limited banner pity. Direct drain, zero benefit to White Day goals.
Forgetting Achievement Gallery
Community testing consistently finds 50–200 unclaimed Diamonds sitting there. Check it at minimum once per week. Social milestones, affection thresholds, and login achievements all generate Diamond rewards that sit unclaimed until you manually collect them.
Letting Magic Box Exchange Cards Expire
They expire March 22 at 23:59 UTC. No grace period, no carryover, no exceptions. Use them before the deadline.
Diamond Spending Priority
Priority 1 — Bridge to hard pity if you're within range. Within 1,500 Diamonds of the 4,480 guarantee? Topping up to bridge that gap is the highest-value spend. You're paying for a guaranteed SSR, not gambling.
Priority 2 — Don't chase Best Couple unless already spending heavily. The 5,376 Diamond gifting floor is a significant commitment. The 1,000 locked Diamond reward doesn't justify the entry cost if you weren't already planning that investment.
Priority 3 — First Recharge Bonus. Haven't used it yet? Apply it to a 3,280+ Diamond pack. One-time per account, and the value multiplier is highest on larger packs.
For players comparing options before committing, Idol Party Diamonds recharge discount bundle best value 2026 frequently offers competitive rates with fast delivery — worth checking against in-game pack pricing.
Reward Tier List
S-Tier — Chase regardless of spending level:
Consolation Prize (988 locked total with Participation) — highest Diamond yield, fully F2P
Gift code IT7BQGSC1V — free Diamonds, zero effort, expires March 12
A-Tier — Worth pursuing with spare resources:
Limited SSR banner (if within 1,500 Diamonds of hard pity)
Achievement Gallery claims — passive income requiring only attention
B-Tier — Situational:
Lucky Award (500 locked) — only if you have a reliable partner and competitive standing
Magic Box Exchange Card rewards — value depends on exchange shop needs
C-Tier — Skip unless you're already spending heavily:
Best Couple Award — 5,376 Diamond gifting floor makes this a whale objective; 1,000 Diamond reward doesn't offset entry cost for most players
FAQ
How many free Diamonds can F2P players earn? 1,140–1,417 locked Diamonds with correct execution: NPC submission (988), code redemption, daily missions, login bonuses, club rewards, Achievement Gallery. Late joiners after March 13 can still reach ~1,038–1,138 without the code.
Do locked Diamonds count toward limited banner pity? Yes, fully. Every locked Diamond spent on the limited banner advances your pity counter identically to regular Diamonds. They just can't be spent on non-gacha purchases.
Solo NPC or partner? Solo NPC for almost every F2P player. Solo Consolation yields 988 locked; Lucky Award with a partner yields 600 — and you need competitive ranking to win it. Only partner if you're competing for Best Couple.
What happens to Magic Box Exchange Cards after March 22? They expire permanently at 23:59 UTC. No carryover, no grace period. Use them before the deadline.
Should F2P players pull on the limited banner? Only if you're within 1,500 Diamonds of the 4,480 hard pity threshold. Early pity with no prior buildup? Hold your Diamonds — you won't reach the guarantee without spending.
When does IT7BQGSC1V expire? March 12, 2026 at 23:59 UTC. Redeem via Profile icon → Gift Code → IT7BQGSC1V (case-sensitive) → Redeem. Day 1.
Does limited banner pity carry over after March 22? No. Pity resets when the banner closes and does not transfer to standard or future limited banners. Unspent pity progress is lost entirely.
White Day 2026 is genuinely one of the more generous F2P events — nearly 1,000 locked Diamonds from a single NPC photo submission is a strong baseline, and the daily stack on top gives you a real pull budget. The traps are real too: the early code expiry, the partner vs. solo math, the soft pity stopping point. But now you know where they are. Collect before you pull, sequence your rewards correctly, and you'll finish March 22 in a meaningfully stronger position than players who winged it.
