The April 2026 Spring Festival is one of the most Diamond-dense seasonal events this game has seen — but only if you know where to look. F2P players can realistically bank 1,140–1,417 locked Diamonds across the event window. The limited SSR banner hits hard pity at exactly 4,480 Diamonds (28 pulls). Here's everything you need to plan pulls, prioritize spending, and not miss a single time-sensitive reward.
What You Need to Know Before It Starts
The Spring Festival mirrors the White Day 2026 event (March 6–22, 16-day window) in structure: a core participation phase, a shorter limited banner nested inside it, and a social submission mechanic that rewards solo players more reliably than competitive pair entries.
The single most misunderstood mechanic: locked Diamonds count fully toward limited banner pity. Officially confirmed. The solo NPC submission path alone yields 888 locked Diamonds — add the 100 locked Diamond participation reward and you're at 988 locked Diamonds with zero coordination required.
Time-Sensitive Checklist
Magic Box Exchange Cards expire at 23:59 UTC on the final day. Zero carryover. Use them early.
Who Should Prioritize This Event
F2P players: Solo NPC path is your highest-value action. 988 locked Diamonds, no ranking pressure.
Collectors: White Day 2026 set the precedent — six named exclusives (Warm White, Milk Tea Earl, Cloud Dream, Elegant One, Time Plot, Daily Neon) with no confirmed reruns. Spring Festival skins follow the same pattern.
Pull-focused players: If you're within 1,500 Diamonds of hard pity, this event's Diamond injection can close the gap.
Full Reward Breakdown
The distinction most guides skip: permanently limited vs. potentially returning rewards. Spending on something that reruns in six months is a completely different decision.
Seasonal Exclusive Costumes
Spring Festival will introduce a comparable slate to White Day's six named outfits. Seasonal limited costumes in Idol Party Diamonds have no confirmed reruns — community consensus treats them as permanently limited until the developer says otherwise.
Event Currency Items
Profile decorations, avatar frames, and accessories come through Magic Box Exchange Card exchanges, milestone tiers, and social participation. Cards expire at event close with no grace period. Exchange on Day 1 of receiving them, not the final day.
Community Tier List
That last row deserves emphasis. The Best Couple Award looks like the top Diamond reward. It isn't. The math is brutal: spend ~5,376 Diamonds in gifting to earn 1,000 locked Diamonds back. Solo NPC wins by a landslide.
Spring Festival Banner — Rates, Schedule & Mechanics
Schedule
White Day's limited SSR banner ran March 13–22 — a 9-day window that opened after the event's first week, giving players time to stack locked Diamonds before pulls went live. Expect the same delayed-launch structure here.
Featured Idol
The Spring limited SSR is a support-type idol that scales with 2–3 skill upgrades, with applications across gifting, affection, and stage mechanics. Support-types don't become obsolete when new DPS units release — that makes this banner more broadly pull-worthy than a pure stage-performance unit for most rosters.

Pity Mechanics
The 50/50 applies: lose it, and your next SSR on the limited banner is guaranteed to be the featured idol. Soft pity meaningfully increases SSR rates from pull 20 onward — if you're at pull 19+, stopping is almost always wrong.
Pity does not carry over between banners. Limited and standard banners have completely separate pools. Pulling on the standard banner during a limited event does nothing for your limited pity. If the banner closes while you're mid-pity, those pulls are gone. Plan accordingly.
Tracking Your Count
The game doesn't display a pity counter. Screenshot your pull history at banner launch, update after each session. Manual tracking is the only reliable method.

Every Free Diamond Source — Itemized
Realistic F2P total: 1,140–1,417 locked Diamonds.
New accounts skew toward the high end — the Achievement Gallery yields 600+ Diamonds in the first month from one-time unlocks. Returning players who haven't audited achievements recently should treat this as a Day 1 priority. Unlocks happen silently; no notifications.
Gift Code Redemption
Path: Main lobby → Profile icon (top-left) → Gift Code → ALL CAPS → Redeem → check mailbox.

95% of failures come from four causes: wrong case, wrong server, already redeemed, or expired code. Post-maintenance failures are common — wait 15–30 minutes before retrying. No active codes are confirmed as of April 1, 2026, but new codes typically drop at event launch. Check official Discord and Steam on Day 1.
Event Currency — Spend Priority
Magic Box Exchange Cards are the Spring Festival's primary currency. Hard expiry at event close. No conversion, no carryover.

Spend in this order:
Limited costumes and profile decorations — permanently limited, highest long-term value
Stamina items — extend farming capacity during the event window
Wish Coins — useful but not urgent
Filler items — only if you have surplus cards
Set a reminder 48 hours before event close to audit remaining cards.
Pull Strategy — Should You Pull?
Pull the Spring Festival banner if any of these apply:
You're at pull 19+ (inside soft pity — stopping wastes elevated rates)
You're within 1,500 Diamonds of hard pity
You lack a support-type SSR in your roster
Save if you're below pull 15 with fewer than 3,200 Diamonds total.
The 70/30 Reserve Rule
Never commit more than 70% of your Diamond reserves to a single banner. Hold 30% back. Exhausting everything on Spring Festival and having nothing left when a higher-priority May banner drops is a painful position to be in.
If you're approaching soft pity and need to close the gap before the banner expires, Idol Party Diamonds cheap top up April 2026 discount offers competitive rates. The highest-leverage top-up scenario is pull 18–22: a targeted 500–1,000 Diamond purchase converts a near-miss into a guaranteed SSR — far better value than pulling from pull 1 on a fresh banner.
For players in that position, buy Idol Party Diamonds online best recharge deal 2026 through BitTopup — fast delivery, widely used by the community.
When to Stop
Before pull 19, under 3,200 Diamonds total: Consider saving for May.
Pull 19+: Don't stop. You're in soft pity. Complete to hard pity or until you hit the SSR.
After winning the 50/50: Evaluate skill upgrades. Support-types benefit from 2–3 copies — if you're at skill level 0, a second copy has real value.
F2P vs. Spender Completion Guide
F2P players can complete the core event loop and earn the Consolation Prize without spending a single Diamond on pulls. The 988 + 100 participation reward alone puts you at 1,088 locked Diamonds before codes, achievements, or dailies.
Participation Requirements
Active servers: Idol School, Shining Star, SEA Global 1001, Middle East 1002. Server selection matters — gift codes are server-specific and one-time per account. Access requires the main lobby and a linked account.
Audit Achievement Gallery every 3–4 days, not weekly. Some categories unlock in clusters during active play, and waiting a full week means leaving Diamonds uncollected.
FAQ
How many free Diamonds can I earn during the Spring Festival? 1,140–1,417 locked Diamonds across the full event window. New accounts skew higher due to first-month Achievement Gallery bonuses.
Does pity carry over after the banner ends? No. Officially confirmed. Limited and standard banners have separate pools; neither transfers at banner close. Mid-pity pulls are lost if the banner expires.
Should I pull now or save for May? Pull if you're at pull 19+, within 1,500 Diamonds of hard pity, or lack a support-type SSR. Save if you're below pull 15 with under 3,200 Diamonds total.
Can F2P players complete the event without spending? Yes — core loop, participation rewards, and the 988 locked Diamond Consolation Prize are fully achievable free. The limited SSR needs ~3,200 pre-saved Diamonds minimum (soft pity, 50/50 win). Hard pity is a multi-month saving goal.
What should I spend event currency on first? Permanently limited costumes and decorations first. Stamina items second. Wish Coins and filler last. Never let Magic Box Exchange Cards expire unspent.
Are Spring Festival costumes ever rereleased? No confirmed reruns for any seasonal limited costume to date. Monitor official Discord and Steam for any announcements.
Fastest way to redeem a gift code? Main lobby → Profile icon → Gift Code → ALL CAPS → Redeem → mailbox. Post-maintenance failure? Wait 15–30 minutes and retry.
Dates, banner details, and reward structures will update when official Spring Festival April 2026 patch notes drop. Check back at event launch for confirmed figures.
