The April 2026 Flower Festival runs for 16 days with a nested 10-day SSR banner, six reward mechanics, and a new Flower Castle party room. F2P players can realistically collect 1,140–1,417 locked Diamonds across all free sources. The standout: a support-type SSR that simultaneously buffs both the Affection and Live Performance systems, plus the Solo NPC path — your single highest-yield free source at 988 locked Diamonds alone.
Quick Overview
Six mechanics run simultaneously, which sounds like a lot. It isn't, once you know the priority order. No prerequisite event completion required — everything's accessible from the main event hub after the April patch.
What's actually new: The support SSR is the first in recent memory to dual-buff both major systems at once. The Flower Castle party room is genuinely new. The handheld accessory from Flower Lottery didn't exist in White Day 2026. The cosmetic lineup is stronger. Everything else — login streak, mission board, puzzle, lottery structure — mirrors White Day's skeleton.
All Six Event Mechanics
Flower Prayer Cards — Primary daily token source. Do this first, every day.
Romantic Puzzle — Yields Diamonds + tokens on completion.
Flower Lottery — Chance-based; includes the new handheld accessory exclusive to this event.
Solo NPC Path — 988 locked Diamonds + 100 participation bonus. No coordination needed, no spending required. Highest F2P priority.
Personal Spending Ranking — Pearl Dream mount and Pearl Ashes ring for top spenders. Not F2P accessible.
Exchange Shop — Redeem flower tokens for limited cosmetics including the Brown Shirt outfit.
New Cosmetics
Three outfits are permanently limited with zero rerun history: Brown Shirt, Warm White costume, Milk Tea Earl seasonal wear. The Ray Dance avatar frame comes from the login streak. Pearl Dream mount and Pearl Ashes ring are spending-track only.
Free Diamond Sources: Every Number
F2P total range: 1,140–1,417 locked Diamonds. Here's exactly where each comes from.
New players get an additional 600+ Diamonds from first-month milestones on top of this.
Login Streak
Log in for 2 consecutive days to claim 200 Diamonds + the Ray Dance avatar frame. Miss a day and the streak resets — you lose milestone rewards at days 7, 14, and 28. Set a daily alarm. Missing day 7 doesn't just cost that day's reward; it wipes your milestone progress entirely.
Solo NPC Path
988 locked Diamonds + 100 participation bonus = 1,088 Diamonds total. No spending, no coordination. Complete it daily throughout the event. This is your top priority, full stop.
Daily Mission Board
Roughly 3–5 Diamonds per day, totaling 42–70 Diamonds over 16 days. Small individually. Clear it every session before doing anything else — it compounds.
Achievement Gallery — The One Most Players Miss
Audit this every 3–4 days. It yields 50–200 Diamonds per cycle on a rolling refresh. Over 16 days, that's 150–200 Diamonds most players leave unclaimed because they check it once at event start and forget it exists. Don't be that player.
Flower Tokens: Earn Fast, Spend Immediately
Flower tokens are the event's exclusive currency. They expire at event end with no carryover. This is the most important mechanic to understand before the event starts.
Farming Order
Complete Flower Prayer Cards daily — primary income
Finish the Romantic Puzzle — bonus tokens alongside Diamonds
Use Flower Lottery entries as they become available
Exchange Shop Priority
Spend tokens on limited cosmetics the moment you have enough. Don't hoard.
Brown Shirt outfit (permanently limited — highest priority)
Warm White costume (permanently limited)
Milk Tea Earl seasonal wear (permanently limited)
Other limited cosmetics

What to Skip
The Best Couple Award costs approximately 5,376 Diamonds and returns 1,000 Diamonds — a net loss of over 4,300 Diamonds. Avoid it at every spending level.
Limited Banner: Honest Pull Math
Rates and Pity
Pull cost: 160 Diamonds
Hard pity: 28 pulls = 4,480 Diamonds (guarantees SSR)
Soft pity: Begins ~pull 20 (~3,200 Diamonds)
Featured rate: 50/50 on pity SSR
Worst case for featured SSR: Two full pity cycles = 8,960 Diamonds
Pity doesn't carry between limited and standard banners. Track your pull count manually with screenshots — there's no in-game counter.
Should You Pull?
F2P players: Skip the banner if you have fewer than 3,200 Diamonds saved. Your event Diamonds are locked currency, and the math doesn't work unless you're already deep into pity.
Spenders: The support SSR's dual-buff is genuinely useful if you have a support gap in your roster. Pull if you're within 1,500 Diamonds of hard pity or past pull 19 without a support SSR.
If you're chasing the featured SSR and need to top up, Idol Party Diamonds top up discount 2026 offers competitive rates — the best value bundle runs approximately 3,280+656 Diamonds for around $53, roughly 74.4 Diamonds per USD with first-recharge doubling applied.
Flower Festival vs. White Day 2026
The structural similarity is real. But the support SSR's dual-buff role, Flower Castle, the new handheld accessory, and a stronger cosmetic lineup make this a meaningfully better event — not a reskin.
Daily Checklist
Run this every single day, in this order:
Log in — protect your streak
Clear Mission Board — 3–5 Diamonds daily
Complete Flower Prayer Cards — primary token income
Solve Romantic Puzzle — Diamonds + tokens
Use Flower Lottery entries — as available
Spend tokens on priority cosmetics immediately — never hoard
Beginner Strategy
Lock in the login streak and Solo NPC path first. Those two sources alone yield over 1,200 Diamonds with zero complexity. Skip the banner — your first-month milestones add 600+ Diamonds on top of event rewards, making this an exceptional onboarding window.
Veteran Strategy
Your edge is in the details. Audit the Achievement Gallery every 3–4 days — most veterans skip this and lose 150–200 free Diamonds. Track banner pity manually from day one. Spend tokens on cosmetics the moment you have enough; don't discover on day 14 that you've been sitting on Brown Shirt tokens since day 5.
Known Issues
If rewards aren't claiming post-maintenance, wait 15–30 minutes for server sync. No major unresolved issues reported at launch.

FAQ
How many free Diamonds can I earn? 1,140–1,417 locked Diamonds across all event sources. New players add 600+ from first-month milestones. The Solo NPC path contributes 1,088 of that total on its own.
Is the banner worth pulling on? Only if you're within 1,500 Diamonds of hard pity or past pull 19 with a support SSR gap. F2P players under 3,200 Diamonds saved should skip it entirely and focus on cosmetics.
Can I get rewards after the event ends? No. Flower tokens expire with no carryover. Brown Shirt, Warm White, and Milk Tea Earl have no rerun history — when the event closes, they're gone permanently.
Fastest way to farm flower tokens? Flower Prayer Cards daily, supplemented by Romantic Puzzle completions and Flower Lottery entries. Spend tokens on limited outfits immediately.
Do I need to complete previous events first? No. All Flower Festival content is accessible from the main event hub after the April patch.
What happens if I miss a login day? Streak resets. You lose milestone rewards at days 7, 14, and 28. The 2-day streak for 200 Diamonds + Ray Dance frame is easy — the longer milestones require an unbroken chain. Treat daily login as your single highest-priority action.
The Achievement Gallery audit cycle is the mechanic virtually every guide skips. Check it every 3–4 days across the full 16-day event and you'll extract 150–200 Diamonds most players simply leave unclaimed. On tight F2P margins, that's potentially one more pull.

Enter your UID from Profile > Account Info for fast delivery. First-recharge doubling makes early top-ups significantly more efficient than waiting.
The Flower Festival is one of the stronger seasonal events in recent Idol Party Diamonds history. F2P reward density is real, the cosmetics are permanently limited, and the support SSR has genuine utility. Run the daily checklist, spend tokens immediately, skip the Best Couple Award, and you'll come out ahead — regardless of your spending level.
