Idol Party Diamonds

Flower Fest 2026 is generating serious hype — community guides are calling it the best Diamond event of the year. Most of that excitement is justified. But buried inside the lineup are bundles that will actively hurt your pity progress. This guide cuts through the FOMO and tells you exactly which Idol Party Diamonds bundles to skip during Flower Fest 2026, which one is genuinely worth buying, and what to do with the Diamonds you save.

F2P players can realistically earn **1,140 to 1,417 free Idol Party Diamonds** during Flower Festival 2026 by stacking seven confirmed sources: the Solo NPC path (1,088 baseline), 2-day login bonus (200+), daily and weekly missions (42–70), Achievement Gallery audits (150–200), club activities (15–30), gift codes (20–100 each), and April Fools Welfare overlap. That won't guarantee a featured SSR from scratch — hard pity sits at 4,480 Diamonds — but it's a serious head start if you're already sitting on saved currency.

The White Day 2026 event runs **March 6–22, 2026 (ending 23:59 UTC)**. F2P players can realistically earn **988–1,417 locked Diamonds** across all sources — enough to make real progress toward the limited SSR banner. Your single most important decision: solo NPC submission locks in 988 Diamonds guaranteed, while partnering with another player introduces coordination risk for a lower potential ceiling. Everything else builds on that foundation.

The White Day Event runs **March 6–22, 2026 (ends 23:59 UTC)**, and it's one of the more F2P-friendly events in Idol Party Diamonds — the highest-value locked tier doesn't require spending or a partner. Four locked Diamond tiers are on the table: 100, 500, 888, and 1,000. For F2P players, **988 locked Diamonds (Consolation + Participation)** is the realistic target, and it's fully achievable through a single NPC photo submission.

March 2026 is genuinely one of the best months to recharge — not hype, actual math. The White Day event (March 6–22) stacks on top of existing package bonuses, pushing the 3280+ tier to 74.4+ diamonds per USD. Add an unused First Recharge Bonus and that number nearly doubles. Here's every lever available right now, in the order you should pull them.

**Quick Summary:** The best-value packs in March 2026 are the **3280+656** (3,936 total Diamonds, USD 52.85) and **6480+1296** (7,776 total Diamonds, USD 96.00)—both carrying 20% bonus Diamonds and delivering 74.4+ Diamonds per USD. The White Day event (March 6–22, 2026) amplifies this value further. Top up with your 7–10 digit User ID; Diamonds arrive in as little as 7 seconds.
