Event Badge Shop — Spend Now
Synchro ranking closed Aug 15. Badges still exchange until the in-game shop countdown ends — Hololium and event memories first.
The Synchro Summer Sparkle score ladder closed on August 15, 2026 at 19:59 JST. Ranking attempts no longer count, but Event Badges sitting in your inventory are not souvenirs — they expire. Hello! Brand New Summer! badges stopped exchanging on August 11, 19:59 JST, six days after that rally ended. Treat Synchro badges the same way: open the event shop today, read the countdown, and empty the rare stock before QualiArts locks the counter.
This page is the spend list for August 16 onward. Pair it with the after-Synchro gap guide and the archive Synchro Summer Sparkle write-up. The miComet gacha is a separate clock — it still runs through August 17, 10:59 JST.
Why the shop outlives the ranking
Score Challenge ranking and the badge counter are two systems. The event hub stops recording high scores at 19:59 JST on August 15. The shop usually stays open for a short grace window so players who farmed on the last day can still trade. Brand New Summer set the pattern at six days. Confirm the exact Synchro close time in-game — do not assume the wiki can see your mailbox timer.
If the client shows items expiring soon, that warning is almost always leftover Event Badges, not Hololium or Lesson Points. Open the shop from the event banner, not from the generic item box.
Exchange priority (Synchro shop)
Community shop tables from the live event match this order. Stock and costs are per account; once a row hits its cap, it disappears.
| Item | Badge cost | Cap | Priority |
|---|---|---|---|
| Event Memory ×1 | 10,000 | 1 | Take first — unique park decoration |
| Hololium ×1 (first copy) | 10,000 | 1 | Take first — scarce limit-break material |
| Hololium ×1 (later copies) | 20,000 | 2 | High — still rare after launch month |
| Piece Box M ×1 | 350 | 20 | High — Memory Piece fodder |
| Crystal Box S ×1 | 300 | 30 | High — skill-board crystals |
| Lesson Points ×5,000 (first tier) | 100 | 50 | Medium — cheap Holomem Board fuel |
| Lesson Points ×5,000 (second tier) | 200 | 100 | Medium — buy after Hololium |
| Color Cubes ×5 / Core Cubes ×1 | 150 / 300 | 45 / 30 each color | Medium — fill the colors you actually train |
| Holo Gold ×10,000 | 100 | 50 | Low — farmable from Lives |
| Wood / nails / stone / paint / glass | 100–200 | 10–30 | Last — Dream Park mats drop from facilities |
Rule of thumb: unique and hard-to-farm first (memory, Hololium), then boxes, then Lesson Points for the colors you are building, then park junk if anything remains.
What no longer works after August 15
- Score-sum ranking is frozen. Extra clears on Sugar Rush, Kyun Kyun MIKO Kyun kyun ♡, or GHOST do not move your final place.
- AUTO scores never counted for ranking even while the event was live. Manual clears only.
- Match Cooking’s +50% event bonus applied during the campaign. After close, cook for park coins and personal bests, not badge multipliers.
- Live Boost ×3 and Holopass double-drop were event-week tools. Do not burn remaining boosts expecting Synchro badge rates.
Challenge songs stay in the library. Use them for normal material farms and for learning charts before the next Score Challenge.
Fifteen-minute spend routine (August 16)
- Open the Synchro banner → Exchange.
- Buy Event Memory and every Hololium you can afford.
- Dump leftover badges into Piece Box M and Crystal Box S until those rows grey out.
- Spend the rest on Lesson Points for the Holomem you still train — not on wood and glass.
- Screenshot the empty shop. If a countdown remains, check once more tomorrow.
Mailbox ranking rewards (titles, Diamonds, tickets) arrive after QualiArts tallies the ladder. They are separate from badge stock. Do not wait for mail before spending badges.

Frequently Asked Questions
Quick answers to the most common questions about hololive Dreams.
Did the Event Badge shop close when Synchro ended on August 15?
Ranking closed at 19:59 JST on August 15. The shop usually stays open for a short grace window — Brand New Summer badges lasted six more days, until August 11. Check the in-game countdown and spend Hololium and event memories first.
What should I buy first with leftover Synchro badges?
Event Memory (10,000, cap 1) and Hololium (10,000 then 20,000). After those, Piece Box M and Crystal Box S. Park materials like wood and glass are last.
Can I still farm Synchro badges on August 16?
Do not count on event drop rates after the score window. Spend what you already hold. Match Cooking and Lives still give park coins and materials, but the Synchro badge bonus is gone.
Is the miComet gacha part of the shop deadline?
No. The shop spends Event Badges. The Aim for Summer Together! gacha spends Diamonds and tickets through August 17, 10:59 JST.
