Campaign ends April 9, 2026. MyCard Taiwan's Spring's 100 Kinds of Surprises promotion gives you 10%–30% bonus diamonds on top-ups from TWD 30 to TWD 3000. The max 30% bonus hits at the TWD 3000 tier — that's up to 6,500 diamonds from a single recharge. Taiwan-region accounts only. Bonus diamonds credit in 2–5 minutes via instant payment. No grace period after April 9.
What Is the MyCard Taiwan Spring Campaign 2026?
Unlike standard flat-rate top-ups, this seasonal promotion layers an extra 10%–30% bonus on every qualifying recharge depending on your tier.
Bonus Diamond Tiers vs. Standard Top-Up
TWD 30: Standard ~36 → Campaign 40–60 diamonds
TWD 90: Standard ~108 → Campaign 120–180 diamonds
TWD 300: Standard ~360 → Campaign 400–600 diamonds
TWD 1000: Standard ~1,200 → Campaign 1,400–2,000 diamonds
TWD 3000: Standard ~3,600 → Campaign 4,500–6,500 diamonds ← max 30% bonus
At TWD 3000, that's 2,000 extra diamonds at zero additional cost — purely from timing your top-up inside the campaign window.
Bonus diamonds function identically to standard diamonds. No in-game spending restrictions. Your MyCard portal balance reflects the combined total.
Key Dates and Deadlines
Campaign launch: February 9, 2026 (associated promo codes carry 2–4 week expiry from this date)
Hard deadline: April 9, 2026, midnight Taiwan Standard Time (TST, UTC+8)
UTC+0 equivalent: April 9 at 16:00 UTC
Any recharge after the campaign closes processes at standard rates — no bonus, no exceptions. Top-ups initiated before the deadline but delayed by processing may not qualify. Complete your final top-up at least 60–90 minutes before midnight TST on April 9, especially during peak traffic when even instant methods can take 30–60 minutes.
Eligibility Requirements
Taiwan-region MyCard accounts only. No workaround exists for accounts registered under other regions — the bonus simply won't apply.
You'll also need:
Valid MyCard member account login (good standing)
Payment password for transaction confirmation
Optionally, a registered mobile number for SMS confirmation
New Taiwan-region accounts registered before April 9 are eligible. No minimum account age confirmed.
Top-Up Strategy: How to Maximize Your Bonus
Single Large Recharge Beats Multiple Small Ones
Each transaction is evaluated independently at its own tier. Three TWD 1000 top-ups don't combine for a higher rate — each gets the bonus for its individual amount. Single higher-tier recharges are always the smarter play.
Which Tier Is Best?
Best value: TWD 3000 — up to 30% bonus, 6,500 diamonds
Second best: TWD 1000 — better rate than multiple smaller top-ups
Minimum entry: TWD 30 — qualifies, but bonus rate is lowest in the 10%–30% range
Pro tip: Stack your recharge bonus with up to 112 free diamonds from promotional codes for an additional layer of value during the campaign window.

Common Mistakes to Avoid
Myth: Any tier gets 30% bonus Wrong. The 30% maximum is exclusively at TWD 3000. Lower tiers receive proportionally smaller bonuses within the 10%–30% range.
Myth: Bonus diamonds have spending restrictions No confirmed restrictions. Bonus diamonds spend identically to standard diamonds in supported titles.
Myth: You can stack all promotions simultaneously Promo code bonuses (up to 112 free diamonds) can supplement your top-up. But stacking multiple campaign bonuses simultaneously isn't confirmed. Treat each bonus source independently.
Biggest mistake: Waiting until April 9 Peak deadline traffic routinely pushes processing to 30–60 minutes even for instant methods. A top-up at 11:45 PM TST on April 9 is a real gamble. Finish at least 60–90 minutes before midnight TST.
If Your Bonus Diamonds Don't Appear
Expected Timeframes
Instant payment methods: 2–5 minutes
Store/bank transfers: 15–60+ minutes
Peak period delays: up to 30–60 minutes for any method
Escalation threshold: 30 minutes for instant methods
Troubleshooting Checklist
Before contacting support, verify:
Account is registered under Taiwan region
Top-up amount met the minimum qualifying tier
You selected Taiwan as payment region during checkout
Transaction shows completed (not pending) in payment history
You're checking the correct MyCard account balance
If everything checks out and diamonds are still missing after 30 minutes, contact MyCard support with your transaction ID, top-up amount, timestamp, and account details. For BitTopup transactions, include your BitTopup confirmation as supporting documentation.
Smart Spending: What to Do With Your Bonus Diamonds
Best uses:
Limited-time in-game events running concurrently with the Spring Campaign
High-value permanent unlocks (characters, skins, equipment) with long-term utility
Bundle purchases offering additional in-game value multipliers
Save or spend immediately? No confirmed post-campaign expiry for bonus diamonds credited before April 9. But since promo codes from February 9 carry 2–4 week expiry windows, verify your specific bonus terms in the MyCard portal. When expiry terms are unclear, spending sooner reduces forfeiture risk.
Pro tip: Align large diamond spends with in-game events that offer their own bonus multipliers. You're effectively stacking the Spring Campaign's top-up bonus with event-specific spending bonuses inside the game — dual-layer value on every TWD spent.
