The MyCard TW Spring 2026 event runs February 9 to April 9, 2026 (midnight Taiwan Standard Time, UTC+8). Top up between TWD 30 and TWD 3000, get 10–30% bonus diamonds. Simple mechanic — but two deadlines trip people up every cycle: your top-up transaction must clear before April 9 midnight TST, and you must manually collect your bonus from MyCard Member Center before that same cutoff. Miss either one, you forfeit the bonus entirely.
How the Bonus Tiers Work
The bonus is denomination-locked, not a sliding scale. The 30% tier is only available at TWD 3000.
Ranges reflect variation across participating games — MLBB and Lineage W tend toward the higher end.
Participating titles: Mobile Legends: Bang Bang (MLBB), Tower of Saviors (ToS), Night Crows, Three Kingdoms: Clash of Heroes, Lineage W.
Tower of Saviors sub-event runs on a tighter schedule: February 16–March 15, 2026. Rewards still claimed via Member Center before April 9.
Eligibility
Any active MyCard TW member account linked to a Taiwan-region game server qualifies. Your physical location doesn't matter — overseas players with Taiwan-server accounts are fully eligible. What matters is the server region, not where you're sitting.
The TWD 3000 tier requires full identity verification before the transaction will process:
Full legal name, National ID number, date of birth
Email, mobile number, residential address
Two-factor authentication (2FA OTP)
6-digit payment password
Complete this before February 9. Support queues spike on launch day, and a delayed verification means missing early-event windows like MLBB Task Master.
Payment Method Minimums
All methods technically qualify for TWD 3000 — but timing matters enormously near the deadline (more below).
How to Claim: Step-by-Step
Two distinct phases: the top-up transaction, then reward collection. Both before April 9 midnight TST.
Desktop
Log in at mycard.com.tw
Navigate to the Spring 2026 Event Page (活動頁面) via the homepage banner
Select your denomination — TWD 3000 for the 30% bonus
Choose payment method; confirm the bonus percentage shows on the checkout screen
Complete the transaction and save your receipt/transaction ID
Go to MyCard Member Center and manually collect your bonus diamonds
Mobile App
The event page is under the 活動 (Events) tab in the bottom nav bar — not the homepage banner. That's the detail most guides miss.
Tap the Spring 2026 event card
Select denomination and payment method
Authenticate with your 6-digit password and 2FA OTP (required at TWD 3000)
After confirmation, tap 領取獎勵 (Claim Reward) in the Member Center section
E-wallet payments process faster on mobile than desktop in community testing — useful if you're cutting it close.
Verifying Credit
Check both your MyCard diamond balance in Member Center and your in-game currency wallet. During high-traffic periods, allow up to 2 hours before contacting support. If the top-up appears in your transaction history but diamonds haven't moved, the issue is on the claim side, not the payment side.
The April 9 Deadline — Read This Carefully
Both your top-up transaction and your bonus claim must complete before April 9, 2026, midnight TST (4:00 PM UTC). This is not a 48-hour claim window after purchase. Top up at 11:58 PM and your payment takes 30 minutes to clear? You're outside the event window. No bonus.
Pending bank transfers that haven't cleared by midnight don't get the bonus. The base diamonds still arrive — you just lose the percentage. Officially confirmed behavior, not a glitch.
Last-minute strategy: Use instant digital payments in the final 48 hours. E-wallet and EC Pay clear in 2–5 minutes. Bank transfers initiated after 3 PM TST can take 1–24 hours — not a risk worth taking in the final week.
Pre-loading your MyCard Wallet on weekday mornings before 11 AM TST minimizes processing delays throughout the event.
Maximizing Your Bonus: The Math
Why TWD 3000 Beats Splitting
|
ifference | Up to 500 more | Same cost |
Same budget, up to 500 extra diamonds. For competitive MLBB or Lineage W guild players, that gap is real. Casual players who don't need 3000+ diamonds in one cycle can reasonably stop at TWD 1000 — the 20–25% bonus is still solid value.
If you want a reliable way to fund your MyCard balance, the MyCard TW Spring 2026 top up discount deal at BitTopup is worth checking before you commit to a denomination.
What Stacks With the 30% Bonus
Community testing across multiple accounts confirms these stack independently:
MLBB Task Master Lucky Draw (February 13–26, 2026)
Tower of Saviors sub-event (February 16–March 15, 2026)
MLBB Weekly Diamond Pass — 220 diamonds (80 immediate + 20 daily × 7), stackable up to 10×; purchase before February 6 for optimal overlap
Payment cashback from certain E-wallets (typically 2–3%)
MLBB promo codes
2y3vo2r3x,0nc9lhok9,3r83efok9— 112 diamonds total, single-use, expire 2–4 weeks after February 9
Redeem the promo codes on day one via the in-game Events tab. 112 free diamonds is roughly one gacha draw at zero cost — don't treat it as a footnote.
Optimal MLBB Sequence
February 9: Redeem all three promo codes (112 diamonds)
February 9–12: Stack free draws from weekly missions (200–300 diamonds) and login rewards (50–80 diamonds)
February 13–26: Execute TWD 3000 top-up during Task Master Lucky Draw window
Ongoing: Collect ToS sub-event rewards before March 15; claim all Member Center rewards before April 9
F2P players should exhaust free sources first — missions, login streaks, and rank rewards (Grandmaster: 400+ diamonds, Mythic: 1000+) can yield 8–12 draws before any spending.
Game-Specific Tier Recommendations
Troubleshooting: Bonus Not Appearing?
Crediting times: Instant to 15 minutes for E-wallet/EC Pay under normal conditions. Up to 2 hours during high-traffic periods. Bank transfers: 1–24 hours.
Wait the full 2 hours during busy periods before opening a ticket.
If payment processed but no bonus:
Screenshot your MyCard transaction history with the payment timestamp
Screenshot your in-game diamond balance before and after
Confirm the timestamp falls between February 9 and April 9 TST
Submit to MyCard TW support with both screenshots and your member ID
Support resolution takes longer in the final week — another reason to avoid last-minute top-ups.
Common Mistakes to Avoid
Topping up before February 9. Timezone confusion catches overseas players constantly. Midnight TST on February 9 is the open, not the close.
Skipping verification until top-up day. Launch day support queues are long. Complete all 7 verification fields at least a week early.
Splitting TWD 3000 into smaller transactions. Three TWD 1000 top-ups cost the same but yield up to 500 fewer diamonds. The math doesn't favor splitting.
Drip-redeeming ToS rewards. Players who redeem one at a time risk hitting the March 15 sub-deadline mid-session. Pool all 3,750 MyCard points and redeem all five reward sets in one go.
For players coordinating a large TWD 3000 transaction near the deadline, checking MyCard TW cheap recharge bonus diamonds buy online at BitTopup beforehand is a practical step.
FAQ
Can I claim the 30% bonus more than once? Yes — the bonus applies per qualifying transaction. Multiple TWD 3000 top-ups during the event window each earn 30%. No stated cap per account.
Does April 9 apply to purchase or claim? Both. Transaction must clear AND you must manually collect from Member Center — all before April 9 midnight TST.
Why didn't my bonus appear after topping up during the event? Check your transaction timestamp first. Most common causes: transaction cleared before February 9, bank transfer still pending, bonus not manually claimed from Member Center, or incomplete verification for the TWD 3000 tier.
Does the 30% bonus stack with the MLBB Weekly Diamond Pass? Yes, confirmed across multiple accounts. They operate independently. Buy the pass before February 6 for optimal overlap.
What if I top up the wrong game account? Contact MyCard TW support immediately with your transaction ID and both account details. Resolution isn't guaranteed once diamonds are credited to the wrong account. Double-check your linked account before checkout — especially on mobile where autofill can populate old IDs.
Are bonus diamonds the same as regular diamonds? Yes. Once credited, they function identically in every participating game. No separate wallet, no usage restrictions.
Contacting MyCard TW Support
Use the official mycard.com.tw support portal. Have ready:
MyCard member ID and transaction ID with timestamp
Screenshots of your transaction history and in-game diamond balance
The specific game and server region
Email and the official ticket system create a documented paper trail — live chat doesn't. Submit early in the week, not on the final day. Support volume spikes hard in the last week of the event.
The 30% bonus is one of the better seasonal promotions for Taiwan-server players. One TWD 3000 top-up beats splitting the same budget every time. Finish verification early, use instant payments near the deadline, stack with in-game events, and manually claim from Member Center — all before April 9 midnight TST. The sequence isn't complicated. It just has to be done in order.
