The MyCard TW Spring 2026 campaign runs February 9 to April 9, 2026 (midnight TST, UTC+8) — and that deadline is absolute. Eligible games: MLBB, Tower of Saviors, Night Crows, Three Kingdoms: Clash of Heroes, and Lineage W. The headline reward is a 10–30% bonus diamond on top-ups, scaling up to TWD 3000 for 4500–6500 diamonds. Three confirmed MLBB promo codes add 112 free diamonds on top. Stack everything correctly and you're pulling significantly more currency than any standard top-up would yield.
What You Need to Know Before April 9
April 9 midnight TST is a hard cut-off. Rewards in your MyCard Member Center inbox don't auto-deliver — you must manually claim them before the deadline or they're gone permanently.
The Tower of Saviors sub-event closes March 15 — nearly a month before the main deadline. That's the most common mistake players make: assuming April 9 covers everything.
What's permanently lost after April 9: unclaimed Member Center rewards, unredeemed top-up milestone bonuses, unspent event points. What's safe: diamonds already credited to your in-game account. Note that MyCard terminates zero-balance accounts after 6 months of inactivity — worth keeping in mind for long-term account health.
Eligibility
Your physical location doesn't matter. You need a Taiwan-region game server account and a MyCard account registered to TW. International players participate successfully — community testing confirms this consistently. New MLBB accounts may need a few matches before promo code redemption unlocks, so don't wait until April 8 to set up a fresh account.
All Confirmed Spring 2026 Promo Codes
Three MLBB codes are officially confirmed, redeemable from February 9 with 2–4 week expiry windows. Single-use per account.
Any additional codes circulating in community forums are unverified until confirmed by official MyCard or Moonton channels.
How to Redeem
Desktop (pay.mycard.com.tw):
Log in and navigate to the promo code redemption section
Enter the code exactly as shown — case-sensitive
Select MLBB as your game
Enter your MLBB Member ID and confirm
In-game (faster if already logged in): Profile → Events → Redeem Code
Mobile app: More → Taiwan Region → MyCard Point Card → Enter Code/Password → Top-Up
Troubleshooting
Invalid code error: Copy-paste directly rather than typing — the codes mix numbers and lowercase letters
Code applied, no diamonds: Wait up to 2 hours during high-traffic periods; verify email verification is complete and you're on a TW-server MLBB account
Region lock error: Your MyCard account must be TW-region registered; a non-TW account can't redeem these regardless of game server
Bonus Diamonds: How the Tiers Work
Top-Up Milestone Tiers
The consolidation math is clear: one TWD 3000 top-up yields 4500–6500 diamonds; three separate TWD 1000 top-ups yield 4200–6000 — up to 500 diamonds less for the same spend. If you're planning a large top-up, don't split it.
The TWD 3000 tier requires full identity verification: name, national ID, date of birth, email, mobile number, address, 2FA OTP, and a 6-digit payment password. Start this early — support queues spike around February 9 and again in the final week before April 9.
Stacking: What Combines With What
This is the detail most guides skip. Community testing confirms the 30% MyCard bonus stacks with all of the following simultaneously:
MLBB Task Master Lucky Draw (Feb 13–26)
Tower of Saviors sub-event rewards
MLBB Weekly Diamond Passes
E-wallet/EC Pay cashback (typically 2–3%)
112 promo code diamonds (additive on top of top-up yield)
There's no confirmed stacking cap. These are separate systems that don't interfere with each other. Most players activate one or two layers. The difference between one layer and all five is hundreds of diamonds.
For players planning a MyCard (TW) Spring 2026 top up bonus deal before April deadline, timing your top-up within the Task Master window (Feb 13–26) is the single highest-leverage decision you can make.
Step-by-Step Mission Walkthrough
MLBB: Optimal Sequence
February 9: Redeem all three promo codes immediately (112 diamonds, zero cost)
February 9–12: Stack free sources — weekly missions (200–300 diamonds), login bonuses (50–80 diamonds), ranked rewards (Grandmaster: 400+, Mythic: 1000+)
February 13–26: Execute your TWD 3000 top-up during the Task Master Lucky Draw window
Timing matters here. Top up before February 13 and you miss the Task Master stacking window. Top up after February 26 and that bonus layer is gone.
Tower of Saviors Sub-Event (Feb 16 – March 15)
750 MyCard points redeems for 6 Diamonds + 800 Souls + 8M Coins + 1 Harpy, limit 5 redemptions (3,750 points total).
The mistake players make: drip-redeeming one reward at a time across multiple sessions, then missing the March 15 deadline. The correct approach — pool all 3,750 points and redeem all five in a single session before March 15. Don't let the April 9 main deadline create false security about this earlier cut-off.
MLBB Weekly Diamond Pass
If you purchased the Weekly Diamond Pass before February 6, 2026: each pass delivers 80 diamonds immediately plus 20 diamonds daily for 7 days (140 total per pass, stackable up to 10x). Collect daily rewards without fail — these stack with the Spring event bonus.
Collecting Rewards
Rewards are not automatic. After every qualifying mission or top-up, go to MyCard Member Center → Reward Inbox and manually claim each reward. Many players discover unclaimed rewards only after the deadline has passed.

Is It Still Worth Topping Up in the Final Days?
Yes. A TWD 3000 top-up at 30% bonus yields 4500–6500 diamonds versus the 3000–3500 you'd get outside an event. The math favors acting before April 9 over waiting for the next campaign — especially if you're building toward pity in MLBB (first discounted pull: 45–50 diamonds; standard pull: 90–100; 10-pull guarantee: 800–900 total; full pool: 2000–3000 diamonds).
F2P players: exhaust free sources first. Weekly missions (200–300 diamonds), login bonuses (50–80), and ranked rewards (400+ at Grandmaster, 1000+ at Mythic) advance your pity counter and reduce total spend needed to hit a guarantee.
Troubleshooting
Bonus not appearing after top-up: Wait 2 hours before escalating. Verify your top-up timestamp is after February 9, you're checking the correct linked game account, and you've checked the Member Center inbox — not just your in-game wallet. If nothing after 2 hours, contact support with your transaction ID ready. That single piece of information cuts resolution time dramatically.
Promo code applied, no diamonds: Confirm email verification is complete on your MyCard account. Verify you selected MLBB and entered the correct Member ID. Still nothing after 2 hours — contact support with the code used and your Member ID.
ToS rewards not tracking: The sub-event runs February 16 – March 15 only. Outside that window, the system won't process redemptions. Within the window, confirm you have minimum 750 points per redemption and your ToS account is properly linked to MyCard.
Missions not tracking: Pre-load your MyCard Wallet on weekday mornings before 11 AM TST — server load is lowest then. Community experience consistently shows fewer tracking failures at off-peak hours compared to peak-hour top-ups.
Frequently Asked Questions
Do unclaimed rewards disappear permanently after April 9? Yes. Rewards in your Member Center inbox that haven't been manually claimed are gone after April 9 midnight TST. Diamonds already credited to your in-game account before the deadline are safe with no expiry. The deadline applies to the claiming step, not just the earning step.
Are the promo codes single-use or multi-use? Single-use per account. Each of the three codes can be redeemed once per MyCard account — they can't be reused or shared between accounts.
Can I participate from outside Taiwan? Yes. Physical location is irrelevant — you need a TW-region MyCard account and a TW-server game account. Payment method minimums apply regardless of location: Bank Transfer TWD 150, FPX TWD 200, E-wallet/EC Pay TWD 300, 7-ELEVEN TWD 500.
What's the maximum bonus available? The TWD 3000 tier yields 4500–6500 diamonds (30% bonus). Add 112 from promo codes, plus Weekly Diamond Pass and Task Master rewards. There's no single ceiling figure since stacking sources vary by player, but a fully optimized TWD 3000 top-up with all layers active is the maximum achievable.
Why does the ToS sub-event end March 15 if the main event runs to April 9? It's a separate promotion with its own timeline nested within the broader Spring 2026 campaign. Missing March 15 means losing those ToS rewards even though the main event continues for three more weeks.
Top-up processed but bonus is missing — fastest fix? Check the Member Center inbox first (rewards aren't auto-delivered). Nothing there after 2 hours — contact support immediately with your transaction ID. Don't wait; support queues grow significantly in the final week before April 9.
Event details reflect officially confirmed information as of the Spring 2026 campaign launch. Community-observed stacking behaviors are noted as such. Check the official MyCard TW platform for any deadline extensions or additional promo code releases closer to April 9.
