The MyCard TW Spring 2026 event runs February 9 through April 9, 2026 (midnight TST, UTC+8) across five games: Mobile Legends: Bang Bang, Tower of Saviors, Night Crows, Three Kingdoms: Clash of Heroes, and Lineage W. Top up during this window and you earn bonus diamonds — 10% at TWD 30, scaling to 30% at TWD 3000. That's the highest rate MyCard has offered in recent seasonal cycles. Every reward must be claimed before April 9. No extensions.
How the Milestone System Works
This isn't passive points accumulation. Each transaction is evaluated individually against the bonus tier table. A single TWD 3000 transaction earns 30% bonus. Three separate TWD 1000 transactions each earn only 20–25%. The system timestamps credit arrival, not when you initiate payment — so your transaction must fully process before April 9 midnight TST.
Bank transfers can take 1–24 hours to clear. In the final 48 hours before April 9, use e-wallet or FPX only.
MyCard TW does not extend seasonal deadlines. Plan as if April 9 is immovable, because historically it has been.
Full Bonus Tier Breakdown
Diamond ranges vary across games because MLBB, ToS, Night Crows, Three Kingdoms, and Lineage W each have slightly different base exchange rates.
TWD 3000 tier requires identity verification: legal name, National ID, date of birth, email, mobile number, address, 2FA OTP, and a 6-digit password. Complete this before February 9. Attempting it on event launch day under time pressure is how players lock themselves out of the top tier entirely.
Game-by-Game Highlights
Mobile Legends: Bang Bang
MLBB is the most reward-dense title in this event.
Promo codes (single-use per account, case-sensitive):2y3vo2r3x,0nc9lhok9,3r83efok9 — yields 112 diamonds total. Expire approximately February 23–March 9. Redeem immediately via the MyCard Payment Center or the in-game Events tab.
Task Master Lucky Draw runs February 13–26 only. This overlap window is the single best time to spend in MLBB — your TWD 3000 bonus stacks with Task Master rewards simultaneously.
Free diamond sources to exhaust before spending:
Weekly missions: 200–300 diamonds
Login rewards: 50–80 diamonds
Rank rewards: 400+ (Grandmaster) to 1,000+ (Mythic)
Community testing confirms this generates 8–12 pity draws before you spend anything
Pull cost reference:
Single pull: 45–50 diamonds
Standard 10-pull: 800–900 diamonds
Full pity pool: 2,000–3,000 diamonds
The Weekly Diamond Pass (220 diamonds: 80 immediate + 140 over 7 days, stackable up to 10x) had a purchase deadline of February 6, 2026.
Tower of Saviors
Sub-event runs February 16–March 15, 2026 (00:00–23:59 GMT+8), with rewards claimable through April 9.
750 MyCard points redeems for: 6 Diamonds + 800 Souls + 8M Coins + 1 Harpy. Redeemable up to 5 times — 3,750 points total for the full set.
Pool all 3,750 points and redeem all five tiers in a single session. Splitting across sessions has caused sync issues in past MyCard events. And with the March 15 sub-event close (not April 9), you have less buffer than you might assume.
Night Crows, Three Kingdoms & Lineage W
All three participate in the standard bonus tier structure. No confirmed sub-events at the MLBB/ToS level.
Lineage W guild players: community experience puts TWD 3000 as effectively mandatory for active guild diamond demands. Casual players across all three titles are better served by TWD 1000 — solid bonus, no identity verification overhead.
Step-by-Step Redemption
Step 1 — Verify identity (TWD 3000 targets only)
Do this before February 9. Required: legal name, National ID, date of birth, email, mobile number, address, 2FA OTP, 6-digit transaction password.
Step 2 — Time your top-up Don't top up before February 9 midnight TST — zero bonus on early transactions. For MLBB:
Redeem promo codes February 9 (112 free diamonds)
Exhaust free sources February 9–12
Execute TWD 3000 top-up February 13–26 (Task Master overlap)
Step 3 — Execute the top-up
Desktop (MyCard Payment Center): Enter serial number and password → select game → enter member ID and account password → confirm.
Mobile: More → Taiwan → MyCard → same game selection and member ID flow.
Payment method minimums:
Bank Transfer: TWD 150 (allow 1–24h — avoid in final 48h before April 9)
FPX: TWD 200
E-wallet / EC Pay: TWD 300
7-ELEVEN: TWD 500
Step 4 — Claim bonus diamonds Credited directly to your game account. Allow 2–24 hours. Diamonds are permanent once credited — no expiry. If nothing appears after 24 hours, verify your transaction timestamp falls within February 9–April 9 TST and that you're on a Taiwan-region account.
Step 5 — Redeem MLBB promo codes In-game: Events tab → enter code (case-sensitive) → select MLBB → enter member ID. Or use MyCard Payment Center directly. Do this before ~March 9.
The Stacking Window Most Players Miss
During February 13–26, a TWD 3000 MLBB top-up stacks with:
Task Master Lucky Draw rewards
E-wallet cashback of 2–3% (~TWD 60–90 back on TWD 3000)
Free diamonds from missions, logins, rank rewards already banked
112 promo code diamonds already in your account
This is the only window where all four bonus streams are simultaneously active for MLBB. If you're spending, this is when.
For ToS, the equivalent window is February 16–March 15 — sub-event period where points redemptions yield the full 5x reward set alongside the top-up bonus.
If you're planning a larger top-up to maximize the Spring 2026 bonus, MyCard (TW) top up best value 2026 is worth checking for competitive rates before committing to the TWD 3000 tier.
Spending Efficiency: Where Your TWD Goes Furthest
TWD 3000 vs. three TWD 1000 (same total spend):
3× TWD 1000 at 20–25% = 4,200–7,500 diamonds
1× TWD 3000 at 30% = 4,500–6,500 diamonds
Single transaction yields up to 500 more diamonds, plus one identity verification instead of three, plus preserved VIP tier efficiency.
TWD 1000 vs. three TWD 300 (same total spend):
3× TWD 300 at 15% = 1,200–1,800 diamonds
1× TWD 1000 at 20–25% = 1,400–2,000 diamonds
TWD 1000 beats splitting by 50–200 diamonds at identical cost. If you're not ready for TWD 3000, TWD 1000 is the rational floor.
The TWD 30 and TWD 90 tiers at 10% are the worst value in the event. They exist for casual dippers — but if you're reading a guide, you're not a casual dipper.
Troubleshooting
Bonus diamonds not appearing: Wait 2–24 hours. Confirm timestamp is within February 9–April 9 TST. Verify Taiwan-region account. Still missing after 24 hours? Contact MyCard TW support with your transaction ID.
Promo codes failing: Codes are case-sensitive and single-use. Already redeemed on this account = won't work again. If genuinely new and failing, check whether you're past the expiry window (~February 23–March 9).
TWD 3000 tier blocked: Almost always incomplete identity verification. No workaround — must be completed before the transaction. Contact MyCard TW support if verification is stuck in processing.
ToS points not syncing: Known issue when redemptions are split across sessions. Pool all 3,750 points and redeem all five tiers in one session before March 15. If sync issues occur mid-redemption, wait 30 minutes before retrying — don't submit multiple requests.
Bank transfer missed the deadline: If initiated within 24 hours of April 9 midnight and didn't clear, the bonus is gone. Initiation time is irrelevant; credit arrival is what counts.
After April 9
Unclaimed bonuses on unprocessed transactions are gone. The cutoff is a hard system close.
Bonus diamonds already credited before April 9 are permanent — identical to regular diamonds, no expiry. The deadline applies to earning bonuses, not spending diamonds you've already received.
Final checklist:
Identity verification completed (TWD 3000 targets)
MLBB promo codes redeemed (before ~March 9)
ToS points pooled and redeemed in single session (before March 15)
Top-up executed February 13–26 for MLBB stacking window
Final top-ups via e-wallet or FPX only in last 48 hours
Transaction ID saved for support escalation if needed
For players still deciding on top-up amount in the final days, buy MyCard (TW) spring bonus diamonds cheap to lock in before the April 9 cutoff.
FAQ
Can I participate in multiple games with one top-up? No. Each transaction is designated to a specific game at purchase. Separate transactions required for each title.
Do Spring 2026 exclusive items return in future events? Some cosmetics have reappeared in past MyCard seasonal cycles, but it's not guaranteed and hasn't been officially confirmed for Spring 2026. Treat limited-time exclusives as genuinely limited.
What payment methods count toward milestone progress? All qualifying methods (bank transfer, FPX, e-wallet, EC Pay, 7-ELEVEN) count, provided the transaction meets the method's minimum and processes before April 9 midnight TST. Payment method affects processing speed, not eligibility.
Why isn't my milestone progress updating? Allow 2–24 hours. If still not updated, verify your timestamp falls within the event window and your account is on a Taiwan-region server. Contact MyCard TW support with your transaction ID if it persists beyond 24 hours.
Is the event available to all MyCard TW holders? Available to all MyCard TW accounts, but the games are region-locked to Taiwan servers. International players need TW-server accounts — MyCard is not valid for non-Taiwan regional game accounts.
Can I stack MyCard points with the Spring 2026 top-up bonus? Yes. The 30% top-up bonus and MyCard points accumulation are separate systems running simultaneously. ToS players especially should leverage this — the sub-event's 750-points-per-redemption structure runs alongside the standard bonus tier, giving you two reward streams from a single top-up.
Spring 2026 is one of the more generous MyCard seasonal promotions in recent memory. The players who get the most out of it time their transactions deliberately, complete verification early, and don't split purchases unnecessarily. April 9 midnight TST is the line. Everything before it counts. Nothing after does.
