The MyCard Spring 2026 promotion ends April 9, 2026 at midnight Taiwan Standard Time (UTC+8) — and the top tier gives you a confirmed 30% bonus on a single TWD 3,000 top-up. Bonus diamonds credit immediately on qualifying transactions but require a manual claim through the MyCard Member Center before that hard cutoff. Miss the claim step and the bonus is gone. Here's exactly how to capture every percentage point before the window closes.
What the 30% Bonus Actually Is
This is a top-up incentive, not a spend incentive. Bonus diamonds are credited when you complete a qualifying transaction — not when you spend inside the game. Your strategy should focus entirely on when and how much you top up.
Bonus Tier Breakdown
Community testing confirms a single TWD 3,000 top-up yields roughly 4,500–6,500 diamonds, versus approximately 4,200–6,000 diamonds from splitting the same budget across three TWD 1,000 transactions at 20–25%. That's up to 500 extra diamonds for one large transaction over multiple smaller ones — a real gap if you're chasing gacha pity or a battle pass.
The Deadline, Precisely
April 9, 2026, midnight TST (UTC+8) = 4:00 PM UTC = 12:00 PM EDT. No grace period. No retroactive processing. No extensions.
Two things must happen before that moment: your transaction must fully clear, AND you must manually claim the bonus in the MyCard Member Center. Both steps. One missed step means forfeited rewards.
Step 1 — Confirm Eligible Games First
Topping up for an ineligible game or unlinked account is the most common way players lose their bonus entirely. Verify first, spend second.
Officially confirmed eligible titles — Taiwan servers only:
Mobile Legends: Bang Bang (MLBB)
Tower of Saviors (ToS)
Night Crows
Three Kingdoms: Clash of Heroes
Lineage W
The Taiwan server restriction is non-negotiable. If your account is on a non-Taiwan regional server, the bonus won't apply — even if the game is on the eligible list. Check your server region in account settings before initiating anything.
Cross-reference against the official MyCard promotion page at pay.mycard.com.tw before topping up. That page is the ground truth if anything changes in the final days.
Step 2 — Calculate the Right Amount
Competitive players with the budget: TWD 3,000 in a single transaction is the clear optimal choice. Casual players: TWD 1,000 at 20–25% still delivers strong value without over-committing.
The Math in Plain Numbers
TWD 3,000 at 30%: You're getting TWD 3,900 worth of currency for TWD 3,000 spent. That's TWD 900 in free diamonds.
TWD 1,000 at 20–25%: You're getting TWD 1,200–1,250 worth of currency. Solid, but lower per-dollar efficiency.
Splitting TWD 3,000 into three TWD 1,000 transactions: You lose up to 500 diamonds versus the single large transaction. Community consensus is clear — single large top-up beats splits every time.
Should You Stretch Your Budget?
Honest answer: if you're a competitive player who'll use the diamonds within the next few months, yes. The 30% efficiency gain is real, and bonus diamonds carry no separate expiry once credited. If you're casual and might not burn through a large balance for months, TWD 1,000 at 20–25% is the smarter, lower-risk call. And if free-to-play resources are covering your current needs, there's no obligation to spend at all.
Step 3 — Top Up Before the Deadline
Use instant payment methods only on the last day. Bank transfers can take 1–24 hours. 7-ELEVEN physical cards carry same-day processing risks. On April 7 or later, those methods are genuinely dangerous for deadline compliance.
Payment Method Risk Assessment
Official minimums: bank TWD 150, FPX TWD 200, e-wallet TWD 300, 7-ELEVEN TWD 500.
For a fast, fully online top-up without a convenience store trip, buy MyCard (TW) cheap price through BitTopup — instant e-wallet and FPX options that are specifically reliable in the final 48-hour window.
The Official Process, Step by Step
Log in to your MyCard TW account at pay.mycard.com.tw
Link your Taiwan-region game account to your MyCard profile
Complete identity verification (required for TWD 3,000 tier — do this before the last day)
Top up via FPX or e-wallet
Immediately open MyCard Member Center and manually claim your bonus
Step 5 is where players most often fail. The bonus doesn't auto-apply. Community testing suggests initiating your final top-up by 11:45 PM TST at the latest, allowing processing time, then claiming in Member Center right after confirmation.
Pre-verify your identity and link your game account well before April 9. Both steps can introduce unexpected delays if left to the last hour.
Step 4 — Spend Where the Bonus Goes Furthest
Getting the bonus is half the equation. Where you spend it determines whether that 30% translates into real progress.
MLBB: Best Stacking Window
For Mobile Legends players, the MLBB Task Master Lucky Draw event (Feb 13–26) is the confirmed optimal stacking window — combining the 30% MyCard bonus with an active in-game event for a genuine multiplier effect. Gacha pity systems, battle passes, and diamond packs are the highest-value targets. If you're in high-rank competitive play or active guild content, this is where the bonus goes furthest.
Tower of Saviors: Sub-Event Stacking
ToS has a confirmed sub-event running Feb 16–Mar 15: accumulate 3,750 points (in 5x 750-point increments) for rewards including 6 diamonds, 800 souls, 8M coins, and 1 Harpy — all claimable by April 9. Stack your MyCard top-up with this sub-event for compounded value.
Spending Priority by Content Type
One thing most guides skip: bonus diamonds are functionally identical to regular diamonds — same purchasing power, no restrictions, no separate expiry. Spend them exactly as you would base currency.
Last-Day Mistakes That Cost Real Money
These aren't hypothetical. They're patterns from previous MyCard bonus events, confirmed by community testing.
Bank transfer or 7-ELEVEN on April 8–9. A transfer initiated at 10 PM on April 8 can easily process after midnight. Transaction clears, event has ended, no bonus. Use FPX or e-wallet exclusively in the final 48 hours.
Topping up a non-Taiwan server account. MLBB on the Southeast Asia server won't receive the bonus even though MLBB is on the eligible list. Check your server before spending anything.
Skipping the Member Center claim. Players who top up at 11:58 PM and forget to open Member Center lose everything. Do it immediately after your transaction confirms.
Waiting until the absolute last minute. Server load increases near midnight on deadline days. A transaction that normally takes 2 minutes might take longer. The 11:45 PM guideline exists for this reason.
Skipping identity verification until the last day. The TWD 3,000 tier requires it. If you haven't done this before April 9, the verification process itself might push you past the deadline.
What Happens to Your Balance After April 9?
Good news: bonus diamonds credited before the deadline are permanent. Once they're in your linked game account, they carry no separate event expiry — identical to base currency in every way.
What's forfeited after midnight: unclaimed Member Center rewards, and any pending transactions that haven't fully processed. A transaction still processing at 12:01 AM on April 10 completes as a regular top-up with no bonus applied.
Miss the window entirely? Already-credited diamonds are safe. New top-ups after April 9 simply receive no Spring 2026 bonus. No penalty, no clawback.
For last-minute top-ups, MyCard (TW) best deal options through BitTopup let you top up quickly without convenience store stress.

Frequently Asked Questions
When exactly does the bonus end?
April 9, 2026 at midnight TST (UTC+8) — 4:00 PM UTC / 12:00 PM EDT. Both your transaction and your Member Center claim must complete before this moment. No grace period, officially confirmed.
Is the bonus credited automatically?
No. The top-up triggers the bonus, but you must log into the MyCard Member Center and manually claim it after your transaction processes. This two-step process catches a lot of players off guard on deadline day.
Which games are confirmed eligible?
MLBB, Tower of Saviors, Night Crows, Three Kingdoms: Clash of Heroes, and Lineage W — Taiwan servers only. Cross-check against the official MyCard promotion page before topping up.
Can I stack the MyCard bonus with in-game events?
Yes — and this is where the real value multiplier lives. MLBB's Task Master Lucky Draw (Feb 13–26) and ToS's sub-event (Feb 16–Mar 15) are confirmed stacking opportunities. Timing your top-up to coincide with active in-game events compounds the effective value significantly.
Do bonus diamonds expire separately?
No. Once credited to your linked game account, bonus diamonds are permanent and identical to base currency. The April 9 deadline governs when you can earn the bonus, not how long you can use it.
Is it worth topping up more than planned to hit the 30% tier?
For competitive players: yes, if you'll use the diamonds. A single TWD 3,000 transaction at 30% delivers up to 500 more diamonds than splitting the same budget across smaller tiers. For casual players who won't burn through a large balance, TWD 1,000 at 20–25% is the smarter call. The bonus is genuinely strong — the question is whether your playstyle justifies the spend.
