The MyCard TW Spring 2026 promotion runs February 9 to April 9, 2026 (midnight Taiwan Standard Time, UTC+8). Top up on eligible games and earn 10–30% bonus diamonds — but only if you hit the right spend threshold in a single transaction. Miss the deadline or split your purchase wrong, and you forfeit every extra diamond.
What Is This Promotion?
MyCard Taiwan's seasonal top-up event covers five games on Taiwan-region servers only:
Mobile Legends: Bang Bang (MLBB)
Tower of Saviors (ToS)
Night Crows
Three Kingdoms Clash of Heroes
Lineage W
Wrong region? The bonus won't trigger — no error, no warning. Your account must be linked to a TW-server game client, and your MyCard account must be registered to Taiwan.
The 30% bonus is permanent once claimed. No expiry, no secondary timer. But you have to actively meet spend thresholds, complete verification, and manually claim the bonus before April 9 midnight TST.
Bonus Tier Breakdown
Core rule: bonuses are per-transaction, not cumulative. Three TWD 1,000 purchases do NOT equal one TWD 3,000 purchase.
Splitting a TWD 3,000 budget into three TWD 1,000 top-ups costs you real diamonds. Three TWD 1,000 transactions yield roughly 4,200–6,000 diamonds total. One TWD 3,000 transaction yields 4,500–6,500. That's up to 500 diamonds lost by splitting — enough for a meaningful gacha pull in most eligible titles.
The TWD 30/90 tiers aren't worth it even on a tight budget. Save for a single TWD 300 purchase instead.
How to Maximize Your 30% Bonus: Step by Step
Step 1 — Verify Your Account
Log in at mycard.com.tw or the MyCard app. Confirm your account links to a Taiwan-region game server. Wrong-server linking is one of the most common reasons bonuses don't apply.
Step 2 — Complete Identity Verification First
The 30% tier requires full verification before you transact. You'll need:
Legal name and National ID number
Date of birth
Email, mobile number, residential address
2FA OTP and 6-digit password
Don't leave this for the last day. If verification isn't complete when you make the purchase, you automatically drop to a lower tier — no exceptions.
Step 3 — Choose Your Top-Up Method
For players looking to stretch their budget, MyCard (TW) discount deal 2026 via BitTopup offers discounted MyCard TW PIN codes at approximately 40% off — and these codes fully qualify for the Spring 2026 bonus. That combination (discounted code + 30% bonus) is the highest total value available during this window.
If you're topping up near April 9, use instant payment methods only — e-wallet or FPX. Bank transfers may not clear before midnight. A transaction initiated before the cutoff but not yet processed does not count.
Step 4 — Make One Single Top-Up
One TWD 3,000 transaction. Don't split it. This is the single most important mechanical detail of the entire promotion.
Step 5 — Manually Claim Your Bonus
Bonus diamonds credit to your MyCard wallet or in-game inbox within 2–24 hours. They are not automatically applied — you must claim them from the Member Center or in-game inbox. This claim must happen before April 9 midnight TST, even if your top-up was processed days earlier. Unclaimed bonuses are forfeited at the deadline.
Step 6 — Spend Deliberately
Once claimed, bonus diamonds are permanent. No expiry. Plan your pulls and upgrades instead of spending reactively.
Best Games for Spring 2026 Bonus Diamonds
MLBB offers the strongest value. Layer the 30% top-up bonus with the Task Master Lucky Draw (February 13–26), weekly mission rewards, rank rewards, and the Diamond Pass simultaneously. Competitive MLBB players and Lineage W guild members get the most mileage from the TWD 3,000 tier.
Three MLBB promo codes are also available: 2y3vo2r3x, 0nc9lhok9, and 3r83efok9 — each worth 112 diamonds, redeemable via pay.mycard.com.tw or in-game after email verification on a TW-server account. Redeem these right after February 9. Free diamonds, no additional spend required.
Tower of Saviors has a sub-event: up to 5 redemptions, each costing 750 MyCard points and yielding 6 diamonds, 800 Souls, 8M Coins, and 1 Harpy. Accumulation runs to March 15; claim deadline is still April 9. Redeem all 5 in a single session to avoid sync issues.
April 9 Deadline: Two Traps to Avoid
Hard cutoff: April 9, 2026, midnight TST (UTC+8). No extensions, no grace periods, no retroactive credits.
Trap 1 — Payment processing timing. A bank transfer initiated at 11:50 PM on April 9 almost certainly won't clear before midnight. Use instant payment methods exclusively in the final 48 hours. If the payment isn't fully processed before cutoff, it doesn't qualify — regardless of when you initiated it.
Trap 2 — Forgetting to claim. Your top-up can be processed days before April 9, but if you don't manually claim the bonus from your Member Center or in-game inbox, you lose it at midnight. Set a reminder. This is a separate action from the top-up itself.
Once claimed, bonus diamonds are permanent. The April 9 deadline applies to the claiming action only.
If your bonus hasn't appeared within 24 hours of a completed top-up, contact MyCard support with your transaction ID. Support queues grow significantly near the deadline — don't wait until April 8 to report a problem from April 1.
Common Mistakes That Cost Players Diamonds
Splitting purchases. Already covered — three TWD 1,000 top-ups lose you up to 500 diamonds versus one TWD 3,000 top-up. The tier is per-transaction. Splitting is always a net loss at the 30% tier.
Topping up before February 9 or on the wrong server. Pre-window purchases don't qualify retroactively. Neither do top-ups on non-TW servers. Zero bonus, no recourse.
Skipping verification before the TWD 3,000 purchase. Verification is a prerequisite, not a post-purchase formality. Incomplete verification at transaction time means you drop to a lower tier automatically.
Forgetting to manually claim. The most avoidable mistake. Bonus diamonds sit in your Member Center or in-game inbox until you claim them — and disappear at April 9 midnight if unclaimed.
Using slow payment methods near the deadline. Bank transfers on April 8–9 are a gamble. Instant methods only.
One practical note from community experience: pre-load your MyCard wallet on weekday mornings when server load is lower. The portal slows significantly near promotional deadlines, and the mobile app tends to be more stable than the web portal under load.

FAQ
How does the bonus stacking work? Per-transaction, not cumulative. One TWD 3,000 top-up earns 30%. Three TWD 1,000 top-ups each earn 20–25% — you can't combine them to reach the 30% threshold.
Do bonus diamonds expire after April 9? No. Once claimed before the deadline, they're permanent. The April 9 cutoff applies to the claiming action only.
Can I split my top-up and get the same total bonus? No. Splitting costs you up to 500 diamonds at the TWD 3,000 tier. Community testing confirms this consistently.
My bonus diamonds didn't appear — what now? Wait up to 24 hours. Still missing? Contact MyCard support with your transaction ID. Don't wait until April 8 to report a problem from April 1.
Which game gives the best value? MLBB, by a clear margin. The 30% bonus stacks with Task Master Lucky Draw, weekly missions, rank rewards, and the Diamond Pass simultaneously. Lineage W is second for guild-active players.
Does this work for both mobile and PC? Yes — eligible titles include mobile (MLBB, ToS, Night Crows) and PC-accessible clients (Lineage W, Three Kingdoms Clash of Heroes), provided you're on Taiwan-region servers with a verified Taiwan MyCard account.
The window closes hard at April 9 midnight TST. Verification, single-transaction strategy, instant payment, and manual claiming all require deliberate action ahead of time. The players who walk away with maximum diamonds are the ones who plan — not the ones topping up at 11:55 PM on April 9 and hoping for the best.
