What Is the Spring 2026 Promotion?
A tiered top-up bonus event where single-transaction size determines your bonus percentage. Larger single transactions unlock higher tiers — that's the foundational mechanic everything else builds on.
Confirmed bonus tiers:
| Single Top-Up Amount | Bonus % | Effective Diamonds |
|---|---|---|
| TWD 3000 | 30% | 4,500–6,500 (game-dependent) |
| TWD 1000 | 20–25% | 1,400–2,000 |
| TWD 300 | 15% | 400–600 |
| TWD 30 / TWD 90 | 10% | Minimal — skip these |
Eligible games: MLBB TW, Tower of Saviors (ToS), Night Crows, Three Kingdoms Clash of Heroes, Lineage W. If your game isn't on this list, spring bonuses don't apply.
What makes this campaign different: the single-transaction requirement. Each transaction is evaluated independently. Splitting a TWD 3000 purchase into three TWD 1000 transactions is one of the most expensive mistakes you can make — you lose up to 500 diamonds.
Key dates:
- Campaign opens: February 9, 2026
- ToS sub-event participation closes: March 15, 2026
- ToS reward claims deadline: April 9, 2026
- All Spring 2026 bonuses expire: April 9, 2026, midnight TST
Set a personal deadline of April 7 for ToS claims. The final 48 hours carry real risk of processing delays.
Two Bonus Systems Running Simultaneously
Most guides miss this. MyCard platform bonuses and in-game top-up bonuses are separate systems that stack.
The platform-level bonus is what MyCard awards at redemption — the 15–30% extra diamonds credited as a separate line item in your game dashboard, triggered by denomination and timing at mycard520.com.tw.
The game-side bonus is whatever the individual game runs independently — MLBB's Task Master event (Feb 13–26), ToS's point accumulation pool (Feb 16–Mar 15), Night Crows' seasonal currency multipliers. These stack on top because they operate at different transaction layers.
Eligibility requirements:
- MyCard member account linked to Taiwan region
- KYC identity verification completed before TWD 3000 tier transactions
- 2FA and 6-digit password configured — do this early, not April 8
- Active VPN or non-TW server account blocks bonus eligibility entirely
Once bonus diamonds land in your game account, they carry no separate expiry. They're treated as standard in-game currency — permanently yours once credited.
Which Denomination Actually Wins
TWD 3000 is the clear winner for anyone who can commit to it. Thirty percent bonus, no splitting, best ratio available. Community consensus and official mechanics both confirm this.
TWD 1000 is right for smaller budgets. At 20–25% bonus, it's a solid middle tier. Two TWD 1000 transactions yield two separate bonuses — which actually beats one TWD 2000 transaction that only qualifies for the lower tier anyway.
TWD 300 at 15% works for casual players. Not optimal, but not negligible.
TWD 30 and TWD 90 at 10% — skip during the spring event. The bonus is too thin, and you're better off saving toward a higher tier.
One important caveat: if you're forcing a TWD 3000 purchase purely to hit the bonus tier but don't actually need that much currency right now, you're not saving — you're overspending. The 30% bonus only wins if you were going to spend that amount anyway.
Digital vs. physical cards: Community testing confirms digital PIN codes from platforms like BitTopup qualify fully for Spring 2026 bonuses. No eligibility difference from physical cards. Digital wins on speed and cost — physical retail cards don't carry the ~40% discount that digital sourcing enables.
The Four-Layer Stacking Framework
Individual deals are easy to find. The sequencing of multiple simultaneous layers is where real savings live.
Layer 1 — MyCard Platform Spring Bonus
The foundation. Redeem your PIN at mycard520.com.tw during Feb 9–Apr 9, select your eligible TW game account, and the 15–30% bonus diamonds are credited automatically. No opt-in required beyond having a verified TW-region account.
Layer 2 — In-Game Event Bonuses
Time your redemption to overlap with active in-game events:
- MLBB Task Master: February 13–26 — diamonds feed directly into event progress
- ToS point accumulation pool: February 16–March 15 — 3,750 points unlocks 5 redemptions (6D, 800 Souls, 8M Coins, 1 Harpy), claimable until April 9
- Night Crows and Lineage W seasonal events run concurrently — check their official event pages for exact windows
Your platform bonus diamonds and in-game event rewards are both active simultaneously. You're not choosing between them.
Layer 3 — Payment Method Cashback
Significant for Taiwan-based buyers. TW credit cards and telecom providers (Taiwan Mobile, for example) offer up to 7% cashback on MyCard purchases through official channels. E-wallet cashback runs 2–3% and also stacks.
Note: this cashback layer applies to purchases on the official MyCard platform. If you're buying through BitTopup, that specific cashback may not apply — but the ~40% platform discount more than compensates. For international players without TW banking access, BitTopup is the practical path to buy MyCard (TW) cheap price without needing a local SIM or bank account.
Layer 4 — Free Codes and Sub-Event Rewards
Three official MLBB redemption codes — 2y3vo2r3x, 0nc9lhok9, and 3r83efok9 — were available February 9 for a combined 112 diamonds (~37–38 each). These expired by early March, but the pattern holds: launch-day free codes are a real value layer requiring zero spend.
For ToS players: sub-event rewards don't auto-apply. If you accumulated points during Feb 16–Mar 15, manually claim your rewards before April 9. Set a calendar reminder for April 7.
Before purchasing, verify all four layers:
- MyCard account verified and TW-region linked
- Official MyCard event page shows active spring bonus tiers
- In-game event confirmed live
- Payment method cashback program covers the transaction type
When to Pull the Trigger
"Buy during the event" isn't a strategy. Here's the actual timing breakdown.
Early event (Feb 9–Feb 15): Best for free code redemptions and launch-day bonuses. MLBB Task Master starts Feb 13 — a TWD 3000 redemption on Feb 13–14 hits both the platform bonus and event entry simultaneously.
Mid-event (Feb 16–Mar 15): The ToS accumulation pool is live, MLBB Task Master is running, maximum flexibility. This is the optimal window for most players — all game-side events are active, no deadline pressure.
Final days (Apr 7–Apr 9): Avoid the last 24 hours if possible. Bank transfer processing near the cutoff risks missing the window. If you must top up in the final 48 hours, use e-wallet or FPX for faster settlement. Hard personal deadline: April 7.
Game-Specific Playbooks
MLBB TW: Redeem your TWD 3000 PIN on Feb 13 to immediately feed diamonds into Task Master progress while capturing the 30% platform bonus. The Weekly Diamond Pass also stacks — pass diamonds and bonus diamonds both count toward event thresholds.
Tower of Saviors: Sub-event closed March 15 for new participation, but reward claims run until April 9. If you're in the pool with 3,750 points, claim your 5 redemptions before the cutoff. Platform bonus still applies through April 9 for new top-ups — just without the accumulation layer.
Night Crows, Lineage W, Three Kingdoms Clash of Heroes: All confirmed eligible. Check each game's official event calendar for seasonal multipliers overlapping Feb 9–Apr 9. The stacking principle is identical — time your TWD 3000 redemption to an active in-game event.
How to Buy via BitTopup and Apply to Spring Promotions
Community testing confirms digital PINs from BitTopup carry full Spring 2026 bonus eligibility.
- Complete MyCard KYC first. Log into your MyCard member account and finish identity verification, 2FA setup, and 6-digit password configuration. Mandatory for TWD 3000 tier. Do it now.
- Purchase your PIN on BitTopup. Select TWD 500 or above. Pay, receive serial number and password by email — typically instant delivery.
- Redeem at mycard520.com.tw. Go to Payment Center, enter your PIN, select your TW game account. Confirm TW region server — wrong server means no bonus.
- Verify bonus activation. Check your game dashboard for bonus diamonds as a separate line item. If absent after a few minutes, check MyCard Member Center transaction history.
The math on a TWD 3000 transaction via BitTopup: effective cost USD 100.46 (USD 3.35 per 100 TWD), plus 30% bonus diamonds on top. Both levers move in your favor simultaneously — you paid less and received more. That's the full stacking picture.
For players outside Taiwan who want the MyCard (TW) best deal online without a local bank account or TW SIM, this is the practical path.
Mistakes That Kill Your Savings
Splitting large top-ups. A TWD 3000 split into ten TWD 300 transactions gives you 15% ten times instead of 30% once. You lose up to 500 diamonds. Single transaction, always.
Wrong region or wrong server. MyCard account must be TW-region linked. Game account must be on TW servers. VPN masking your region blocks eligibility entirely — no retroactive credit.
Skipping KYC until the last day. Verification queues spike near April 9. Players who wait until April 7–8 report delays that push them past the cutoff.
Missing the ToS manual claim. Rewards don't auto-apply. If you participated in Feb 16–Mar 15 accumulation, manually claim before April 9.
Redeeming after April 9. The redemption date determines eligibility, not the purchase date. A PIN bought April 8 but redeemed April 10 gets no spring bonus. The base value isn't lost — but the 30% is gone permanently.
Active VPN during redemption. Community reports confirm VPN connections trigger region mismatch errors at mycard520.com.tw. Disable before redeeming.
Budget Scenarios
| Monthly Budget | Recommended Approach | Effective Bonus | Notes |
|---|---|---|---|
| TWD 3000 | Single TWD 3000 transaction | 30% (~900–1,950 bonus diamonds) | Best ratio; KYC required |
| TWD 1000 | Single TWD 1000 transaction | 20–25% (~280–500 bonus diamonds) | Good budget option; don't split |
| TWD 300 | Single TWD 300 transaction | 15% (~60–90 bonus diamonds) | Casual tier; acceptable |
FAQ
Do spring bonus diamonds count toward in-game event thresholds? Yes. Once credited, bonus diamonds are indistinguishable from purchased diamonds — they count toward MLBB Task Master progress, ToS accumulation pools, and any threshold tracking total diamonds received.
Can I redeem multiple PINs in one session? Yes, but each PIN is evaluated independently. A TWD 1000 PIN and a TWD 2000 PIN don't combine into a TWD 3000 transaction — each qualifies for its own tier separately.
I bought a PIN before April 9 but redeemed after. Do I get the bonus? No. Redemption date determines eligibility. Redeem before midnight TST April 9 — no exceptions.
Is there a per-account purchase cap? No per-day cap has been officially confirmed. KYC verification for TWD 3000 tier transactions functions as a practical identity-based limit. Always check official MyCard event terms for updates.
Why isn't my bonus showing up after redemption? Most common causes: wrong game server, unverified MyCard account, active VPN during redemption, or ineligible game title. Check MyCard Member Center transaction history first — if the redemption registered, bonus diamonds should appear within minutes.
Does the BitTopup discount stack with the official spring bonus? Yes, confirmed by community consensus. The BitTopup discount reduces your purchase cost at the point of buying. The MyCard spring bonus adds diamonds at the point of redemption. Independent systems — both apply simultaneously.
The Spring 2026 window closes April 9 at midnight TST. If you're playing any of the five eligible games and haven't locked in your TWD 3000 redemption, the mid-event window is still your best opportunity — all game events active, verification queues manageable, full stacking framework available. Don't leave 30% of your diamonds on the table.
