What is Lucky Discounter?
Lucky Discounter is a recurring event where you can purchase items at random discounts. The key is that certain attempts guarantee 90% off, making this the best event for farming badges.
Why badges matter: Badges are required for Alliance Recognition research, which unlocks medal production, hero training speed, and other critical bonuses. You need tens of thousands of badges to complete this research tree.
Schedule / When Is Lucky Discounter?
Lucky Discounter follows a consistent weekly rotation: Gacha Go → Bullseye → Lucky Discounter → Lucky Chest. Plan tickets and diamonds around this cycle so you can hit the guaranteed 90% attempts when Lucky Discounter returns.
Guaranteed 90% Discount Attempts
These attempts ALWAYS give 90% off — no luck involved:
| Attempt | Discount | Tickets Needed |
|---|---|---|
| 5th | 90% guaranteed | 4 tickets + 1 free |
| 9th | 90% guaranteed | 8 tickets + 1 free |
| 18th | 90% guaranteed | 17 tickets + 1 free |
| 32nd | 90% guaranteed | 31 tickets + 1 free |
Strategy: Save tickets until you have enough to reach at least the 9th attempt (two guaranteed 90% discounts).
What to Buy at Each Discount Level
| Discount | Badges | Speedups | Other Items |
|---|---|---|---|
| 90% | BUY ALL | BUY ALL | BUY ALL |
| 70% | BUY | BUY (if needed) | Consider |
| 50% | BUY (if rich) | SKIP | SKIP |
| 30% | SKIP | SKIP | SKIP |
| 10% | SKIP | SKIP | SKIP |
Key rule: Never buy speedups below 90% discount — VIP shop prices are similar or better. Badges can be bought at 50%+ if you have excess diamonds. For another diamond event, check out Gacha Go for Golden Wrenches.
Price Comparison: Lucky Discounter vs VIP Shop
Badges
- VIP Shop: 100 badges for 150 diamonds = 1.5 diamonds/badge
- Lucky Discounter 90%: 2,000 badges for 600 diamonds = 0.3 diamonds/badge
- Savings: 5x better value at 90% discount
Speedups
- VIP Shop: ~32 hours for 1,700 diamonds
- Lucky Discounter 50%: 15 hours for 900 diamonds (similar to VIP)
- Lucky Discounter 90%: 25 hours for 900 diamonds (much better)
Conclusion: Only speedups at 90% beat VIP shop. Badges are always better in Lucky Discounter at 50%+.
Ticket Saving Strategy
Refresh tickets accumulate between events. The optimal approach:
Minimum Viable (9 tickets)
- Guarantees two 90% discounts (5th and 9th)
- Good for F2P with limited patience
- Accumulates in ~2 months
Recommended (18 tickets)
- Guarantees three 90% discounts (5th, 9th, 18th)
- Best balance of waiting vs rewards
- Accumulates in ~4-5 months
Maximum Value (32 tickets)
- Guarantees four 90% discounts (5th, 9th, 18th, 32nd)
- Requires ~8 months of saving
- Best for patient endgame players
Tip: You get roughly 4-5 tickets per event cycle. Save them until you hit your target number.
Real Spending Results
Actual results from spending with 32 tickets:
- Diamonds spent: 30,700
- Badges obtained: 42,000
- Building speedups: ~210 hours
- Research speedups: Large amount
- Cost per badge: ~0.73 diamonds
Compare to VIP shop: 42,000 badges would cost 63,000 diamonds (1.5 per badge). Lucky Discounter saved over 32,000 diamonds.
Step-by-Step Strategy
1. Accumulate Tickets
Don't use refresh tickets when you get them. Save until you have at least 9 (ideally 18 or 32).
2. Prepare Diamonds
Before the event, collect diamonds from all sources. You'll need 30,000-80,000 based on ticket count.
3. Use Free Attempt First
Always start with the free attempt. Check the discount before deciding to buy.
4. Skip Low Discounts
If you get 10% or 30%, just refresh and move on. Don't waste diamonds on poor rates.
5. Buy Everything at 90%
When you hit guaranteed 90% attempts (5th, 9th, 18th, 32nd), buy ALL badges and speedups available.
6. Buy Badges at 70%
70% is still excellent value for badges. Purchase badges but skip speedups at this rate.
7. Optional: 50% Badges
If you have excess diamonds and need badges urgently, 50% is acceptable. Never buy speedups at 50%.
Common Mistakes to Avoid
- Buying speedups at 50% or less: VIP shop is the same price or cheaper
- Using tickets immediately: Save them for bulk purchasing
- Buying at 10-30% discount: Terrible value, always skip
- Not preparing diamonds: You need diamonds ready when 90% hits
- Ignoring the event: This is THE best source of cheap badges
Why Focus on Badges?
Badges fuel Alliance Recognition research, which provides:
- Medal production (for hero upgrades)
- Hero training speed bonuses
- Alliance buffs and bonuses
- Critical late-game power multipliers
You'll need 50,000-100,000+ badges to complete Alliance Recognition research. Lucky Discounter is the fastest F2P path to accumulating them. Use badges strategically during Alliance Duel Day 3 for maximum value.
