Lucky Discounter

Event guide, probability breakdown & draw tracker

How It Works

  1. Use Coupons (refresh tickets) to draw for a random discount. Each draw costs 1 ticket — your 1st draw is free.
  2. Drawing activates an exclusive time-limited shop. Items are sold at the drawn discount price until the timer expires.
  3. Every new draw re-activates the shop and refreshes the available items with a new discount.
  4. Tickets carry over between event cycles and do not expire. You earn roughly 4–5 tickets per event cycle.
  5. After the event ends, ranking rewards are sent via in-game mail.

Guaranteed Drops & Pity System

Guaranteed 90% Off

You are guaranteed a 90% Off discount on these specific draw numbers:

5th 9th 18th 32nd

Pity Counter

Every 25 cumulative draws without a 90% Off guarantees one.

The pity counter resets each time you receive a 90% Off — whether from a guaranteed drop or the pity system.

What to Buy at 90% Off

When you hit 90% Off, buy everything you can. Here’s the priority:

1
Badges

2,000 badges for ~600 diamonds = 0.3 diamonds/badge. Normal price is ~1.5 diamonds/badge — that’s 5x better value. This is one of the best badge sources in the game.

2
Speedups

Building and research speedups at 90% Off are excellent value. Stock up for upgrade days.

3
Everything Else

At 90% Off, almost anything is worth buying. Grab whatever you need most.

Strategy Tips

  • Save at least 9 tickets before starting — this guarantees you hit the 5th and 9th draw thresholds for two 90% Off discounts.
  • For maximum value, aim for 18 or 32 tickets to hit the later guaranteed drops (requires saving over multiple event cycles).
  • The pity counter means you’ll never go more than 25 draws without a 90% Off after your last one.
  • Have diamonds ready before the event — don’t waste a 90% Off draw without enough diamonds to buy the best items.
  • Buy immediately when you hit 90% Off — the shop timer is limited and items refresh on the next draw.
  • Lower discounts (10–30%) can still be useful for cheap consumables you need in bulk, but the real value is at 90%.
  • Since tickets carry over, there’s no rush. It’s better to save for guaranteed drops than spend randomly.
