Black Market
The Black Market unlocks at Troop Lv 15, but it only appears to players with good luck (or it will be present all the time at VIP7 and above).
The Black Market is another way for players to get good deals on items. Each time it will have 8 different items for sale which can be purchased with diamonds or gold.
The Black Market will refresh once every 24hrs. You can also use diamonds to refresh it, but it becomes more expensive the more times you do so. With each refresh, the price is 10/20/20/50/50/100 diamonds…
If your VIP level is lower than 7, then there’s a chance the Black Market will appear when fighting or sweeping a stage, and if it does appear there will be a pop-up to notify you. Don’t miss out on this pleasant surprise!
