Shop

The Shop is the core of the economy in Chess Evolved Online.

You may buy packs with random pieces from the shop for dragon coins or rubies. Currently, there are 6 packs available. The bonus drop for each unit comes after the other ones.

Lucky Boxes[]

Boxes can count as lucky if their total point value, based on the combined rarity of the units received, exceeds a certain amount (based on the pack opened), the pack will play a "Lucky" sound upon opening.

Rarity	Points
Common	0
Rare	1
Epic	5
Legendary	15

Exchange[]

Exchange screen gives players the ability to exchange currencies for other currencies.

Currency Exchange[]

Currency exchange allows players to buy rubies for coins and vice versa. Players can buy coins for 5, or buy 5 rubies for . Exchange rates depend on past exchanges made by other players, as buying coins reduces Market Value by 1 and buying rubies increases Market Value by 1.

Each exchange has a total of 500 gold tax, as both buying and selling effectively costs 250 gold.

Buying Coins: -5, +5MV - 250

Buying Rubies: +5, -5MV - 250

Global Token Trade[]

It isn't clear yet whether this shop will ever be implemented, so it's only visible as [LOCKED PROTOTYPE]. It's supposed to let players buy and sell tokens unlocking special game modes.

Blitz Token
Flame Token
Hell Token

Global Crystal Trade[]

Apparently, crystals are supposed to be a special resource used to improve pieces in place of upgrading them.

Unit Shop[]

It is possible to buy individual units from the shop directly for rubies or sell them for coins. The price of each unit is inversely proportional to its amount in stock, reaching maximum when there are no pieces available. Thus, high price and stock shortage may be a good sign that certain piece is better than others. Unlocking each tier requires a certain amount of Experience or Rating.

Rarity	Experience	Rating	Min Price	Max Price	Max Stock
Common	10,000	250	1	4	10,000
Rare	15,000	500	3	10	2,500
Epic	20,000	750	20	50	500
Legendary	25,000	1,000	50	175	100

As of 0.43, the market does not regenerate. The only way to restock the shop is to sell pieces.

Pieces sold into a shop that is already at maximum stock are destroyed permanently.

New pieces introduced in an update are automatically fully stocked.

Blessings[]

Blessings give extra gold after each Practice and Ranked match.

Type	Requirement	Value	Effect
Dragon's Favor	500	1	+50%
Dragon's Grace	1500	3	+100%
Dragon's Blessing	2500	6	+150%

Note that blessings multiply the Blitz coin bonus as well.

Buying Rubies[]

Ruby buy screen (kongregate) — Kongreagte Buy Ruby menu.

Rubies can be bought for Kreds on Kongregate or directly on Facebook. The menus shown are different for each; a Phoenix can be seen to the right, and on Facebook there are amounts behind the Kreds symbol. A one-time bonus for 50 contribution is given for the first purchase.
