Suncoin economy guide

Whoever spends Suncoins better reaches their target board first.

How much sun comes in

confirmed10 suncoins on rounds 1 to 3, 12 on rounds 4 to 6 and 15 from round 7 on (official game table). Unspent sun carries over.

What each ★ costs

officialMerging joins 2 cards of the same ★ (official tip): ★2 = 2 copies, ★3 = 4. Without discounts:

wikiA cost 8 at ★3 is 32 suncoins, almost 3 rounds of income, plus the refreshes to find the copies.

Where sun leaks

• confirmedRefreshing the shop costs 1 suncoin. 5 refreshes a round is almost half your income.
• officialMost Minions only return a small portion of Suncoins based on their ★ rank when sold.
• wikiBuying to sell later is almost always a loss. Buy what fits the plan.
• officialDragging a card in the Shop downward freezes it, keeping it unchanged while the Shop refreshes.
• wikiFreezing is free. Short on sun for a key card? Freeze it and buy it next round instead of refreshing.

Interest: passing without buying

communityPlayer reports: passing the first rounds without buying gives 2 extra suncoins. Headless Jack decks use it because they want to lose HP early. Not confirmed by the site yet.

Cards that play with sun

officialSeed Peon "Reduces the Purchase Price by 2. Temp increases the Purchase Price by 1 for each Seed Peon you buy." The 1st copy costs 1 suncoin; later ones that round cost more.

officialSpudchant "On purchase: Grants 1 free Shop refreshes."

officialCarrot Broker "On purchase: Refreshes the Shop with 1 8-Cost Minions and increases their cost by +2." Guarantees the cost 8, but it costs 10.

officialEggydjinn "Each Suncoin gives Eggydjinns in the Shop ATK +4. Purchase price is equal to currently held Suncoins (no lower than 1)." He takes all your sun and turns it into ATK.

confirmedIf you have sun again next round, you can buy another Eggydjinn.

officialDragon Hoarder "Aura: Increases this Minion's ATK by 4/8/16/48 for every 5 Suncoins you have." Wants the opposite of Eggydjinn: sun kept.

officialJoe Tycoon "Deploy: Increases the selected Minion's ATK by 8 and spends all Suncoins, each increasing its ATK by 2."

The math: Joe Tycoon on Dragon Hoarder

wikiExample: 25 suncoins left after paying for Joe, used on the Dragon. Joe gives +58 permanent ATK (8 + 2 × 25). But sun drops to zero and the Dragon's aura (5 blocks of 5 suncoins) is gone until sun comes back.

wikiNot confirmed: does Joe count coins before or after paying his own price? The table uses the coins left after.

In practice

• wikiEarly: buy what starts your plan and don't refresh for nothing.
• wikiSave sun for ★2 on key cards and for the round before the Boss.
• wikiEggydjinn or Joe: reach the late game with lots of sun. Dragon: never run dry.

The deck builder works out how much sun your target board costs and which round it's ready if you spend everything. See also How the shop works.
