05. Economy

← Back to index

The game has no premium currency. The economy runs on coins (soft currency), with RV as the main shortcut. Random systems (gacha, spins, chests) are covered separately in 06_Gacha.md.

Currencies & Resources

Faucets (coin sources)

a. Level rewards

Linear per customer, where n = global customer number 1…120 [DATA level_rewards.csv].

Coins per day (3★, without ×2, without VIP):

Total Day 1–25: 43,560 (3★) / 23,280 (1★). With RV ×2 this can approach double.

b. VIP

• 200 + 30 × (day − 2) per VIP (Day 25 = 890).
• ×4 with RV, plus 8–10 emoji × random 10–30 coins.
• 30 VIPs across Day 1–25.

c. Daily Login

• 7 days: 250, 500, 750 … 1,750 (7,000 total per cycle).
• 30-day variant (ThrityDaySign, iOS) with exclusive items on days 1/2/4/5/7/9 (daily_bonus_order).

d. Daily Missions

27 missions, rewards of 50–150 coins. Examples: "Create 3 Spray cases" 120, "Upgrade your floor once" 50, "Play boxes mini game 2 times" 150.

e. Keychain Chest

Random 20–440 coins per tap. Details in 06_Gacha.md.

f. Free coin RV

In the Skin panel and the HUD "Earn Coins" button: 500 + 25 × (day − 1) per view (Day 25 = 1,100) [DATA skin_rv_coins.csv].

g. Idle Income

[CODE ✔]

coins = hours × (worker_count × 50 + shop_income) × (DoubleTime ? 2 : 1)

• Offline savings are capped at 5 hours of worker income (15 hours with the Stretch the Limit booster).
• Workers are obtained through RV and are temporary.

Permanent boosters are sold as IAP. Booster durations could not be read from the code.

h. Spin Wheel

Rewards of 100–2,000 coins. Details in 06_Gacha.md.

i. Auction

Bids of 1.0–3.0 × the 3★ reward. Details in 03_Customers.md.

j. Extra Coins RV

RV coin buttons in the HUD, shop and floating icons (extra_coins_rv, float_skin_rv, MysteryBoxRV).

Sinks (coin spending)

a. Studio (shop decor)

10 categories, 125 items [DATA Decorations_Categories.csv, Decorations_Items.csv].

• Breakdown: 35 free (default), 57 coin-priced, 33 RV-only (1 ad per item).
• Coin prices range 50 → 1,500. All coin items total 33,400, about 77% of total 3★ income for Day 1–25. The sink is tuned so the studio is "almost full" around Day 25.
• Price pattern per category: 2–5 free items → coin items rising gradually → RV items interleaved between coin items (by order). Players short on coins see RV as the shortcut.
• Studio upgrades (interior/wall/floor) also give +80 leaderboard points.

b. Tool Skins (gacha roll)

49,500 coins in total for all skins. Details in 06_Gacha.md.

c. Bundle timer skip

500–1,000 coins per cycle. Details in 08_LiveOps_AB.md.

Rough balance, Day 1–25

Total sinks are well above the level faucet. This shortfall is what pushes players to watch RVs. [GUESS]
