# Iridium
|
|
|
|
## 매 한 줄
|
|
> **"매 Iridium은 War Commander 계열의 hard premium currency"**. 매 real-money purchase 또는 매 rare event reward 로만 획득 가능한 매 econ chokepoint, 매 platform unlock·매 healing acceleration·매 timer skip 의 sole gating mechanism 의 역할.
|
|
|
|
## 매 핵심
|
|
|
|
### 매 Source vs Sink
|
|
- **Source**: 매 IAP bundle (USD → Iridium pack), 매 daily login streak (소량), 매 limited event leaderboard top reward, 매 War Commander Black Friday promo.
|
|
- **Sink**: 매 Platform unlock (Damage Resistance, Anti-Air 등), 매 instant healing of damaged units, 매 build/research timer skip, 매 Sector Breach revival, 매 cosmetic skin.
|
|
|
|
### 매 Whale-targeted Design
|
|
- 매 Iridium pack 의 매 tiered pricing: $4.99 / $19.99 / $99.99 / $499.99.
|
|
- 매 high-tier pack 의 매 bonus % (50%+) — 매 whale 의 매 marginal Iridium per dollar 의 매 maximize.
|
|
- 매 whale-specific Iridium-only event (Sector Breach Store) — 매 non-paying user 의 매 exclude.
|
|
|
|
### 매 응용
|
|
1. War Commander (Kixeye, 2011) — 매 origin of the Iridium model.
|
|
2. Mobile Strike — 매 Gold (analogue currency) 의 매 same role.
|
|
3. Boom Beach (Supercell) — 매 Diamond (similar premium hard-currency).
|
|
|
|
## 💻 패턴
|
|
|
|
### Iridium balance tracking (server-authoritative)
|
|
```typescript
|
|
// Server-authoritative wallet — never trust client
|
|
interface IridiumWallet {
|
|
userId: string;
|
|
balance: number;
|
|
lifetimeEarned: number; // for whale-tier classification
|
|
lifetimePurchased: number; // for VIP scoring
|
|
lastTxn: Date;
|
|
}
|
|
|
|
async function spendIridium(userId: string, amount: number, sink: SinkType): Promise<TxnResult> {
|
|
return await db.transaction(async (tx) => {
|
|
const w = await tx.wallet.findOne({ userId, lock: 'FOR UPDATE' });
|
|
if (w.balance < amount) return { ok: false, reason: 'INSUFFICIENT' };
|
|
await tx.wallet.update({ userId }, { $inc: { balance: -amount } });
|
|
await tx.iridiumLedger.insert({ userId, delta: -amount, sink, ts: new Date() });
|
|
return { ok: true, newBalance: w.balance - amount };
|
|
});
|
|
}
|
|
```
|
|
|
|
### Tiered IAP bonus calculation
|
|
```python
|
|
# Iridium pack bonus scaling (Kixeye-style)
|
|
PACKS = [
|
|
{"usd": 4.99, "base": 500, "bonus_pct": 0},
|
|
{"usd": 19.99, "base": 2200, "bonus_pct": 10},
|
|
{"usd": 49.99, "base": 6000, "bonus_pct": 20},
|
|
{"usd": 99.99, "base": 13000, "bonus_pct": 30},
|
|
{"usd": 499.99,"base": 75000, "bonus_pct": 50}, # whale tier
|
|
]
|
|
|
|
def total_iridium(pack):
|
|
return int(pack["base"] * (1 + pack["bonus_pct"] / 100))
|
|
|
|
# whale gets 112,500 Iridium for $499.99 — vs 50,000 if linear
|
|
```
|
|
|
|
### Skip-timer pricing curve
|
|
```typescript
|
|
// Iridium cost to instant-finish a build/research timer
|
|
function skipCost(remainingSec: number): number {
|
|
// Kixeye uses ~1 Iridium per minute remaining, with floor and ceiling
|
|
const minutes = Math.ceil(remainingSec / 60);
|
|
const cost = Math.max(1, Math.min(2000, Math.ceil(minutes * 0.95)));
|
|
return cost;
|
|
}
|
|
// 24h timer remaining → 1368 Iridium (~$5-10 worth depending on pack)
|
|
```
|
|
|
|
### Sector Breach revive gate
|
|
```typescript
|
|
// Critical sink — only Iridium can revive in PvP Sector Breach
|
|
async function revivePlayer(userId: string, sectorId: string) {
|
|
const reviveCost = 250 + getDeathCount(userId, sectorId) * 100; // escalating
|
|
const result = await spendIridium(userId, reviveCost, 'SECTOR_REVIVE');
|
|
if (!result.ok) return { revived: false };
|
|
await respawnUnit(userId, sectorId);
|
|
return { revived: true, cost: reviveCost };
|
|
}
|
|
```
|
|
|
|
### Whale-tier unlock detection
|
|
```typescript
|
|
// Trigger VIP customer-success outreach when lifetime Iridium spend crosses threshold
|
|
const WHALE_TIERS = { silver: 10_000, gold: 50_000, diamond: 250_000 };
|
|
|
|
function classifyWhale(lifetimePurchased: number): keyof typeof WHALE_TIERS | 'none' {
|
|
if (lifetimePurchased >= WHALE_TIERS.diamond) return 'diamond';
|
|
if (lifetimePurchased >= WHALE_TIERS.gold) return 'gold';
|
|
if (lifetimePurchased >= WHALE_TIERS.silver) return 'silver';
|
|
return 'none';
|
|
}
|
|
```
|
|
|
|
### Iridium event leaderboard reward distribution
|
|
```python
|
|
# Top-N players in event leaderboard get Iridium scaled by rank
|
|
def event_iridium_reward(rank: int) -> int:
|
|
if rank == 1: return 5000
|
|
if rank <= 10: return 2000
|
|
if rank <= 100: return 500
|
|
if rank <= 1000: return 100
|
|
return 0 # cliff — only top performers get hard currency
|
|
```
|
|
|
|
## 매 결정 기준
|
|
| 상황 | Approach |
|
|
|---|---|
|
|
| F2P war/strategy game 의 hard currency 도입 | 매 Iridium-style single-currency model 권장 |
|
|
| Platform/feature gating 의 magnitude 결정 | 매 60-90% paywall (free 못 unlock 일부 platform) |
|
|
| Skip timer 의 pricing | 매 1 Iridium ≈ 1 min, ceiling at 2000 |
|
|
| Whale outreach trigger | 매 lifetime $500+ spend |
|
|
|
|
**기본값**: 매 single hard currency (Iridium) + 매 dual soft currency (Metal/Oil) — 매 War Commander canonical pattern.

|
## 🤖 LLM 활용
|
|
**언제**: 매 mid-core strategy game 의 hard-currency design, 매 War Commander-style econ analysis, 매 whale-tier IAP modeling.
|
|
**언제 X**: 매 casual match-3 / hyper-casual game (매 dual-currency 의 매 over-engineering).
|
|
|
|
## ❌ 안티패턴
|
|
- **Skip-timer over-pricing**: 매 cost > 매 1.5 USD/hour 의 매 churn 의 매 spike.
|
|
- **Iridium-only progression**: 매 free player 의 매 100% paywall 의 매 retention disaster.
|
|
- **Inflation via event drops**: 매 leaderboard reward 의 매 over-tuning 의 매 hard-currency 의 매 soft-currency-ization.
