BUILD
Place production, military and defense structures to shape a personal stronghold.
CHAPTER 01 ✦ GAME VISION
What is KINGDOM FLASH?
A colorful fantasy strategy game centered on building and defending a castle, commanding heroes and raiding hostile strongholds. Build powerful walls and towers, position defensive troops and lead real-time castle sieges.
28 × 28City layout tiles
180 SECRaid duration
4 HEROESInitial roster
28 DAYSSeason 01 duration
COMMAND
Recruit specialized troops and deploy up to three heroes as your citadel grows.
CONQUER
Scout defenses, select where to deploy, trigger hero skills and earn siege stars.
DESIGN PRINCIPLE A good layout should defeat a stronger army with smart defenses; a clever army should overcome a higher-level wall by choosing its route and timing.
CHAPTER 02 ✦ PLAYER LOOP
The Gameplay Loop
Players continually expand their castle, strengthen their troops and raid enemy bases. Quests and seasonal goals provide direction without replacing strategy.

SHORT SESSION · 5–10 MIN
Collect resources → queue construction → train troops → attack one AI base → claim a mission reward.
LONG SESSION · 20–40 MIN
Reshape defenses → scout multiple bases → experiment with hero synergies → contribute to a guild objective.
CHAPTER 03 ✦ YOUR CAPITAL
Build a Living Kingdom
Each player owns an editable 28×28-tile city. Construct structures on valid empty terrain, rotate applicable buildings and rearrange walls without losing resources. The Citadel is the strategic center.
How building works
1
Open Build Mode — choose Economy, Military, Defense or Utility.
2
Place on valid tiles — green outlines permit placement, red outlines block overlap and paths.
3
Spend resources — upgrades consume listed resources and assign an available builder.
4
Wait or earn boosts — timers continue while offline; no mandatory paid construction acceleration.
BUILDER CAPACITY Begin with one builder; unlock a second after Citadel Lv. 3 tutorial missions, and a third through Citadel Lv. 7 progression. These builder unlocks are part of the kingdom progression system.
CHAPTER 04 ✦ IN-GAME ECONOMY
Resources & Production
The kingdom economy supports both construction and warfare. Production continues passively up to storage capacity, while raids provide an additional way to gather resources.
| Resource | Produced by | Main uses | Lv. 1 production rate |
|---|---|---|---|
| ● Gold | Gold Mine, battles | Upgrades, hero equipment | 120 / hour |
| ● Wood | Lumber Mill | Walls, towers, construction | 100 / hour |
| ● Stone | Quarry | Citadel, fortress defenses | 75 / hour |
| ● Food | Farm | Training and troop recovery | 140 / hour |
| ◆ Starshards | Quests, events, milestones | Hero awakening, cosmetics | Reward-based only |
STORAGE & PROTECTION
Storage buildings have capacity limits. PvP attacks can seize up to 10% of unprotected stored base resources per raid, with a cap determined by matchmaking tier; Starshards are never lootable.
ANTI-SNOWBALL RULES
New kingdoms receive up to 48 hours of attack protection, ending if they initiate PvP. After a successful enemy raid, grant an 8-hour defense shield to reduce repeated attacks.
CHAPTER 05 ✦ INFRASTRUCTURE
Buildings & Upgrades
Your Citadel level determines building access, hero deployment slots, army capacity and research tiers. Defensive layouts have meaning: walls delay units, towers control lanes and traps punish predictable routes.
| Building | Purpose | First unlock |
|---|---|---|
| ♛ Citadel | Capital core; raises city tier and unlocks features | Lv. 1 |
| ⌂ Farm / Lumber Mill / Mine / Quarry | Generate the four primary resources | Lv. 1–2 |
| ▣ Warehouse | Expand and protect resource storage | Lv. 1 |
| ⚔ Barracks | Train army units and manage training queues | Lv. 1 |
| ✷ Hero Hall | Recruit, level and assign active or defending heroes | Lv. 1 |
| ♜ Walls / Archer Towers | Redirect troops and deal ranged defensive damage | Lv. 2 |
| ⚒ Forge | Craft and improve non-randomized hero equipment | Lv. 3 |
| ✦ Academy | Research economy, army and defense technologies | Lv. 3 |
| ◈ Cannon Tower / Watchtower | Area damage and early warning against raids | Lv. 4–5 |
| ✧ Rune Obelisk | Magical defense; counters clustered enemies | Lv. 6 |
| ⚑ Guild Hall | Guild membership, donations and war support | Lv. 6 |
Citadel Upgrade Requirements
| Upgrade | Upgrade cost | Build time | New feature |
|---|---|---|---|
| 1 → 2 | 1,000 Gold + 400 Wood | 3 min | Walls, Ranger training |
| 2 → 3 | 2,800 Gold + 1,200 Stone | 30 min | Forge, Academy, second builder quest |
| 3 → 4 | 6,500 Gold + 2,800 Stone | 2 hrs | Second active hero, Cannon Tower |

| 6 → 7 | 45,000 Gold + 24,000 Stone | 20 hrs | Third hero, third builder quest |
Citadel progression covers 10 levels at launch, with higher tiers unlocked through economy and defense requirements.
CHAPTER 06 ✦ THE FOUR CHAMPIONS

HERO GROWTH
Gain EXP through PvE and raids. Equipment slots unlock at hero Lv. 3; talent paths at Lv. 5. Hero ascensions require obtainable in-game fragments.
CHAPTER 07 ✦ ARMY STRATEGY
Troops & Formations
Armies are assembled by housing capacity, not just unit count. Players choose troop types and assign a hero leader before an attack.
| Unit | Housing | Role & counter | Unlock |
|---|---|---|---|
| 🛡 Shieldguard | 2 | Tanks damage; protects fragile troops | Citadel 1 |
| ➶ Ranger | 2 | Long range; effective against mages | Citadel 2 |
| ⚑ Lancer | 3 | Anti-cavalry charge; controls chokepoints | Citadel 3 |
| ♞ Rider | 4 | Fast flanking attacks; targets Rangers | Citadel 4 |
| ✧ Arcanist | 4 | Magical damage; breaks armored guards | Citadel 5 |
| ⚒ Siege Golem | 8 | Slow; prioritizes gates, walls and cannons | Citadel 6 |
| ✚ Warden | 5 | Heals allies; vulnerable when isolated | Citadel 7 |
Rangers beat ArcanistsRiders beat RangersLancers beat RidersArcanists beat Shieldguards
Formations
SHIELD WALL
Frontline troops absorb hits; effective versus towers and open lanes.
WEDGE STRIKE
Fast army concentrates on one breach; risky against cannons.
SPLIT SIEGE
Two entry points pressure separate defenses and divide target priority.
Training consumes Food and sometimes Gold. A defeated raid loses deployed troops but never permanently destroys the player's buildings.
CHAPTER 08 ✦ CASTLE SIEGE
Attack & Defense System
Battle style: short, real-time, asynchronous castle raids. The player prepares an army and heroes, scouts an enemy layout, deploys troops along the perimeter and activates hero abilities when the timing is right. Defenses respond automatically.
SCOUT
20 secondsInspect towers, traps, walls, loot and citadel location. Adjust hero and troop mix.
DEPLOY
Up to 180 secondsDrag or tap troops onto allowed border zones. Choose one or several attack lanes.
COMMAND
During the attackUse timed hero abilities and tactical Flash Orders to alter the battle.
RESULT
End of raidStars, loot, trophies, EXP, replays and quest progress are calculated.
Three-star objectives
★50% DESTRUCTIONDestroy at least half the enemy base's buildings.
★★CITADEL FALLSDestroy the enemy Citadel; awards another distinct star.
★★★100% CLEARDestroy all eligible buildings and finish the raid.
Stars are based on these three independent achievements; the total cannot exceed three. A player may win with one or more stars, while zero stars is a defeat.
The signature mechanic: FLASH ORDERS
Each raid has a shared Command Meter (0–100). Destroying enemy military structures charges the meter. Players may issue up to two orders per battle, creating a tactical choice rather than passive auto-combat.
RALLY CRY · 40
Nearby allies gain +25% movement speed for 6 seconds.
AEGIS WARD · 50
Absorbs damage equal to 18% max HP for 6 seconds.
SIEGE PULSE · 60
One area strike deals bonus damage to walls and defensive buildings.
Defensive rules & fair matchmaking
INTELLIGENT GARRISON
Towers prioritize enemies by range, type and threat. A defending hero uses predefined defensive abilities.
LAYOUT SNAPSHOT
Raids attack a stored snapshot of the city. Destruction does not damage the permanent home base.
FAIR MATCHES
Matchmaking first checks Citadel levels within ±1 and army power ratings within 20%, then progressively expands the search range.
RAID PROTECTION
Matchmaking rate limits repeated attacks, caps loot and gives protection after significant defeats.
CHAPTER 09 ✦ WAYS TO PLAY

Citadel 4–6
Build specialized towers, recruit a second hero, research formations and start competitive raids.
Citadel 7–10

Balancing commitments
- Counterplay matters more than raw combat power. Avoid unstoppable hero combinations.
- Core heroes and troops must be earnable by playing, not locked behind purchases.
- Defense losses never erase a player's city. Raid loot has strict caps and protections.
- Boosts may accelerate preparation but should not provide decisive exclusive combat statistics.
- Review win rates by hero, army composition, Citadel tier and opponent power before adjusting balance.
