The Clash of Clans system
A base-building game where Town Hall level is the gate to every other mechanic in the game.
The design logic
Clash of Clans is organized around build timers. Resources are spent on buildings, upgrades take real-world time, and the player attacks other villages to earn more resources while waiting. Town Hall upgrades gate every downstream mechanic: new buildings, new content, the season pass, and even participation in the ranked league system. The Builder Base is a fully separate village with its own currencies, troops, and progression track.
The mechanic sequence
Spend gold and elixir on buildings and upgrades. Attack goblin camps or other players to earn more resources while timers run. Complete challenges for milestone rewards that feed back into construction. Upgrade the Town Hall to unlock new buildings and game modes. Join a clan for troop donations and war participation. Earn league medals through clan war leagues. Spend league medals in the League Shop.
The system map
Tap any + on a connection to see how the two mechanics interactCooperative groups with war participation, troop donations, and clan XP. The achievement system explicitly rewards clan participation, creating a loop from solo progression into social engagement.
Starter Challenges are the primary progression guidance system, organized by point values with milestone rewards. New challenges unlock per Town Hall level.
Player level (separate from Town Hall level) advances through XP earned from achievements and battles. The Supercell ID achievement pays 10x more XP than standard achievements.
Organized by village and category. The Supercell ID achievement awards 100 XP and 50 gems vs. 10 XP and 5 gems for standard tasks, making account linking the single highest-rewarded action in the system.
Clan War Leagues (8-day cadence), Raid Weekend (weekly), and seasonal scenery events run simultaneously. The season pass unlocks only at Town Hall 7.
The season pass not appearing until Town Hall 7 means a new player can spend many hours in the game before the primary recurring monetization surface becomes available. This is a deliberate sequencing decision: establish the construction loop, the clan loop, and the challenge loop before introducing the pass. By Town Hall 7, the player already has a clan, an ongoing war, and a challenge track to accelerate with the pass.
The suggested upgrade system never leaves the player without a visible next action
The suggested upgrade system never leaves the player without a visible next action. As one upgrade completes, a new one appears. Combined with build timers that create known return windows and challenge rewards that fund the next construction task, the player is always in the middle of something rather than at a stopping point.
