Clash of Clans is a midcore mobile strategy game developed by Supercell. The core gameplay revolves around base building, resource management, and multiplayer attacks. Players construct and upgrade their village, train troops, and attack other players to earn resources that fuel further progression.

A key design characteristic is its time-gated progression system, where upgrades often require hours or days to complete. This creates natural progression friction, which becomes the foundation of its monetisation strategy.

Importantly, Clash of Clans does not rely on third-party advertisements for monetisation. Instead, it uses progression-based monetisation systems integrated directly into gameplay, ensuring immersion is never broken by external ads.

Clash of Clans uses a seasonal progression system called the Gold Pass, which provides additional rewards over time. A key design strategy is the central importance of Heroes.

Heroes are presented as powerful, persistent characters that players invest heavily in upgrading. Over time, Heroes become the player's primary strategic assets and emotional anchors. Once players develop this attachment, Supercell introduces monetised content related to these heroes — hero skins, faster hero progression, and exclusive seasonal rewards.

This leverages a well-known psychological principle: players are more likely to invest in systems they emotionally identify with.

Even players who do not purchase the seasonal pass continue to receive limited rewards, ensuring continued engagement and maintaining progression momentum. However, the paid pass offers significantly improved progression speed and exclusive cosmetic rewards, increasing its perceived value.

Builders are required to construct and upgrade buildings. Players start with a limited number of builders, which directly restricts how many upgrades can occur simultaneously. This creates progression bottlenecks.

Players have three options: wait for builders to become available, optimise upgrade strategy, or purchase additional builders using Gems. Gems are the premium currency and are intentionally difficult to accumulate in large quantities through normal gameplay.

However, Clash of Clans frequently offers discounted Gem packs and limited-time offers with visible discounts, limited-time availability, and bonus value perception — creating urgency and increasing purchase likelihood.

Clash of Clans frequently presents limited-time offers and discounted bundles. This strategy leverages urgency-based decision-making, where players perceive temporary offers as opportunities they should not miss.

A comparable example is Udemy, where courses are frequently discounted with visible time limits, significantly increasing conversion rates. Clash of Clans applies the same psychological principle within its in-game economy.

This system monetises player impatience and FOMO rather than forcing purchases — players feel they are getting a deal, not being pressured.

The introduction of UPI in India has significantly reduced payment friction. Previously, purchases required credit cards and multi-step payment processes. Now, purchases can be completed instantly, reducing the time between purchase intent and purchase completion — directly increasing impulse purchasing behaviour.

According to the Lumikai State of India Gaming Report, 148 million users make in-game purchases, with millions of new paying players added annually. In-app purchases, propelled by mid-core games, grew significantly year-on-year — confirming that midcore games like Clash of Clans are a major driver of mobile gaming revenue growth.
