Sportlens found that the world's five top-grossing mobile games raked in a whopping $US 7.2 billion last year, or $AUD 10.3 billion. This is $US 400 million - or $AUD 570.4 million more than in 2021.

Further, two games stood out well beyond the rest, both from Tencent: Honor of Kings and PUBG Mobile. These both gross higher revenues than any other mobile game. In fact, combined, they brought in almost $US 4 billion for Tencent, which is more than the next highest revenue games - Genshin Impact, Candy Crush Saga, and Roblox - combined.

Honor of Kings brought in a huge $US 2.2 billion in revenue in 2022, while PUBG Mobile earned Tencent a tidy $US 1.72b.

Candy Crush Saga drew $US 1.03 billion from its fan base on in-app purchases.

Yet, the number of people playing mobile games actually plunged by 104 million, or 5.7%, in 2022. Nevertheless, Sportslens is expecting this to change, seeing 1.86 billion mobile gamers in 2023, and over 2 billion mobile gamers by 2025 - and with that growth, no doubt too, so will the amount of mobile game in-app purchase spending increase too.
