2019 was another stellar year for mobile game revenue. Sensor Tower estimates show that worldwide spending in games grew 12.8% across the App Store and Google Play, from $54.7 billion in 2018 to $61.7 billion in 2019. For some perspective, that's 74% of all in-app spending for the year, which hit approximately $83.5 billion in total not including Android in China.
Tencent's Honor of Kings was once again the highest-grossing game of the year, generating close to $1.5 billion in gross revenue. Another title from the Chinese publishing giant, PUBG Mobile, shot up the charts in 2019 to hit No. 2 in the rankings with just under $1.5 billion as well. The battle royale game grossed close to $1.3 billion more than in 2018 thanks to its re-launch in China, where it's now known as Game For Peace.
The top five was rounded out by Sony Aniplex's Fate/Grand Order -- which became Japan's top grossing game of 2019, usurping Mixi's Monster Strike - King's Candy Crush Saga, which increased user spending by $84.5 million year-over-year, and Niantic's Pokémon GO, which had its best year ever.
