In the ever-evolving world of mobile gaming, the trend towards 'free' games is on the rise. The primary reason is the shift from upfront cost to in-app purchases; developers are making their money through microtransactions within the game. This strategy lures more users in and gives them a taste of the game before they decide to spend. Advertising revenue also plays a significant role in this new business model. So while the games may be 'free' to download, the industry is finding new, interactive ways to monetize their products.
