Candy Crush Saga
Cost:
Free with ads, plus a heavy focus on optional in-app purchases
You probably don’t need an introduction to Candy Crush Saga at this point, but it absolutely earns a place on this list. It’s a match-three puzzler where you drag your thumb to swap candies and create chains, then watch the board explode in colorful combos.
King, the developer behind the game, continues to release new levels every week, and as we head into 2026, there are now well over 16,000 stages on mobile, meaning you’ll never “finish” this game. That’s either terrifying or comforting, depending on how you feel about infinite to-do lists.
