Bubble Shooter

Bubble Shooter is one of those puzzle games that stays appealing because the goal is so clear. Match three or more bubbles of the same color, break clusters, and keep the board from closing in on you. It starts calmly, then gradually asks for more careful planning.

Good shots matter, but so does patience. Sometimes the best move is obvious. Other times you need to use the walls, set up a drop, or clear a path for a color that has barely shown up. That small layer of strategy is what keeps the game from feeling mindless.

It is easy to play in short bursts, and it still works when you want to settle in and chase a better score. There is nothing complicated about it, which is probably why it lasts.
