Bubble Shooter

Bubble Shooter is one of those games that needs no instructions and no patience to start — you point, you shoot, and coloured bubbles burst off the ceiling. It has been a browser staple for over two decades, and the appeal has not changed: every shot is a small, self-contained puzzle you can solve in a second, and the board keeps creeping down to remind you the clock is real.

Each level starts with a grid of coloured bubbles anchored to the top of the screen. You fire from a launcher at the bottom, and any group of three or more matching colours that touch will pop. The detail that separates a decent player from a good one is what happens next: bubbles hanging below the popped group lose their anchor and drop too. Chasing those chain drops, rather than popping the first match you see, is where the real scoring happens.

The bank shot is the other skill worth learning. Shots ricochet off the side walls at a true angle, so a colour that looks unreachable behind an overhang is usually one wall bounce away. Lining up a rebound to clear a support bubble and collapse an entire cluster is the most satisfying thing in the game, and on later levels it stops being a flourish and becomes necessary.

Levels tighten gradually. Early boards are wide open and forgiving; later ones mix in tight columns, awkward colour distributions, and a ceiling that advances after a set number of shots. There is no timer counting you down, so you can take as long as you like lining up a shot — the pressure comes from the board itself, not from a stopwatch.

The campaign runs through four worlds of eight levels each — Crystal Cave, Coral Lagoon, Aurora Peaks and Star Nebula — and each board is laid out in a pattern rather than a random spray: stripes and paired clumps to start a world, then columns, diamonds and fully mixed boards as it closes. After the fourth world the levels keep coming: the late boards return in a fresh order and new colours, with the ceiling coming down a little faster, and a new world light every eight levels.

It runs entirely in your browser with nothing to install, and works the same with a mouse or a touchscreen, which makes it a natural fit for a spare few minutes on a phone. If you like it, Mahjong Solitaire and Mystic Match scratch a similar match-and-clear itch at a slower pace.

Clear every bubble on the board to finish the level — the plate at the top shows how many remain. Move your mouse or finger to aim (a ghost bubble shows exactly where the shot will land), then click or tap to shoot; on a keyboard use the arrow keys and Space. Tap the small bubble marked SWAP (or press X) to trade it with the one in the launcher. Match 3 or more bubbles of the same colour to pop them, and watch the down-arrow counter under your score — the ceiling comes down every few shots.
