Bubble Rush 2

Bubble Rush 2 turns the bubble shooter inside out: you shoot from the centre of the board instead of the bottom. Bubbles leave the shooter in every direction and the formations close in from the walls, so you are always working outwards with less room than you had a moment ago. Match three or more bubbles of the same colour to pop them, cut the bubbles holding a cluster up so the whole group drops, and clear the pattern before the rows reach the centre. Free to play, with nothing to download or install - it runs in your browser and in fullscreen.

What separates it from a classic bubble shooter is the pressure the shape creates. The walls rotate, so the next row can arrive from any side, and the arrows around the shooter show which one is about to move - which turns a calm aiming game into a decision about which cluster to break first. Later levels hand you bonus bubbles that change the board in a single shot: one wipes every bubble of a colour, one blasts a whole group, and one burns through everything along your aim line.

Tips for a cleaner board

• Break the supports, not the target. A cluster with nothing holding it to the wall falls on its own, and that costs you less than popping it.
• Keep the centre clear. The rows reaching the shooter end the round, so the middle is the one part of the board worth defending.
• Read the arrows. Knowing which wall moves next is the difference between aiming at a gap and aiming where a gap is about to be.
• Save the bonus bubbles for the colour that blocks the pattern, not for the one in front of you.
