I was recently introduced to allbrickbreaker.com, which allows you to play brick breaker games for free. They provide several Flash-based brick breaker clones that you can play directly on their Website.
The games are ad-supported. Before playing you will see (at the moment anyway) a 30-second ad. Despite this, the interface is relatively clean and uncluttered, unlike every other Website I’ve ever seen hosting Flash-based brick breaker games. This was refreshing to see for a change.
My personal favorite brick breaker online game is still AlphaBounce, however AlphaBounce takes a while to get into. You have to gradually build up your “character” over time.
If you’d rather just play a quick game of brick breaker, allbrickbreaker.com is a good option. There are currently 8 different games to choose from on their Website. Enjoy!
