Developer Tamoggemon has released a free version of its forthcoming puzzle game Ballz for bada.

Ballz Free's simple goal is to fill 75% of the playing area with coloured blocks by tapping the screen in the appropriate place.

Things are made more complicated by the addition of an increasing number of bouncing balls which smash into the walls of bricks as you build them, at the expense of a life.

Ballz Free is available now on Samsung Apps, with the full 30 level version expected to be announced in the "near future".
