Arabela is an iPhone and iPod Touch variant of a popular logic tile-based puzzle game from the near past. It is reported to have more than 3, 000, 000 fans worldwide. The game is suitable for children and young players and yet challenging for adults.
You play by tapping anywhere within an area of adjoining tiles from the same color which removes them from the board causing the remaining tiles to collapse into the empty space. There is no score to keep, rather the goal is to remove all tiles from the board. This is a lot harder than it seems. Rules are simple but the simplest rules make the great game.
The game has proven to be highly addictive (WARNING: Play at your own risk!) and will hold your attention for many days to come.
