Adiro is a puzzle or block collapsing game for the iPhone platform. The game objective is to clear the game field by swapping the stars. If two adjacent stars have the same color they will disappear. There are several field sizes and you can change the number of colours. There are two game modes: In standard mode the game ends if you can't collapse any more blocks. All-or-none mode makes the game slightly harder as it will be over if it's impossible to completely clear the field (even if you could do some more moves to earn a higher score).
