nixie is a match-4 game: group identical tiles to remove them.

Player drop randomly draw on a grid. Tiles are numbered from 1 to 9. A special tile named nixie is blocked and cannot be changed except in certain circumstances.

There are 7 stages on nixie, each one of them containing 9 levels with increasing difficulty. To finish a level, the player must complete specific objectives.
Each level offers a unique challenge: player must adapt their strategy or define a new one to reach objectives.
Three infinite levels offer another way to play: go as far as possible and compete with other players via the Game Center
