Remove groups of the same coloured blox and try to get as a high a score as possible. Tactical brain game with a halloween theme! Instructions: The aim of the game is to select and remove blox of the same colour. To select some blox, click once. The blox will be highlighted. To remove it click the same blox again. The larger the group you remove the more points you will get. When a group of blox are removed, the other blox fall, and then slide across to fill any gaps you have made. The column on the left of the screen shows the next column to slide in sideways. Good luck!
