Celtic Mahjong Solitaire

Celtic Mahjong Solitaire is a mahjong game with a Solitaire variation ruleset. Match tiles with each other to remove them from the board, but make sure that both tiles have a free space on either their left or right side (you won't be able to highlight them otherwise as it's an invalid move). Clear the board in as little time as possible and try to beat the high score!
