Alien Mahjong is an addictive space-themed Gorilla-style mahjong puzzle game in which you'll be looking for pairs of aliens. Click the arrow to get started. On the screen, tiles depicting aliens, blasters, astronaut helmets, spaceships are laid out in rows in several layers. Look for groups of identical tiles, numbering 2 or more, side by side. Click on them to remove. After removal, the lower layer will open, and the upper rows will fall down. Calculate so that after the collapse, new groups are formed. The light bulb at the bottom will give 3 clues. When there are fewer blocks, you will be able to undermine the interfering bombs. Clear the field to move to the next level.
