Mahjong in Poculis is a version of an ancient solitaire tile-matching game. The rules are simple: You are welcomed with a layout of overlaid tiles, which you are supposed to make disappear by matching those with identical symbols. The challenge comes from the rule that states that only free tiles can be matched into pairs. The goal is to remove all tiles from the board. If you are not familiar with the rules, however; there is no reason to worry, as there is a tutorial to teach you the basics.
It is good that the game comes with six different themes: Christmas, Halloween, Asian, Easter, Wonderland and Future. Each of these themes comprises its own layouts, style and sounds. Unfortunately, the graphics are not so good, which causes some strain to the eye. Likewise, I find the music somewhat annoying, so you are free to turn it off.
If you are a beginner, you will probably be pleased to know that the game has three playing modes: Novice, Standard and Expert. Moreover, there are more than 300 levels. Luckily, there are challenges that give you extra scores, such as matching a sequence of pairs. Finally, the game can keep your scores and post them to a world ranking.
All in all, the developer has managed to recreate the popular Mahjong game quite realistically. However, I regret to say that there are better looking variants of the game around. The product is free and downloadable from the Mac Store. Optionally, you can acquire a license as an in-app purchase.
