KMahjongg
5.0 ho linaleli tse 5 (ho ipapisitsoe le tlhahlobo e le 1)
In KMahjongg the tiles are scrambled and staked on top of each other to resemble a certain shape. The player is then expected to remove all the tiles off the game board by locating each tile’s matching pair.
That game is not asking for anything from me, therefore it is trade-free.
