In this paper, we investigate using cards (such as business cards or mahjong tiles) with the same design on the back, but the front sides can face different directions. These cards are defined as those whose backs are indistinguishable and whose fronts can be differentiated based on the top and bottom. Mahjong tiles, painted the same color on the back, cannot be differentiated from the back even when swapped. Thus, tiles whose fronts show different designs when swapped can be used as top and bottom cards. Here, we examine the practical feasibility of implementing such protocols, focusing on whether the shuffle is practical. We present a realistic method to determine if protocols using up-down cards can be implemented by replacing cards with mahjong tiles.
