Dice Nim Game is a gamble in the Kakegurui Twin manga played between Sakura Miharutaki and Mary Saotome supervised by Aoi Mibuomi. It happens during the Treasure Hunt.
Rules[]
The rules are very simple (stated by Aoi Mibuomi). Using dice and go stones, two players take 1, 2, or 3 coins from the "center pile". Whoever takes the last coin loses. But Aoi Mibuomi switches the rules that Mary Saotome, also Sakura Miharutaki will only use a due to add a random element, also throwing the die, then taking that number of stones from the pot, then whoever takes the last stone is the loser. Aoi in the end also specifies that cheating was never prohibited.
Game[]
After Aoi explains the rules, the game kicks off! But before they start, Mary asks to examine the die. As she does, Tsuzura Hanatemari walks out of the room, slamming the door behind her, allowing Mary to slip in a normal die in case of the original die being loaded. The game starts with Mary rolling a 2. Sakura then rolls a 5. The game continues on and the stones in the pot are running low. Yukimi Togakushi then runs out, slamming the door just as Tsuzura did, this time allowing Mary to slip in a loaded die that always lands on 6. Mary then rolls a 6, pulling the last stone from the pot. Mary's cheating is then revealed by Sakura. Mary asks how she still lost, and Sakura says that she suspected Mary cheating, so she took out a stone in advance. Sakura is declared the winner.
