Spinning Top Dice

Read full description

Traditional dice are designed around cubes, which are limited and cannot meet the needs of all numbers of sides. Now, this dice has been born, combining a spinning top and a double cone, completely breaking the shackles! From 3 to 100 sides, the double cone dice can achieve even distribution and is completely fair. Whether you are a board game enthusiast, a mathematical researcher, or a player seeking a novel experience, this dice can meet your needs. Come and download my app and experience the infinite charm of the double cone dice! Note: This dice uses the lowest side as the result side.
