The creation of a 1-sided die seems like a practical joke reserved solely for special occasions such as April Fools' Day. Yet it is a surprisingly practical design that could have easily been created years ago. The 1-sided die is made for specific albeit common situations such as one encountered in Dungeons & Dragons, as detailed by the designers of the 1-sided die, "There’s a room with a pie in it, and the pie is guarded by an orc. If the characters open the door, one of these things happen: 1. The orc attacks. That’s it, there’s only the one option."
Created by Awesome Dice, 1-sided die allows players to move on quickly instead of continuously rolling a 4-sided die until it lands on a one. It allows this be taking on a Mobius strip shape.
