There are three types of giveaways that can be hosted with Giveaway bot.
Over the course of your set duration, users will be able to enter the giveaway by reacting to a message with the emoji you specify. After the time is up, the winners are drawn.
The first x people to react have a 100% chance of winning the giveaway.
The winners will be drawn when the maximum allowed amount of entries are reached or the duration runs down, whichever comes first.
*these types of giveaways can only be made when using the giveaway builder
