Feature drop slots are made by Big Time Gaming and can be found in the well-known Megaways slots. This function makes it possible to activate the bonus with the push of a button. This comes with a price tag, of course, ranging from 25x to 100x the stake. With some slot machines, the price decreases the longer you play the game. You do this by saving different coins or items. This is to keep players involved for longer with a slot machine.
