Invictus, a Latin word meaning things like invincible, unconquered or undefeated, is the title of a thought-provoking online slot by software provider Hacksaw Gaming. This is a game which explores intriguing subject matter while delivering a batch of equally intriguing gaming techniques. It's a slot that might get into your head if you let it, but one which can also trigger visceral thrills via a host of multiplicative abilities, Olympian Respins, and three bonus rounds, each one better than the last in terms of power creep.
