If you want to try your luck in casino games than 7 slots are right for you. Did you know that 7 is the world’s favourite number? Yup, they did a huge survey of 44,000 people, and asked them what their favourite number was. The result? You guessed it, number seven. Apparently it’s particularly popular in China, because “seven” sounds like the word “life” when said in Chinese. But think about it, 7 is everywhere! 7 days in a week, 7 deadly sins, and 7 wonders of the world, it’s everywhere! So why is seven a big number in gambling machines? Well apart from being known as a lucky number, it’s thought that it came from other casino games, where if you rolled a seven on the dice, you won. So once casino machines came around, it made sense to bring that into the new style of gaming. Well, for whatever reason seven is thought to be lucky, that’s what you’re going to want to chase in this game of sevens. Three of them in fact! And in traditional casino style, you’ve also got the bars, cherries and bells, 77777 in the mix. Bet one line or three, a dollar a spin, or bet max, it’s all up to you!
