Slot machines, being based around a mechanical system rather than cards or dice are a relatively new introduction to gambling, but have quickly become one of the most popular. Although they can look very different and have vastly different payouts, all slot machines have the same basic principles, to line up the symbols in the combination shown on the Payout Table.

The other main difference between the differnt machines is in in the two categories: Progressive Machines and Straight Slots. Straight Slots are programmed so that they always pay out a pre-determined value, whereas Progressive Machines continue to accumulate and increase the jackpot until it is won.

The stakes for UK Casino Slots is much higher than the machines found in pubs and clubs. Currently, the maximum bet for an individual machine in a pub is £1, but in the casinos you can bet as much as £35.
