Play X and O for Free

If you've got enough credits you can choose to play on the top game instead; this involves betting either 5 credits or 10 credits per spin of the reels. The Choose Bet button will let you set the stake you want to play with.

If you choose to bet with 5, you'll have eight paylines in play; if you bet with 10 then 14 paylines are in play. However, it's not just the fact that the paylines increase, there's also a rather unusual feature: vertical combinations. Unlike many other fruit slots, betting with 10 allows vertical combinations to be made from the reels too.

You can choose to bet on a certain symbol by clicking on either the X or O buttons. You can choose to bet on both; simply click the X&O button instead. This maxes out your bet to the maximum of 20 credits per spin. This could lead to a maximum payout of 200 credits.

If you're on a winning streak, don't forget to keep an eye on your club meter; there's a maximum limit of 2000 credits so if you're on a roll, you'll need to move some back down to the basic game. This can be done easily by simply clicking on the Collect button.
