Some games could be described as being Ronseal slots – they do exactly what they say on the tin. Wild Rubies from Bally Wulff is one such game. Played using a 5 reel, 10 payline engine, this old-school fruit machine comes with special stacked wild ruby symbols which are central to the action. Play from between 10p and £20 per spin.

We don’t normally associate Bally Wulff with classic fruitys but Wild Rubies is so stripped back it could come from the Novomatic catalogue! The design is as retro as it gets – the plain purple reels include lemons, plums, oranges and cherries which award payouts of 0.5, 25 or 10 times your total stake if you land 3, 4 or 5 on a payline.

Next come the grapes and melons which award 1.5, 5 or 20x and the bells and bars which pay 2, 7.5 and 25x. The most rewarding symbols are the double bar and the lucky 7. Land 3, 4 or 5 of these in combination and you can look forward to 2.5, 10 or 50 times your total bet.

The key to all of the best action is the wild ruby – this shimmering red gemstone is the game’s wild. It can land on all reels in stacked formation and replaces all other symbols. Find 3, 4 or 5 of these on a single payline and the cashier will ring to the tune of 5, 50 or 200 times your total bet.

That’s all there is to report as far as gameplay goes. We said this slot was stripped back and it certainly is – there aren’t any bonus features to speak of.

Despite the lack of extras, we found the pace of Wild Rubies to be pretty brisk, thanks largely to the presence of the stacked wilds which hurried things along. Land multiple stacked wilds on the same spin and some very decent results are certainly possible.

This slot is aimed squarely at lovers of classic fruit machines. There are no added frills on offer here. If you want bonus features, Bally Wulff’s The Land of Heroes is recommended.
