Play Stacks of Riches Slot for Free & Review

Stacks of Riches is a simple fruit machine from Relax Gaming. It’s played using a 5 reel, 3 row, 10 payline game engine with winning combinations created from both right to left as well as left to right. The main extra here is the duplicating reels feature which has the potential to deliver some chunky rewards. Play on all devices from between 10p and £100 per spin.

The set up in Stacks of Riches is very straightforward. The purple pastel reels feature a selection of classic fruity symbols.

The lowest paying symbols are the grapes and plums which pay 0.5, 1 or 2.5 times your stake if you land 3, 4 or 5 on a line. Next come the lemon and melon which award 0.6, 1.5 or 4 times your stake. The cherries are next at 0.8, 2 or 5 times your stake followed by the bell which pays 1, 2.5 or 6 times your stake.

Land 3, 4 or 5 of the lucky red 7 for a payout of 2.5, 7.5 or 12.5 times your stake. The best of the payout bunch is the diamond which will get you 5, 20 or 30 times your stake. There’s also a wild. The win both ways game engine means that winning combinations can start from both reel 1 and reel 5.

The only extra on offer in Stacks of Riches is the Stack Duplication feature. This becomes active if you land stacks of the same symbol on reels 1 and 3 or on reels 3 and 5. The symbols on the reel in between then transform into the same symbol as on the other adjacent stacks to create a bigger winning cluster.

That’s pretty much it. The design is simply done. It’s all neat and tidy but not especially flashy. Likewise, the ambient style backing track. The gameplay is as basic as the design. The duplicating stacks can spice up the action though, especially if you land 1 of the higher value symbols.

If you’re a fruit machine fan, then Stacks of Riches does the job. If you’re expecting anything more than that then, you’ll find better alternatives elsewhere – such as Relax Gaming’s Zombie Circus.
