Some of Asia’s most mighty waterways form the backdrop to China River, a 5 reel, 3 row, 30 payline video slot from Bally Technologies. This Chinese-themed title comes with mystery stacked symbols and a free spins bonus feature. Play from between 30p and £30 per spin.

As you’d expect from a slot named China River, there’s a distinct Asian flavour to this live casino conversion. Symbols on the reels include a green frog, an ornate plant pot and a water lily. The biggest payer is the Chinese character which will give you 1,000 times your line bet if you find 5 in a payline. They’re joined by the standard playing card symbols from ace down to nine. The bird is the wild symbol and appears on reels 2, 3, 4 and 5. It substitutes for all other symbols.

China River also comes with Mystery Stacked Symbols – on each spin, 1 symbol will be randomly nominated as the mystery symbol and fill all of the mystery symbol positions on the reels. This means you can get multiples of the same symbol throughout the reels which can send the win column rocketing. The only symbol that can’t fill the Mystery Stacks is the wild.

If you hit 3, 4 or 5 coin symbols on a single payline you’ll trigger the Free Spins Bonus feature. Once hit, you’ll be awarded 8, 10 or 15 free spins – the bonus can be triggered on multiple paylines on the same spin. If that happens, you’ll receive multiple chunks of spins.

As the coin symbol can fill the Mystery Stacks, it’s possible to get a massive chunk of free spins. I’ve managed to hit 58 free games from a single spin. It’s possible to get even more free spins during the bonus round. And if all that wasn’t enough already, all wins during the feature come with a 2x multiplier and are doubled.

There are plenty of Chinese-themed slots for online casino players to choose from so is China River worth closer investigation? Most definitely yes. The graphics are simply drawn, the soundtrack matches the theme nicely and the gameplay is silky smooth.

The Mystery Stacked Symbols are a nice addition offering plenty of chances to bag a big win. Throw in a quality free spins round, complete with the double wins and this is one river you’ll definitely want to take a trip down. If you like Asian-themed slots, Choy Sun Doa by Aristocrat is very good as to is Thai Temple by Playtech.
