Double Stacks

Double Stacks is a NetEnt pokie that Australian players enjoy for its clean, retro style and a clever symbol doubling twist. The whole game turns on stacked symbols that can double up, which keeps a five reel classic lively from spin to spin. Whether you search for the Double Stacks slot or the Double Stacks pokie, it plays in Australian dollars, and it is worth knowing how it works and what its numbers are before you spin.

How Double Stacks plays

Double Stacks runs on five reels, three rows and 10 fixed paylines, so every line is always active and nothing needs switching on. Symbols land in tall stacks, and the signature moment comes when a reel fills completely with a single symbol. Those symbols then double, counting as two in the same spot, so a normal five of a kind can grow into a six, seven or even ten of a kind across the grid. Land enough scatters and the free spins round begins, with wilds added to the reels that can appear stacked as well, spreading the doubling idea further.

Double Stacks RTP, volatility and max win

The published RTP is 96.1%, around the usual level for a NetEnt title. Most reviewers rate the pokie as medium volatility, so wins tend to land at a fairly even pace rather than in rare, huge bursts, while the stacking and free spins still leave room for a standout spin. According to NetEnt, the top payout is worth up to 1,700 times your stake on a single spin, reached when the doubling lines up across a full screen. Medium volatility makes it an easygoing choice for longer sessions with steady action.

Playing Double Stacks in Australia

It is worth being clear about the law here. Under the Interactive Gambling Act 2001, online pokies and casino games cannot be licensed for or advertised to Australians, so any casinos that offer this game operate from offshore and are not locally regulated. The safest way to enjoy Double Stacks is the free demo, which runs in your browser with no account and no deposit and shows the doubling feature in full.

Is Double Stacks worth playing?

Double Stacks is a neat, good looking NetEnt pokie that rewards patience with its doubling mechanic and a genuinely exciting free spins round, and a 96.1% RTP with medium volatility keeps it approachable. It will not suit anyone chasing extreme swings, but as an everyday pokie it holds up well. Whatever you play, set a budget and stick to it, and read our responsible gambling guide.
