Double Stacks

Double Stacks is a NetEnt pokie that has found a steady following among New Zealand players who like a clean, retro slot with a clever twist. The whole game turns on stacked symbols that can double up, which keeps even a five reel classic feeling lively. It runs happily in New Zealand dollars at online casinos, and because plenty of Kiwis search for the Double Stacks slot or the Double Stacks pokie by name, it is worth knowing exactly how it behaves and what its numbers are before you spin.

How Double Stacks plays

Double Stacks uses five reels, three rows and 10 fixed paylines, so every line is always active and there is nothing to switch on or off. The symbols arrive in tall stacks, and the signature moment comes when a reel lands completely filled with a single symbol. When that happens those symbols double, counting as two in the same position, which means a normal five of a kind can quietly become a six, seven or even a ten of a kind across the grid. Landing scatters opens the free spins round, where wilds are added to the reels and can themselves appear stacked, stretching the doubling idea across more of the screen.

Double Stacks RTP, volatility and max win

The published RTP is 96.1%, which sits around the usual mark for a NetEnt title. Most reviewers place the pokie in the medium volatility band, so wins tend to arrive 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 a comfortable choice for longer sessions where you want frequent action without relying on one big hit.

Playing Double Stacks in New Zealand

You can play Double Stacks in NZD at the online casinos listed on this page, all of which offer the game.
