Double Stacks

Double Stacks is a NetEnt slot that Canadian players enjoy for its clean, retro look and a smart symbol doubling twist. The whole game turns on stacked symbols that can double up, keeping a five reel classic feeling fresh. It plays in Canadian dollars at online casinos, and since many people search for the Double Stacks slot by name, it is worth knowing how it behaves and what its key figures 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 with nothing to toggle. Symbols arrive in tall stacks, and the namesake moment comes when a reel lands completely filled with one symbol. Those symbols then double and count as two in the same position, so a normal five of a kind can become a six, seven or even ten of a kind across the grid. Landing enough scatters opens the free spins round, where wilds are added and can appear stacked as well.

Double Stacks RTP, volatility and max win

The published RTP is 96.1%, about the usual mark for a NetEnt title. Most reviewers place the slot in the medium volatility band, so wins tend to come at a fairly even pace rather than in rare, huge bursts, while the stacking and free spins still leave room for a big 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 pick for longer sessions with steady action.
