Double Stacks

Double Stacks by NetEnt is a five-reel, three-row slot with 10 paylines and a maximum win of 1,000x the stake. The game uses a classic fruit machine style, with symbols such as bells, BARs, sevens, cherries, lemons and diamonds. Matching wins are formed from three or more symbols from left to right across an active payline.

The key features are the Double Stacks mechanism, Wild symbols and a free spins round. When a reel lands as a full stack, the Double Stacks feature doubles the symbols on that reel. Wilds substitute for other paying symbols, while Scatter symbols can trigger free spins: three Scatters award five free spins, and five Scatters award 30. During the bonus, additional Scatters can add more spins, and stacked Wilds may appear.

This page offers the demo version, allowing players to play for free and practice before playing for real money. Stakes range from 0.10 to 100 per spin, with high-volatility gameplay and a paytable built around stacked symbols and bonus-triggering Scatters.
