The lucky seven has been the star symbol on slot machines for generations, and 777 across the payline is still the picture most people have of a jackpot. These free slots are all built around it — from IGT’s Triple Red Hot 777 to Bally’s Blazing 7s family.

About 777 Slots
Most 777 slots are classic three-reel games: sevens in two or three colors, single, double and triple bars, and a wild multiplier. Mixed sevens (any color) pay a small prize; three of the same color pay the big one.
Newer 777 games keep the symbols and add a wheel or free spins on top — the Wheel of Fortune Gold Spin and Quick Hit Blazing 777s machines are good examples.
