Atomic Slot Lab, an in-house studio of Bragg, will release the slot Fabulous 777s on April 16, 2026, delivering an authentic 3‑reel, 1‑line stepper experience amplified by a progressive jackpot feature. Normal and fiery sevens alongside single, double, and triple bar symbols evoke the golden age of slot machines.
One payline
The game uses a 3×3 layout with one payline, where wins pay left to right on adjacent reels. The incremental bonus prize, shown above the reels, starts at a default value of 333.3x the bet and increases by 1% of each player’s bet on every spin. Landing three fiery sevens awards the current bonus value, after which the prize resets to its default.

The incremental progressive bonus serves as the game’s central feature, rewarding persistence and dedication. The classic stepper design offers timeless appeal with a modern twist. Specifications include a 3×3 grid, one payline, and a default incremental bonus value of 333.3x the bet.
