Disco Danny is a NetEnt video slot built on a 3x3 reel layout with five fixed pay lines. The game uses a high-volatility model, with a return to player listed at 96.04% to 96.93% and a betting range from 0.1 to 75 credits. The interface adapts to the device screen, and the demo version lets players play for free and practice before playing for real money.
The paytable is based on matching symbols across the fixed lines, while two scatter symbols shape the bonus features. A Silver Scatter can appear in the base game, and a Golden Scatter can land in both the base round and free-spin rounds. In the main game, a Golden Disco Ball can trigger an instant win of 10x or 20x the current bet.
Three Golden Balls in one spin activate the free spins feature, which begins with five spins and five multiplier levels: x1, x2, x3, x5 and x10. During the bonus, collecting more Golden Balls adds to the total win, resets the counter to three spins, and filling all nine reel positions advances the multiplier to the next level.
