LOTTO Lucky™ by Revolver Gaming is a 3D slot built around a lucky charm theme and a 3x3 base game grid. The main feature is the Lucky Symbol mechanic: one of 10 eligible symbols is selected for each spin, and if three or more Lucky Symbols land, they lock in place while the remaining symbols re-spin. Collected Lucky Symbols are then paid together, with the final pay doubled.
The game also includes a second-screen LOTTO BONUS round. In this feature, players choose lottery balls that can award credits and multipliers, adding a separate bonus game to the standard spin sequence. The slot is available in multiple languages and uses HTML5 technology, with an RTP of 95.95%.
A demo version is available to play for free, which allows users to study the mechanics, symbols, and bonus rounds before playing for real money.
