The most popular features in the Emerald lands are the Win Multiplier, which can randomly increase by 1 on every dry spin, and the Mini Slots Feature that brings a bunch of little slots machines on the screen.
The Win Multiplier
In the top right corner, you will see a multiplier that increases with every non-winning spin. The starting multiplier is 1x and it increases by 1 every time the reels do not bring you a win. This multiplier applies to the total win of the spin and it goes back to 1x after it applies to a win.
The game saves the multiplier for every bet you set. Thus, if you change the bet, you will start from a 1x multiplier again. Select an older bet and you will probably play with a higher multiplier.
The Mini Slots Feature
The reels can change their color into green randomly, on any spin. The key to triggering the Mini Slots Feature is to make all 5 reels turn green. The feature starts with a payout of 2x total bet.
During this round, up to 15 mini slot machines can appear randomly on the screen, covering the reels entirely. However, these mini slot machines can also come in a 2×2 or a 3×3 format. Regardless of their size, all slot machines bring multicolored Lucky 7 Symbols on the reels and an additional random multiplier that applies to the total win.
Each mini slot machine spins individually. If you hit 3 Lucky 7 Symbols, the game rewards a new spin, giving you the change to land Lucky 7s once again. The round ends when all mini slot machines have stopped spinning. The game adds all wins and awards the total amount.
