Mega Mine

Mega Mine by Relaxgaming is a video slot set in a cartoonish mining world where sparkling gems and rugged tools fill the reels. The game runs on a 5-reel grid with an initial row setup, but thanks to the Nudging Ways mechanic it can expand up to 8 rows per reel, offering as many as 32,768 ways to win. The central feature is the Nudging Mystery Stacks: special stack symbols with values between 2 and 5 that can nudge up or down, increasing the number of symbols (and thus ways) revealed. When fully revealed they turn into many copies of the same regular symbol. Scatter symbols can also be revealed via those mystery stacks, and landing two or more scatters triggers the Mega Free Spins. You start with six free spins, and each extra scatter adds one more spin. During the free spins round, Nudging Mystery Stacks appear more frequently and may reveal Wild symbols, boosting win potential. There is also a Bonus Buy option — for a fixed cost, players can buy access directly to the free spins feature. The top payout is up to 50,000 times the bet if luck and features align in Mega Mine.

You can play it for real money.
