Shamrock Lock Jackpots and Bonuses

Shamrock Lock has a base game payout that can award 100,000x the bet! There are also some super bonus features that add to the experience and offer additional opportunities to collect some cash. The Fortune Bet and Lock ’n’ Roll is an exciting feature. You can activate the Fortune Bet, which increases the wager by half. This provides a chance to trigger the Lock ’n’ Roll feature. This can occur at random with any spin. When this happens, the first 3 reels will lock together and will contain the same symbol. The Wonder Spin is also a nice addition to the game. Wilds can appear stacked and if this happens on the third reel, the Wonder Spin will start. Here, 2 re-spins are offered. The first offers wilds on reels 2 and 4. If no win is collected, the second spin is played. This will offer wilds on reels 1, 3, and 5 and has a guaranteed payout.
