The Curious Machine Slot Features

setting

The Curious Machine Slot offers several exciting features designed to enhance the gameplay experience. One of the standout elements is the VORTEX symbol, which can actually appear on reels 2 or 4 and triggers the VORTEX feature. When activated, the icons rotate a random number of times around the VORTEX, potentially leading to extra wins. The VORTEX symbol also acts as a wild, further boosting winning potential. If only one VORTEX symbol lands, it may remain in place or move to the third reel, depending on what’s most beneficial. Two VORTEX symbols simultaneously trigger the activation of the VORTEX on reel 4.

Another intriguing feature is the second-chance reel, which kicks in when no winning combinations occur and offers a chance to complete a 5x win with any symbol. Additionally, landing three DINOSAUR symbols on reels 1, 3, and 5 triggers the FREE SPINS feature, where players are taken back in time, earning random multipliers (1x to 5x) on each spin, though bonus round wins are not multiplied. Free spins can also lead to additional spins.

For those looking to take a risk, the Double Up feature allows bettors to double their win after any successful combination. By selecting which of the robot's hands contains a coin, players can collect their winnings or gamble for a chance to double up.

Lastly, the TRAVEL THROUGH TIME bonus feature is activated by landing three specific symbols on reels 2, 3, and 4. This exciting second-screen bonus feature lets players join Miles and his robot companion as they escape the General’s watchful eyes in a time-traveling adventure.
