Reels Pumpkins Ultra Up by Lightning Box is a Halloween-themed slot built on a 3x5 reel layout with 40 paylines. The game uses a Hold and Spin feature that can be triggered by landing six or more pumpkin symbols. During the feature, pumpkins stay in place while new symbols can land to complete the round.
An Ultra Up symbol can appear on a pumpkin and level it up, increasing the value linked to that symbol. When the Hold and Spin round ends, the held pumpkins reveal the prizes collected during the bonus. The game is described as having high volatility, with a base game hit rate supported by two features that may occur frequently.
This demo version lets players play for free and practice before playing for real money. It is a review-style introduction to the main mechanics, including the pumpkin symbols, the Hold and Spin round, and the Ultra Up upgrade feature.
