Is a cascading free slot demo game played on a 5x5 grid. Symbols drop down in the grid to form winning combinations. Wins are achieved by getting 4 or more symbols in a connected cluster where they touch each other horizontally and/or vertically. Winning symbols are removed and new symbols drop in to fill up the grid. The game continues to cascade until no new winning combinations can be created. The aim of the free round is to complete the collection challenge and win along the way. The collection involves collecting a certain number of specific types of symbols. These symbols are collected when they form part of a win. Wilds do not count towards the collection in the free round. There are 3 levels to the collection. Level 1 requires players to collect 16 of a specific low pay symbol and 6 of a specific high pay symbol, and will trigger the Elixir of Power Bonus, at the end of the free round. Level 2 requires players to collect 21 of a specific low pay symbol and 11 of a specific high pay symbol, and will improve the prizes available in the bonus. Level 3 requires players to collect 26 of a specific low pay symbol and 16 of a specific high pay symbol, and will improve the prizes available in the bonus again.
