Symbols forming wins disappear, making way for new symbols to drop in that may form new wins. There is no limit to the possible chain reactions.

An inactive cluster of locked tiles, 3x3 in size, is present on the reels. The outer tiles of the Clusterbuster break when winning clusters are formed adjacent to it. Break all outer tiles in a spin to bust open the Clusterbuster and enter Free Spins. The broken parts of the Clusterbuster reset at the start of each spin.

Wild substitutes for all paying symbols.

Prize Diamonds hold a random cash prize representing a stake Multiplier. The possible Multipliers are: 0.5x, 1x, 1.5x, 2x, 2.5x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 25x.

Randomly in a spin, 2 or more Molehills may appear on random positions on the reels. Landing the same symbol on the positions of 2 or more Molehills triggers a trail between them. The symbols where the trail passes are swapped for the symbols that landed on the Molehills. The path is chosen randomly and if it would pass through the Clusterbuster or another Molehill with a different symbol, it will go around them instead. Molehills may randomly appear with a win Multiplier that is awarded if the Molehill takes part in a trail. Multipliers also appear when a trail passes through symbols landed on the reels that are the same as the one that triggered the trail. Additionally, Multipliers may randomly appear when a trail swaps symbols for the one that triggered it. All Multipliers awarded in a spin are added together and apply at the end of all chain reactions to the cumulative win formed in the spin. The possible Multipliers are x2, x3, x4, x5, x6, x7, x8, x10, x15, x20, x25, x50 or x100. If the trail passes through tiles of another type that are a part of a winning cluster, they are swapped for Wilds instead. If a trail passes through Prize Diamonds, their prize is awarded before being swapped. If Prize Diamonds land on 2 or more Molehills, a trail of Prize Diamonds is formed between them. If the trail passes through symbols that are a part of a winning cluster they are transformed into Wilds, holding a random cash prize, similar to those of the Prize Diamonds. All Prize Diamonds on the trail, as well as the ones that triggered it, are awarded and disappear. An additional Molehill may appear in chain reactions, but no more than 5 Molehills may appear in a spin. Molehills disappear on the next spin.

Randomly in a spin where Molehills have appeared, but no identical symbols land on them, the Mole may appear and swap a symbol on a random Molehill for a symbol that matches one of the other Molehills triggering a trail.

Breaking the Clusterbuster positioned in the middle of the reels awards 10 Free Spins. Breaking the Clusterbuster during Free Spins awards 5 additional spins. Additionally, in a spin where 3 or fewer tiles of the Clusterbuster remain unbroken the Mole may randomly appear and break them to bust open the Clusterbuster. In Free Spins any Multipliers awarded when trails are formed between Molehills remain active for the duration of the Bonus round.

The maximum win amount is limited to 10,000x your current stake. If the total win of a game round reaches 10,000x, the round immediately ends and the maximum win is awarded. Where there are remaining spins in the Bonus round, these are forfeited.
