Clusterbuster™ is a Red Tiger innovation where an inactive cluster of locked tiles is present on the slot. The outer tiles of the inactive cluster unlock when winning clusters are formed adjacent to it. Break all outer tiles to bust open the cluster and reveal its prize. As part of Chain Reactions, symbols forming wins disappear, making way for new symbols to drop in that may form new wins.

Dragons don’t give up their gold easily! Features are locked at the start of the game. You’ll have to hatch the Dragon Eggs to unlock them. Unlocking a Dragon Egg reveals a Dragon Eye at the top of your screen to show your progress. There are three eyes to unlock; one for each of the locked features: Blue, Green and Purple.

How do you like your Dragon Eggs in the morning? Dragon Eggs are represented by the 3x3 cluster in the middle of the slot. When a cluster win occurs next to the Dragon Egg, the adjacent parts of the egg are destroyed through the Clusterbuster™ mechanic. When all the Egg’s parts are destroyed, an exciting feature is unlocked. The unlocked feature is then triggered in the next spin. The next Egg is then placed in the central cluster, ready to be unlocked in the same way. The first Dragon Egg is blue, the second is green, and the third is purple. After these eggs are hatched, a Fire Egg spawns in the middle and will not be replaced after it hatches. The Fire Egg awards 10 Free Spins every time it is hatched. All unlocked features may trigger randomly in future spins. More than one feature may trigger in the same spin if there is more than one feature unlocked.

- Blue Hatchling: Triggered when level 1 is unlocked, and randomly in future spins. The Blue Hatchling flies over the slot and destroys all low-paying symbols, removing them from the reels. Only high-paying symbols will land in the first of the following cascades. - Green Hatchling: Triggered when level 2 is unlocked, and randomly in future spins. The Green Hatchling flies over the slot and adds a random number of Wilds to the screen. Up to 20 Wilds may land during a spin. - Purple Hatchling: Triggered when level 3 is unlocked, and randomly in future spins. The Purple Hatchling flies over the slot and adds a Lightning Multiplier to a random number of symbols. Multipliers may be applied to up to 13 symbols during a spin. The possible multipliers are: 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 30x, 50x, 80x, 100x. If multiple symbols in a winning cluster have multipliers applied, their values are multiplied by each other but cannot exceed 100x per winning cluster. - Fire Egg: See the section on Free Spins.

Free Spins are unlocked by the final Egg: the Fire Egg… the ultimate Egg. When the Fire Egg is unlocked it grants 10 free spins. During Free Spins, the egg cluster is absent on the reels during the bonus round. There is an increased chance of triggering one or multiple Hatchling features. No retriggers of Free Spins are available during the bonus round, but at the end of Free Spins the Fire Egg locks again and may be unlocked in future spins for another 10 free spins.

A symbol is part of a cluster if it lands horizontally or vertically adjacent to a matching symbol. Five or more identical symbols appearing in a cluster award a win. Winning clusters disappear to allow the above symbols to fall into place, giving the chance of even more wins in each spin.
