An inactive cluster of locked tiles is present on the slot. The outer tiles of the inactive cluster unlock if winning clusters are formed adjacent to it. Break all outer tiles to bust open the cluster and reveal its prize.

Dragon Eyes Progress

The game features are locked at the start of the game. To unlock them you have to hatch the Dragon Eggs which are represented by the 3×3 cluster in the middle of the slot. Only one Dragon Egg will be active at a time.

The game progresses in three stages represented by the three initially locked Dragon Eyes above the reels – one for each of the locked features. If a cluster win occurs next to the Dragon Egg, the adjacent parts of the egg are destroyed. if all of its parts are destroyed the egg hatches its corresponding feature and a Dragon Eye appears above the slot to indicate that the feature is now available.

If a feature is unlocked it is triggered in the next spin and the next egg is placed in the central cluster ready to be unlocked in the same way. 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.

In the case of another feature triggering together with the Blue Hatchling feature, the Blue Hatchling feature is executed first, and the other features are executed after the new tiles drop down.

The order to hatch the Dragon Eggs is:

Blue > Green > Purple.

After these eggs are hatched a Fire Egg spawns in the middle and will not be replaced after it activates. The Fire Egg awards 10 free spins every time it is hatched.

Dragon Eggs

Blue Hatchling
Triggered if level 1 of the progress is completed. Triggers randomly in future spins. If this feature is triggered the Blue Hatchling flies above 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 if level 2 of the progress is completed. Triggers randomly in future spins. If this feature is triggered the Green Hatchling flies above the slot and adds a random number of wilds to the screen. Up to 20 wilds may land during a spin. Wilds substitute for all paying symbols.

Purple Hatchling
Triggered if level 3 of the progress is completed. Triggers randomly in future spins. If this feature is triggered the Purple Hatchling flies above 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.

Free Spins

Triggered every time the Fire Egg is unlocked and it grants 10 free spins. The egg cluster is not present on the reels during the bonus round. During free spins 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.
