Pragmatic Play should be applauded for going their own way rather than following the conventional technique of collecting winning clusters to trigger features when it comes to grid slots.
Game Symbols
The Chicken Drop slot has a bucolic, rustic environment with a farm motif. The design here is pretty simple, yet it works quite nicely. Spade and heart symbols occur with toadstools, corn ears, acorns, and blueberries in the game's grid. The strawberry symbol is the highest-paying symbol. The bonus symbol is a treasure chest. Eggs, watering cans, and four-leaf clovers are all included in the upgrading features.
Bonus Rounds & Free Spins
The tumble function is at the heart of the action, as it eliminates winning clusters from the game board and replaces them with fresh symbols. This can result in several victories from a single spin, with the game only finishing when no fresh winning clusters appear.
When the watering can or four-leaf clover symbols emerge, the progressive features begin. The larger the space, the more cans there are. When no more upgrades or clusters are visible, an egg symbol is placed on the grid, transforming all symbols in the highlighted region into the same matching pay symbol, resetting the tumble mechanic.
When 4 or more scatter symbols appear on the screen, you'll be awarded up to 20 free spins. When 4 or 5 scatter symbols appear on the screen, the feature can be retriggered endlessly, adding 5 more spins to the total. Upgrades that are in place at the time the feature is activated are carried over and don’t reset for the length of the feature.
