Birds move and collect gems of the same color as the birds themselves, and all feature symbols.
The gems can be upgraded to higher payout levels, up to a maximum payout level of 7.
The upgrade symbol upgrades the payout level of one of the gems 1, 2 or 3 steps.
The upgrade all symbol upgrades the payout level of all four gems simultaneously by 1, 2 or 3 steps.
A collected coin symbol pays its value times the current active bet level. The MAX WIN coin immediately pays the remaining amount required to reach the maximum win.
The wild symbol substitutes for any gems at their current respective payout level. The black bandit wild represents the currently highest paying gem.
A collected dynamite symbol triggers an explosion that explodes symbols and expands the game grid, up to a maximum 8 rows by 7 columns.
The peanut symbol fills empty grid spaces with peanuts when it is collected by a bird. This allows the birds to cross the empty spaces one time each to reach additional clusters of symbols.
A collected transform symbol transforms a cluster of gems next to the bird into the same color as the bird that collected the transform symbol. It may also convert a random number of gems into feature symbols.
Two adjacent birds have a random chance to perform a duel. The birds move apart and then shoot randomly in a number of straight or diagonal directions.
If three or more birds end up adjacent to each other, they will always trigger the duel feature.
A collected key symbol triggers the bandit’s escape feature. The bandit escapes from his cage and lands on the game grid when the birds are unable to collect more symbols.
2 or 4 symbol positions on the left and right sides of the game grid are marked with a train backdrop.
The train heist feature is triggered when a bird collects one of the symbols on top of a train backdrop, and the same bird can collect any of the symbols on top of a train backdrop on the opposite side of the game grid.
1, 2 or 3 feature symbols are awarded before the train stops at the opposite station and the bird disembarks.
The coin game feature is triggered when the entire game grid is cleared during the peanut feature or during the bandit’s escape feature.
Coin bags and scorpions drop in. The birds throw lassos in an attempt to collect coin bags. The value of the captured coin bags is multiplied by the current bet level before being added to the win. A bird that catches a scorpion is out of the game
Three bonus symbols collected by the birds during a game round trigger the free drops bonus game.
The grid size, the progress on the symbol collection meter, the collection of additional bonus symbols and the payout level of the gems are all persistent during the bonus game.
