Yoker lets you place eggs as jokers on the game board (5 instances per game). Yoker eggs can be used to make lines combining groups of different type birds as long as the two groups placed on either side of the egg can be combined to make a total of 5 or more chickens.

Click on Yoker to activate, then click on a bird on the game board.

The chicken is replaced with an egg. In the example below the egg has made 2 lines: one line of green chickens and one line combining pink and violet chickens.

In addition to Yoker eggs, eggs may also be randomly added to the game board as the game progresses (e.g. after a move). Eggs are shown as multicoloured swatches on the next up panel.
