Lining up a row of three of your pieces isn’t easy because when a piece is added to the board it “boops” all of the pieces adjacent to it, pushing them one space away, including diagonally.

Adding the gray Kitten doesn’t create a line of three. Instead, anything adjacent (yellow area) is pushed one space away.

“boop” or “meow” sound effects are encouraged when you boop. :)

A piece can be booped right off the bed, in which case it is returned to the owner’s pool of pieces.

Pieces can be pushed right off the bed! No secondary chain reactions occur (so Kitten (a) doesn’t move).

A booped piece does not cause a chain reaction when it moves into a new space. Other pieces it moves towards do not move away in reaction.

When any two pieces are already in a line on the board, another piece played into that line cannot push those pieces. This is true regardless of colors of the pieces. (Of course, they CAN be booped from other directions.)

Setting up a line of two and defending against it is an important strategy.

If it had been gray’s turn and a gray Kitten had been placed instead, a line of 3 gray Kittens would be scored on the diagonal.

So, breaking up or blocking your opponent’s line of two is key.

When the orange Kitten is played, Kitten (b) gets booped, but other Kittens don’t move because they cannot be booped into each other. The line of two (or more) prevents it.
