I played as the blue player, and this happened to me twice:
When a red piece is on the first spot of the yellow line, and I try to 'eat' that piece, it glitches so that the two pieces are together as one, and then the red one automatically eats mine.
I haven't seen this happen for other colors, it was just specifically the red piece on the yellow line while playing as a blue player.
Other than that, the game is entertaining if you don't have friends to play with! :D
