You do not need to roll the die when:

• your opponent played a blue card and you reply with a blue card,
• your opponent played a blue card without a slice effect and you reply with an orange card,

Stars are used to reduce the difficulty of your strokes as follows:
On serve: 1∗: -2 // 2∗: -4
Rally Points: 1∗: -3 // 2∗: -5 // 3∗: -7

Some cards apply an effect to the ball (you can also add an effect on your serve):
Topspin: after replying a stroke with a topspin effect, a player will have to discard 1 card to move to the volley zone.
Slice: when receiving a ball with a slice effect, increase the difficulty of all orange and red strokes by +2 (except volley)
