How to implement dart game?

I tried to implement dart game, Now my thought is have 1 collider on the tip, when the tip touches the the board, I set the rigibody Kinematic to false, so it will stop,

One problem is when the dart hit the board at >90 angles, it will stick on the board too. I also want the dart can hit other objects such as human, so I cannnot use the angle between board forward vectors and darts forward vectors. If I use the mesh face vectors, I guess there will be much calculation? Anyone has a good solution?
