First, you choose the colour you like from these four.

then we need throw the die one by one, and the order is red, yellow, green and blue.

When you got six, you plane can leave from the base, since you get the six you have one more chance to use the die, If this time you got the points less than 5, then your plane can move by 5 steps, if 4, then 4 steps. then give the die to the next person
If this time you still get 6, you got 2 choices, first let your another plane go out, then throw the die again, second you can move the original one by 6 steps, then throw the die again.

When you catch up with others' plane, you can attack it, then it will be destroyed and be put into the base again until others got 6 points.
If another player got 2 planes, you just can destory one, then your own plane will be destoried as well, so both of you need to put the plain into the base.

Anyone who lets all the planes go the target first is the winner
