Angle Race

A Parcheesi-like game where you make the angle you roll.[br][br]Rules:[br]Roll the angle and move either your open or solid point - [br]but not both - to make that angle. Your solid point should[br]always be counterclockwise from your open point.[br]If either of your points lands on the same dotted line as an [br]opponent, you can move them back 5° or yourself forward 5°.[br]If you roll the angle you've got - skip the turn. UNLESS you're [br]in last place, then roll again![br]When someone crosses the finish line, everyone else gets [br]one more roll.[br]Winner is the player to get their solid point counter clockwise [br]the farthest past the starting line.
