In Contest of Champions, each player will roll 6 dice on their turn with up to two re-rolls. There are two die faces, mutant and science, which automatically lock and cannot be rerolled. These won’t do anything harmful unless you end your turn with three or more. Three mutant dice will see you sent off to the Crystal Prison location, ending your turn. A trio of science dice will cause an explosion, damaging you and everyone at your location.
The other four faces either earn you a point, allow you to attack an enemy at your location (which causes them to lose a point), attack an enemy at another location, or move locations. The only additional rule is that to move locations, you have to spend a number of dice equal to the characters on your current location.
Each location has a special ability that affects the players there and a number of points you earn when you reach that location. Each superhero has special passive abilities as well as unique power cards that can be activated if you roll the needed results with your dice.
If at any point during a player’s turn they reach 21 points, they immediately win the game. Otherwise, play continues until someone does or all but one player has been eliminated from the game.
