I found the secret to it, so I made this game. Get new and old guys from 1 and 2. Press space to roll. Right arrow to increase fast and left arrow to decreese fast. (Fast is how many seconds you wait after each roll). Press ? to see guys (below) ( the super nova is the rarest one(0.1 chance))
:) Tip, go to like -100 fast so it is supper fast and you will probably get the best one. Types of guys: Common Uncommon Orange Super Cool Epic Ninja Bug Silver Legend Pirate Flames Rainbow Supernova
