>>35122747This sounds like a good solution in place of the 6 types idea. I love it though. Use the energy symbols as the interior plastic bag a repeating/tiled type symbol with use of metallic color effects for a foil/holographic feel. Make the balls opaque.
Have a once daily claw game a la Badge Arcade where the white bottoms are clear instead so you can gravitate towards a type you are hoping for giving an element of control and being force to make a choice will make it more enjoyable if rewarded, while becoming addictive if resulting in failure because you feel responsible for the wrong choice and playing again comes with a subtle need for redemption
