KDice is not a game of skill: it's a game of chance. A game reinforced by operant conditioning trained through positive reinforcement given on a variable-length schedule. This is the most effective method of training and reinforcement. Addiction phenomenon in KDice is based on the schedule of reinforcement.
The truth of the matter is that this is a game not worth money. Between the inherent feeling of inadequacy that most internet junkies have and the insidious training method of KDice, however, here we all are, many of us actually paying for a point boost that we can lose at the drop of a hat. We're pigeons clicking a button for food.
So, what's the point? There isn't one. Just be aware that you're playing a game that's full of overly-competitive, inadequate assholes, and you're being conditioned to return again and again for the frustration and abuse. Cheating is rife; losing is commonplace; this game will ruin you because it dictates behavior with no real reward.
Oh, and of all the things we waste in our lives, time is the one thing we can never, ever get back.
