What it costs
There is no price list, because nobody here sets the price. The clock does.
Each round opens at twice whatever the previous round sold for — with a twenty-five dollar minimum — and falls in a straight line to a five dollar floor over six hours. Whatever number is on screen when you press the button is what you pay. That is the entire pricing model.
There are no accounts to buy, no plans, no credits and no subscriptions. One payment buys one round.
