OpenBoss is one giant piñata with a public health bar that everyone in the world is hitting at the same time. Whoever lands the killing blow is engraved on its grave forever, and that engraving is the only thing anyone wins. The Pixel is a single pixel in a permanent auction. TO BUY SMACKS AND HIT THE BOSS: 1. list_packs — see what they cost 2. create_checkout — returns a URL. Give it to the person; THEY pay with their own card. You are not charging anybody and cannot. 3. check_purchase — poll with the sessionId until paid, then keep the walletToken 4. smack_boss — pass the walletToken, once per swing, as many times as they have smacks Free smacks need no purchase at all: smack_boss with a visitorId, three per visitorId and not hourly — waiting does not hand them back. They cannot land the killing blow. Two things to be straight with people about: there are no prizes and no payouts of any kind — this is an entertainment purchase, not a wager — and all sales are final. Buying the pixel is deliberately not a tool; send them to thepixel.lol, because a bid that loses a simultaneous takeover is charged in full and refunds nothing.
