LastBubble is a live auction shaped like a bubble. A neon bubble bounces across the screen like a classic screensaver while players fight for the lead in real time. Place the last bid before it bursts and take the pot.

How it works:

Every bubble starts with a 24-hour timer.
Each bid must be at least 1 Bubble higher than the last one, goes into the pot and cuts 1% off the time left.
If the time would drop below 5 minutes, the bid resets the timer to 5 minutes.
In the final 5 minutes the bubble swells until it bursts. A bid during that phase shrinks it back and resets the timer to 5 minutes.
When it bursts, the leader takes 91% of the pot.
The other 9% goes to a raffle: up to 3 different players who bid in that bubble win 3% each. Every bid is one ticket, so the more you play, the better your chances, and the leader takes part too.
If only one player bids, their bid is refunded. A new bubble appears 15 seconds later.
