No room has been drawn yet. Room 1 opens the minute $CHIPROOM is live. Ten chips at 0.01 ETH each fill a room; when the tenth chip lands, a block three ahead is fixed, its hash draws one chip, and that chip takes the room: 0.1 ETH. Place 1 is the first move.
Room 1 is empty. Place 1 is lit: the first chip opens the room.
Holders of 2,000 $CHIPROOM place chips, up to three a room. One chip is a 1-in-10 shot at 0.1 ETH.
