32 jellyfish sleep in a honeycomb reef. You spark one. When a jelly lights up it flashes a ring of light, and every jelly inside that ring lights next. The chain runs until no new jelly is reached. Your prize depends on how many jellies light up.
The jelly you tap always flashes at least BRIGHT, so your spark always reaches its neighbours. Jellies near the middle have the most neighbours.
Some reefs hold a gold jelly marked ×2, ×3, ×5 or ×10, and now and then a second one. You can't spark gold directly. When the chain lights a gold jelly, your whole prize is multiplied. Two golds multiply together. Top prize ×200.
Each reef, including every secret flash size and gold jelly, is built from a server seed that is locked before you bet. You see its fingerprint first. After the round the seed is revealed, and your browser rebuilds the reef and checks it matches.
