Gameplay and Stake Selection
You choose one colour from Turquoise, Coral, or Gold and select a stake of 5, 10, 25, 50, or 100 coins. Clicking the button lights three lanterns that independently pick a colour. The default setting is Turquoise with a 10-coin stake. You can only start one round at a time, and all controls lock while the round is active.
Probabilities and Payout Structure
Matching zero colours pays nothing. One match returns 90% of your stake, two matches return 180%, and three matches return 432%. The probability of at least one match is 19/27. The expected gross return is exactly 96%, though this is not guaranteed for any single session. Fractional carry is preserved in the background.
Wallet Rules and Settlement
Your stake is deducted immediately upon starting. The round settles automatically after 650 milliseconds. If you reload during this time, you lose the deducted stake with no refund. You can manually restore your balance to 1000 coins only when idle and below 5 coins. Carried fractional cents are saved for the next round.
