Nothing here predicts anything
The Omenator borrows the costume of a Victorian fortune-teller: crystal balls, tea leaves, star charts, cards with grand names. It is costume and nothing else. No symbol, card, cup or constellation says anything about you, your luck, your week or your future, and no result is a hint about the next one. If a crow turns up three times in a row, that is a coincidence with feathers.
Please don’t make real decisions because of something you saw here. We would be genuinely alarmed.
Where the randomness comes from
Every outcome is drawn in your own browser with its built-in cryptographic random number generator, the same source browsers use for security work. Numbers are taken without bias (draws that would tilt the odds towards low numbers are discarded and redrawn), so each drum stop, card, shuffle and wheel segment is exactly as likely as the rules say.
- There is no server deciding results. We could not see your rounds or nudge them even if we wanted to.
- Nothing adjusts to your balance, your streak or how long you have been playing. A round has no memory of the one before.
- Animations are only theatre. The result is settled the moment you press the button; the spinning just shows it to you slowly.
What “average return” means
The average return of a game is the share of the stake it pays back over a very long run. A game with a 93% return pays back 93 coins for every 100 staked, on average, and keeps 7. Individual rounds swing widely either side of that figure; the average only shows itself over thousands of rounds.
Two things worth keeping in mind:
- A returned stake is not a win. If you stake 30 coins and get 30 back, you have broken even. If you get 16 back, you have lost 14, even though coins arrived. The games say which is which.
- Every game here returns less than it takes. Over time your balance will drift downwards. With pretend coins that costs nothing, which is the point: the shape of a casino, without the bill.
Game by game
| Game | Stake | Average return | How we worked it out |
|---|---|---|---|
| Fortune Machine | 10–50 coins | 92.7375% | All 8,000 drum positions on all five lines counted one by one |
| Tarot High Card | 20, 50 or 100 coins | 94.32% to 97.27% | Exact chance of each guess for each of the 22 face-up cards, with ties and whole-coin rounding included |
| Tea Leaves | 15 coins | 93.33% | All 84 ways of choosing three cups from nine |
| Celestial Wheel | 30 coins | 93.75% | The sixteen segment values added up and divided by sixteen |
The figures above are calculated by the site itself from the same rule tables the games load, so if a rule ever changed, the number on this page would change with it.
About the coins themselves
Coins exist only as a number saved in your browser. They are not money, not cryptocurrency and not a voucher for anything. You cannot buy more, sell them, swap them, send them to someone else or turn them into a prize. When they run low the house simply hands you more: 1,000 when you sign up, 500 as tea money once a day, and a refill to 250 whenever you are too short to play.
