Guides

How the games work, with the real odds and returns from the games themselves.

• Two-Up rules and the five odds bet: How Two-Up works: two coins, heads or tails, what an odds throw means, and the real chance of five odds in a row: 1 in 32.
• Keno Heads, Tails and Evens explained: Heads or Tails in Keno is a bet on which half of the board gets more of the 20 balls. The exact chances and what each call pays.
• How many numbers should you pick in Keno?: Every Keno ticket from 1 to 10 numbers, with its real return, how often it pays something and its top prize.
• Hold & Spin explained: How a Hold & Spin round starts, how the three respins reset, what the coins are worth and how often the grid fills, with real figures.
• What does RTP mean?: RTP is the share of all money staked that a game pays back over the long run. What 96% means, what it does not mean, and the RTP of every OpalRove game.
• Win, place and quinella bets explained: What win, place and quinella bets mean, how decimal odds work, and how prices are set at OpalRove's virtual greyhound races.
• How Mines multipliers are worked out: Every Opal Mines multiplier is 0.97 divided by the chance of the safe tiles you have dug, so any cash-out point returns 97%. Tables for 1 to 24 mines.
