Battle Night is your first chance to play 99 Royale with us. On 30th July, from 7pm to 10pm, Ragnarok and Ra The King go live across our sites for the first time.

For those three hours you can jump in and play both games however you like, on your own or in a live Battle against other players.

99 Royale is a series of slot games with a twist. As well as playing on your own, you can join a live Battle and go head-to-head with other players for a share of a prize.

Each game plays two ways: Solo mode is a standard slot you can play any time, and Battle mode is the multiplayer game. Every spin, in both modes, is a real money wager at your chosen stake.

Head to the Slots section, where you'll find a sub-tab called 99 Royale with both game titles.

Each game has full game rules in the game lobby, found by tapping the "i" icon at the bottom left.

When you pick Battle mode you'll join a queue with other players. While you wait you can spin the solo slot, and anything you win there is yours to keep, it doesn't affect the Battle.

Once enough players have joined, the Battle begins and everyone starts on full Health. Winning spins pay out as normal, and they also build up Power. You spend that Power to "attack" other players, taking their Health while topping up your own.

Get a player's Health to zero and they're "knocked out" from the Battle. The last player standing finishes first, and the top finishers share the Battle Prize.

Winning spins build up Power, and bigger wins and levelling up earn you more of it. When you've got Power to spend, pick a targeting mode and press the Power button to "attack." You choose the type of opponent, not the exact person:

• Random: anyone still in the Battle
• Weakest: players on low Health
• Strongest: players on a high level
• "Attackers": whoever's currently coming after you

It's a cash prize shared between the top finishers. The bigger the Battle, the more players get paid. You'll see the number of paying positions before the Battle starts.

To be in with a chance you just need to place at least one paid spin during the Battle. The figure shown during play is a live estimate and moves around until the Battle ends, when your prize is settled and paid into your account automatically.

The Battle keeps going. If you get back before you're "knocked out" you'll rejoin the same Battle, though you might find you've been "knocked out" while you were away.

Either way, anything you've won is paid into your account.

Yes! Any slot wins are credited to your account as you go, whatever happens in the Battle.

There's no confirmed date for the games coming back yet, but we're working on it and will let you know.
