What Is the Main Gameplay of 9 Balls?

9 Balls is a slot game from Wazdan featuring a 3×3 grid, giving you 9 separate reels. The main goal is to trigger the Bonus Game by landing three game symbols of any type on the centre row. In standard play, symbol payouts occur only during the Bonus Game or when a symbol appears on a reel marked with the Penalty Kick label and the corresponding countdown reaches zero. Sticky symbols may affect your results, and the top possible payout is 2500 times your stake.

How Does the Betting Work?

Bets in 9 Balls start at a minimum of £0.10 and can go up to a maximum of £5.00 per spin. Players may also choose to increase their chances of entering the Bonus Game by using the xG Chance Level™ feature, increasing their stakes accordingly. The precise return to player value (RTP) is displayed within the game itself.

What Are the Unique Game Features?

Cash Infinityâ„¢

  • During the base game, Cash Infinityâ„¢ symbols may randomly land and stay locked on the reels until the end of the Bonus Game.
  • While these symbols are sticky, other symbols on the reels continue to spin as usual.
  • Each Cash Infinityâ„¢ symbol awards a prize worth between 5x and 15x your bet, paid at the conclusion of the Bonus Game.
  • Landing a Cash Infinityâ„¢ symbol on the centre row increases your likelihood of activating the Bonus Game.

Penalty Kick

  • The base game features no regular symbols.
  • A Penalty Kick label may appear on a random reel and stay there for up to 15 spins.
  • If a game symbol is drawn on a reel carrying the Penalty Kick label when its countdown reaches zero, the payout for that symbol is awarded.

Bonus Game

  • The Bonus Game is played on all nine reels, where all game symbols become fixed in position.
  • Players start with 3 respins (shots). Every new symbol that appears resets the number of respins to 3.
  • The Bonus Game ends when you run out of respins or every reel is occupied by a symbol.
  • Cash symbols offer prizes ranging between 1x and 10x your current bet.
  • Special jackpot symbols, including Quarter Final, Semi Final, and Final Jackpot, may land and offer their respective jackpots.
  • It is possible to win several jackpots of the same type within a single Bonus Game.
  • Collector symbols can randomly accumulate and multiply all values from Cash and Cash Infinityâ„¢ symbols by a factor between 1x and 20x.
  • Mystery symbols are able to transform into any game symbol except for Cash Infinityâ„¢.
  • Jackpot Mystery symbols transform only into one of the Quarter Final, Semi Final, or Final Jackpot symbols.
  • Payouts are made at the end of the Bonus Game, except if the Champion Jackpot is won.
  • If you collect nine symbols of any kind during the Bonus Game, the Champion Jackpot is awarded, providing a payout of 2500 times the bet.
  • Game symbols only award prizes at the conclusion of the Bonus Game.
  • The Champion Jackpot represents the highest possible win in 9 Balls.

xG Chance Levelâ„¢

  • By default, play is at base bet. The xG Chance Levelâ„¢ allows players to choose between three higher levels:
  • x2: Stake doubles, with at least double the chance to activate the Bonus Game.
  • x4: Stake quadruples, with at least four times the chance to enter the Bonus Game.
  • x6: Stake increases sixfold, with at least six times the opportunity to reach the Bonus Game.
  • The values of all symbols remain unchanged regardless of xG Chance Levelâ„¢ selection.
  • Sticky symbols are reset when changing the xG Chance Levelâ„¢, and only reappear if the same level is selected again.

Which Volatility Options Are Available?

Players have the ability to select from three volatility modes to suit their playing style:

  • Low Volatility (Defensive): Generally results in more frequent but typically smaller payouts.
  • Standard Volatility (Balanced): Offers a moderate mix of both payout frequency and size.
  • High Volatility (Offensive): Less frequent wins but with the potential for higher prizes.

How Does the Gamble Feature Operate?

  • The Gamble feature offers the chance to attempt to double your winnings after a successful spin.
  • You may only gamble the value of the current win in your ongoing session.
  • Choose to take your win or select one of two symbols to try to double your prize.
  • The outcome is decided by a draw between the two symbols.
  • You may continue to gamble after each round or choose to collect your winnings at any time.
  • If you lose a round, your winnings up to that point are forfeited and you return to the main game.
  • The gamble feature can be played for up to 7 rounds per win.
  • The maximum amount that can be doubled in a single round is £12,500.
  • For example: If your win is £1,500.00, you can gamble to double it to £3,000.00 in the next round.

Are There Any Additional or Important Details?

  • Game terms and conditions apply to all gameplay.
  • Site procedures manage incomplete or unfinished game rounds, including limits on session inactivity.
  • If a malfunction occurs, all affected wagers and winnings are voided, and all bets are refunded.
  • Unresolved or interrupted games are settled by either a refund or a payout, and incomplete rounds are stored for up to 90 days.
  • Details on return to player can be found in the game interface.
