Your play level sits at the bottom of the screen, right next to the Base Play and Coin Type settings. Use the arrows on either side of the Play Level display to move it up or down until you land on the amount you want.

Coin
the Bonus symbol here, appearing in both the main game and the Bonus Game. Each one shows the prize it awards on the spot: a Max Jackpot (100x total play), Mid Jackpot (50x), Min Jackpot (20x), or a Regular Prize equal to total play multiplied by a value between x1 and x5 in the main game, or up to x10 during the Bonus Game.

Special
3 Chests above the reels:

• Red (Boost)
• Green (Mystery)
• Purple (Collect). 

Landing 4 regular symbols in the center row triggers the Hold & Win Bonus Game and any Chests that activate along the way decide which special symbols show up once the feature starts. More than one Chest can activate at the same time, stacking their symbols together.

Activated Chests add their matching special symbol to the grid before the feature begins and any Sticky symbols already on the board turn into Bonus symbols that carry their prize straight into the round. 

The Bonus Game opens with 3 attempts and every new symbol that lands resets that counter back to 3. It keeps going until you're out of attempts or the whole grid fills with Bonus and special symbols, at which point every value on the board is added up for the total. 

Collecting 12 Bonus and/or special symbols (Boost aside) along the way adds an extra Ultra Jackpot worth 1000x your total play.

Collector feature
the Collect symbol pulls in the value of every Bonus symbol currently on the grid and adds it to its own total. Each Collect symbol only activates once per round.

Chance game
after a win, choose one of four face-down cards to go up against the dealer's card. Beat it and your prize doubles, with up to 10 attempts to keep the streak going. Lose to the dealer and the round ends there, though a tie simply gives you another go. The Joker always wins and you can walk away with your current prize at any point.
