"Dr. Bone Jangles" is a 5-reel, fixed 25-line video reel game with two bonus features. The game pays left to right only. Winning combinations must be on consecutive reels and begin on the first reel. Only the single highest win is paid per wagered payline. The maximum prize per play is $500.00. The "Idol" symbol appears on reels 2, 3 and 4 only and substitutes for all other symbols to help form line wins. When the "Idol" symbol appears on a reel and it can help form line wins by expanding, it will expand to fill the entire reel with wilds. The "Idol" symbol does not help trigger the bonus. When the player increases their bet per line, different reel strips are used at bets of 2, 4, 6, and 8 that will increase the player's payout percentage.
The "Doll" symbol appears on reels 2, 3 and 4 only and will trigger the 'Pick-a-Prize' bonus when 3 appear scattered on screen. In the 'Pick-a-Prize' game, the player is asked to select 5 of the 10 items presented. Selecting an item reveals a prize worth a multiple of the total bet. Two of the ten items also award 5 fever games. The prizes offered during the 'Pick-a-Prize' are 2, 3, 5 and 10 times the total bet that was present when the bonus feature was triggered. At the end of the 'Picka-Prize' bonus, credits found will be awarded to the player.
If the player finds a fever games prize, the 'Fever Games' Feature will play out immediately following the 'Pick-a-Prize' bonus. Main game and bonus game reels do not have the same symbol composition. The maximum allowable bet during the fever games is the same bet that was present when the bonus was triggered. If 3 "Doll" symbols appear on any fever game, the player will receive 10 additional fever games. The maximum number of fever games that can be awarded is 90. The 'Pick-a-Prize' feature will not be awarded during the fever games. During the 'Fever Games' Feature, the "Idol" symbols continue to become full reel wilds. Should 1 or 2 appear on a fever game, the full reel wild(s) will lock in place as well as reels 1 and 5 and any center reel that doesn't have a wild on it will respin to help form new wins. Any prizes formed by an expanding wild will be awarded before the respin feature and then after the respin feature. Respins are free and will not subtract from the fever games counter.
