Carnival symbols and lines
Wins pay left to right from the leftmost reel on 25 paylines; each line pays only its best win, and wins across lines are combined. The top two symbols are costumed carnival dancers, one in a purple feathered headdress, one in a green feather headpiece, then a purple feathered mask and a coconut drink with a flower. A, K, Q and J fill the lower rows.
The Wild, a dancer in a red and gold heart crown, lands on reels 2 to 5 and replaces every symbol except BONUS, MONEY and COLLECT. Its own pay is not printed.
Disco balls meet the hearts
Each disco-ball MONEY symbol takes a random value from a predefined set on every spin. The rules pages do not print that set, nor the values carried by the EXTRA CREDIT and MULTIPLIER hearts. When one or more MONEY symbols land and any COLLECT heart hits reel 5, one feature is awarded:
- COLLECT (gold heart): the heart adds up every MONEY value showing and pays the sum.
- EXTRA CREDIT COLLECT (blue heart): each MONEY symbol first gets this heart's value on top, then the lot is summed and paid.
- MULTIPLIER COLLECT (pink heart): each MONEY value showing is multiplied by the heart's value before the total is paid.
- EXPANDING COLLECT (red heart): any reel holding a MONEY symbol fills top to bottom with MONEY symbols, each added one taking a new random value, and everything is paid.
- RESPIN COLLECT (green heart): the MONEY symbols lock in place while every other cell spins once more; the MONEY values on the screen afterwards are summed and paid.
Free spins and the bonus pot
The BONUS symbol is a pair of bongo drums that lands on reels 2, 3 and 4; landing three pays 1x total bet and opens 8 free spins. MONEY symbols and all COLLECT features stay active, and every MONEY value that lands is also added to a bonus pot. When the spins end, the pot returns as a giant MONEY symbol on reels 1 to 4 for one final respin; if COLLECT hits reel 5, the pot is paid. The no-COLLECT case is not described. Three more BONUS symbols add 8 spins, and the page says there is no limit to this.
A steady way to play
The paytable amounts were read at a total bet of RM2.00 and change with your bet; bets run from RM0.25 to RM500.00. The MONEY values are not printed, so fix a budget and a stop time first and keep the bet small while the hearts become familiar. The rules pages print no max win and do not mention a Buy Feature.
