How the base game pays
The base game is a plain line slot: 5 reels, 4 rows and 50 paylines. A win counts when matching symbols run from the leftmost reel to the right, and only the biggest win on each line is paid. The symbols follow an old Shanghai jazz club: saxophone, snare drum, gramophone and microphone, then A, K, Q, J and 10.
The WILD, a lady with a red flower in her hair, is also the top paying symbol. It stands in for every symbol except the red heart.
The red heart respin bonus
Four or more red hearts in the Main Game start the bonus game with 3 respins. In each respin, any red heart that lands is locked in place and the respin count goes back to 3. So the bonus keeps going for as long as new hearts keep arriving, and the count only resets when a heart lands.
Growing the board from 4x5 to 8x5
The bonus starts on a 4x5 layout, but the board can reach 8x5. Hearts collected on the board unlock the bigger sizes in steps:
- 8 hearts on the board: 5x5 layout
- 12 hearts: 6x5 layout
- 16 hearts: 7x5 layout
- 20 hearts: 8x5 layout
- All 40 positions filled with hearts: the bonus game ends in advance
What the help page leaves out
The help page picture shows numbers on the hearts, such as 500, 1K, 30K and 100K, but the text never explains what a heart is worth or how the bonus total is worked out. The help page does not mention free spins, a jackpot or a Buy Bonus, and it prints no maximum win. We do not fill those gaps with guesses.
Playing it sensibly
Because the bonus is the part the help page explains least, judge the game by what is printed: the line pays. Start with a small bet, watch a few spins to see the heart board for yourself, and decide on a session budget before you begin. Stop when the budget is used, whatever the board looks like.
