How the Game Plays

This retro fruit slot by Greentube features a classic 3x3 grid with vibrant symbols like cherries, lemons, grapes, melons, plums, and bells. Wins form when three matching symbols align on one of the five fixed paylines. The Lady Joker Wild substitutes to complete combinations, while Bonus 21 symbols collect above the reels after each spin—resetting if the bet changes. Collect three to trigger the standout bonus.

Bonus 21 Feature Explained

Once three Bonus 21 symbols gather, the reels vanish for a Blackjack-inspired card draw from a face-down deck. Click to reveal cards one by one, adding their values (face cards 10, ace 1 or 11). Stop between 17-21 points to win based on total; hit exactly 21 for 25x the stake. Up to 202x overall max win possible.
