How to win in the Super Bonus Game?
During the Super Bonus Game, the grid expands to 5×5 in size, and players are presented with 25 symbols to pick from. Abundant in tasty jam jars, the reel action offers you a chance to collect bet Multipliers of up to 500x your stake. Each jar contains either a random Multiplier value or nothing, and you climb the Multiplier ladder, proceeding to the next stage after you pick and guess the Multiplier from the previous stage.
You start from the bottom line, and each correct pick unlocks the next row, or stage. Meanwhile, revealing an empty jar ends the Super Bonus Game and the total prize, equal to the accumulated Multiplier value multiplied by the total bet value. However, the first two picks are risk-free, so a win of at least 25x your bet is guaranteed.
| Stage | Available Multipliers | Number of winning cells |
|---|---|---|
| 1 | 10x and 15x | 5 |
| 2 | 15x, 20x, 25x, 30x, and 35x | 5 |
| 3 | 40x, 45x, and 50x | 3 |
| 4 | 75x and 100x | 2 |
| 5 | 300x | 1 |
During the first two stages, jars only contain the above-mentioned bet Multiplier values, though, as you proceed further, some jars will contain zero. There are three winning jars on the third stage, while the other two award nothing and end the bonus game. On stages four and five, the number of winning jars is two and one respectively, so pick carefully to reach the top.
