During Free Spins, colourful Candy Bomb multiplier symbols land randomly and stay in place until all cascades for that individual spin complete. Their values are 2x, 3x, 4x, 5x, 6x, 8x, 10x, 12x, 15x, 20x, 25x, 50x, 100x, 250x, 500x or 1,000x.
When a tumbling sequence ends, the values of all visible bombs are summed. The combined multiplier is then applied to the accumulated win from that spin's cascades. For example: a spin generating $50 in base cascade payouts, with a 15x bomb and a 100x bomb on screen, ends at $50 × (15 + 100) = $5,750 CAD.
Because the values are added, not multiplied, the mathematically decisive scenario is a long cascade chain that happens to coincide with several mid-to-high bombs. Not a single lucky 1,000x bomb landing on a $0.40 tumble. Sorry, that needs restating more plainly: a 1,000x bomb on a tiny cascade is worth far less than three mid bombs on a fat one. That is precisely why the Super Free Spins variant, with a 20x minimum per bomb, shifts the distribution so aggressively.
