Get ready to reap rewards and raid reels in Bone Raiders. If you can gather the skull and cross bones to create matching symbols in this spine-tingling 5X3 slot, you’ll trigger a respin mechanic with an increasing multiplier for even more chances to win. What’s more, there’s also a bonus round if you can land scatter symbols on reels 2,3 and 4. As the slot expands into 7x7, the chance to convert symbols into coins comes alive.
