The Re-Spin feature is activated when one or more Firecracker Orbs land on the reels, awarding 8 Re-Spins. The feature continues until all boxes are filled or the 8 Re-Spins are used up. Any prizes collected during the Re-Spins are only awarded once the feature ends.
Triggering a respin is very random, as the appearance of one or more Firecracker Orbs might or might not trigger due to randomness.
