The dog's sonar is another distraction; this is the same as the child's expenditure, but it also triggers a free spin. The amount of rotation is as follows: 5 dogs = 20 rotations, 5 multipliers, 4 dogs = 15 rotations, 4 multipliers and 3 dogs = 10 rotations, 3 multipliers.
During the free spin, the game is no different, I think the Blaster captain can benefit from more features. You will get new information above the reels, count down your rotation and total your victory. You can also re-trigger the reward by hitting more than 3 dogs anywhere on the reels. Before your free spin multiple is awarded, the victory including the captain doubles - making it possible for you to get some great wins from this feature. Once completed, you only need to see the total prize and go straight back to the regular game.
